# Requirements Document
## Introduction
Ce document spécifie les exigences pour le système de visualisation interactive des échanges TR-069/CWMP. L'objectif est de remplacer le viewer de log brut actuel par une interface de type diagramme de séquence CPE ↔ ACS, permettant d'inspecter individuellement chaque message SOAP échangé lors d'une session de trace. Le stockage passe d'un format texte brut (fichiers `.log`) à un stockage structuré en MongoDB. L'UI utilise le framework Boosted (Orange CSS basé sur Bootstrap) et s'intègre à la page DeviceDetail existante.
## Glossary
- **Exchange_Store**: Service backend responsable du stockage et de la récupération des échanges CWMP structurés dans MongoDB
- **Exchange_API**: Endpoints REST exposant les échanges structurés d'un device tracé
- **Sequence_Viewer**: Composant frontend Vue 3 affichant le diagramme de séquence CPE ↔ ACS avec les messages cliquables
- **Inspector_Panel**: Panneau latéral affichant le contenu XML SOAP formaté du message sélectionné
- **CWMP_Message**: Un échange SOAP individuel capturé (requête ou réponse) avec ses métadonnées (direction, timestamp, type CWMP, XML brut)
- **Trace_Session**: Période pendant laquelle un device est en mode trace, regroupant tous les échanges capturés
- **CPE**: Customer Premises Equipment — l'équipement réseau du client qui communique avec l'ACS via TR-069
- **ACS**: Auto-Configuration Server — le serveur adam-acs qui gère les CPE via le protocole CWMP
- **Boosted**: Framework CSS Orange basé sur Bootstrap, utilisé pour le design system de l'application
- **SSE**: Server-Sent Events — protocole HTTP unidirectionnel (serveur → client) permettant au backend de pousser des événements en temps réel vers le navigateur via une connexion persistante
## Requirements
### Requirement 1: Stockage structuré des échanges
**User Story:** As a developer, I want CWMP exchanges to be stored in a structured format in MongoDB, so that individual messages can be queried and displayed independently.
#### Acceptance Criteria
1. WHEN CwmpLoggerMiddleware captures a SOAP exchange for a traced device, THE Exchange_Store SHALL persist a CWMP_Message document in MongoDB containing: deviceId, direction (CPE→ACS or ACS→CPE), timestamp (ISO 8601 UTC format), sessionId, cwmpMethod (type de message CWMP extrait du XML), rawXml (limited to 2 MB maximum per message), and a monotonically increasing sequence number per device starting at 1
2. THE Exchange_Store SHALL extract the CWMP method name from the SOAP body element by reading the first child element name under the `cwmp:` namespace prefix (e.g., "Inform", "GetParameterValues", "SetParameterValuesResponse") and store it in the cwmpMethod field
3. IF the SOAP body contains no element with the `cwmp:` namespace prefix (malformed or unrecognized XML), THEN THE Exchange_Store SHALL persist the message with cwmpMethod set to "Unknown" and store the original rawXml unchanged
4. WHILE a device is in trace mode, THE Exchange_Store SHALL persist all exchanges in chronological order, retaining a maximum of 5000 messages per device, and deleting the oldest messages when this limit is exceeded. THE Exchange_Store SHALL NOT persist messages for devices that are not currently in trace mode
5. THE Exchange_Store SHALL create a MongoDB index on (deviceId, timestamp) to support efficient retrieval of exchanges by device
6. IF the XML body is empty (empty POST from CPE), THEN THE Exchange_Store SHALL persist the message with cwmpMethod set to "Empty" and rawXml set to an empty string
7. IF a MongoDB write failure occurs during message persistence, THEN:
- FOR critical messages (RPC Calls, Responses, and Faults such as Inform, GetParameterValues, SetParameterValuesResponse, Fault): THE Exchange_Store SHALL attempt 3 retries with exponential backoff (1s, 2s, 4s) before discarding
- FOR non-critical messages (Empty posts, Unknown method types): THE Exchange_Store SHALL log the error and discard the message immediately
- In both cases, THE Exchange_Store SHALL NOT interrupt the CWMP session processing
### Requirement 2: API de récupération des échanges structurés
**User Story:** As a frontend developer, I want a REST API to retrieve structured CWMP exchanges for a traced device, so that the sequence viewer can display them.
#### Acceptance Criteria
1. WHEN a GET request is made to `/api/v1/tr069-trace/:deviceId/exchanges`, THE Exchange_API SHALL return a JSON array of CWMP_Message objects ordered by timestamp ascending, where each CWMP_Message contains at minimum: timestamp (ISO 8601), direction (CPE→ACS or ACS→CPE), messageType (e.g. Inform, GetParameterValuesResponse), and sessionId
2. WHEN a GET request is made with a `limit` query parameter, THE Exchange_API SHALL cap the number of returned messages to the specified value, defaulting to 200 when omitted, and clamping to a maximum of 1000
3. IF the `limit` query parameter is present but is non-numeric or less than 1, THEN THE Exchange_API SHALL return a 400 status with an error message indicating the valid range (1 to 1000)
4. WHEN a GET request is made with an `after` query parameter containing a valid ISO 8601 timestamp, THE Exchange_API SHALL return only messages with a timestamp strictly greater than the specified value, enabling incremental polling
5. IF the `after` query parameter is present but is not a valid ISO 8601 timestamp, THEN THE Exchange_API SHALL return a 400 status with an error message indicating the expected format
6. IF the device identified by `:deviceId` has never been traced (no historical exchanges exist), THEN THE Exchange_API SHALL return a 404 status with an error message indicating that no trace exists for this device
7. WHEN a GET request is made for a device that is being traced but has no recorded exchanges, THE Exchange_API SHALL return a 200 status with an empty JSON array
8. WHEN a GET request is made for a device that was previously traced but tracing is now stopped, THE Exchange_API SHALL return a 200 status with existing historical exchanges AND include metadata: traceStatus ("ACTIVE" or "STOPPED"), traceStoppedAt (ISO 8601 timestamp if stopped), recordedFrom (timestamp of oldest exchange), and recordedUntil (timestamp of newest exchange)
9. WHEN a DELETE request is made to `/api/v1/tr069-trace/:deviceId/exchanges`, THE Exchange_API SHALL remove all stored exchanges for the device and return a 204 status with no body
### Requirement 3: Intégration dans DeviceDetail
**User Story:** As an operator, I want to access the exchange viewer directly from the device detail page when the device is in trace mode, so that I can inspect protocol exchanges without navigating to a separate page.
#### Acceptance Criteria
1. WHILE a device is in trace mode, THE DeviceDetail page SHALL display a collapsible section containing the Sequence_Viewer, positioned after the Actions section
2. IF the device is not in trace mode, THEN THE DeviceDetail page SHALL display a button allowing the user to enable tracing for the device, within the Actions section. WHILE the device is in trace mode, THE button SHALL remain visible but disabled with a tooltip "Tracing already active. Click 'Disable Tracing' to stop." AND a secondary "Disable Tracing" button SHALL be displayed adjacent to it
3. WHEN the user enables tracing from DeviceDetail, THE DeviceDetail page SHALL display the Sequence_Viewer section showing an empty state message indicating that the system is waiting for the next device connection. The system SHALL allow tracing to be enabled regardless of response time constraints
4. WHILE a device is in trace mode, THE DeviceDetail page SHALL display a session header within the Sequence_Viewer section showing: device identifier, manufacturer, product class, serial number, and trace start time as recorded when tracing was enabled
5. WHEN the Sequence_Viewer section is displayed and no protocol exchanges have been recorded yet, THE DeviceDetail page SHALL display an empty state indicating that no exchanges are available and that data will appear on the next device connection
### Requirement 4: Diagramme de séquence interactif
**User Story:** As an operator, I want to see CWMP exchanges displayed as a sequence diagram with CPE and ACS lifelines, so that I can visually understand the protocol flow.
#### Acceptance Criteria
1. THE Sequence_Viewer SHALL display two vertical lifelines labeled "CPE" and "ACS"
2. THE Sequence_Viewer SHALL render each CWMP_Message as a horizontal arrow between the two lifelines, pointing in the direction of the message (CPE→ACS: left to right, ACS→CPE: right to left), ordered by timestamp ascending
3. THE Sequence_Viewer SHALL display the cwmpMethod name as a label on each arrow, truncated to 40 characters with a tooltip showing the full name if the label exceeds this length
4. THE Sequence_Viewer SHALL display the timestamp of each message in "HH:mm:ss.SSS" format below the method label
5. WHEN the user clicks on a message arrow, THE Sequence_Viewer SHALL apply a visually distinct background color to the selected message row, deselect any previously selected message, and display the selected message's content in the Inspector_Panel
6. THE Sequence_Viewer SHALL use distinct visual styling (color or line style) to differentiate CPE→ACS messages from ACS→CPE messages
7. THE Sequence_Viewer SHALL use Boosted CSS framework classes and Orange design tokens for all styling
8. WHEN no CWMP_Message exists for the current device, THE Sequence_Viewer SHALL display ONLY a placeholder message without rendering the lifelines, to avoid rendering empty UI elements
### Requirement 5: Panneau d'inspection XML
**User Story:** As an operator, I want to see the full formatted XML SOAP content of a selected message, so that I can debug protocol issues.
#### Acceptance Criteria
1. WHEN a message is selected in the Sequence_Viewer, THE Inspector_Panel SHALL display the rawXml content formatted with 2-space indentation and syntax highlighting that visually distinguishes XML elements, attributes, and values using distinct colors
2. WHEN a message is selected in the Sequence_Viewer, THE Inspector_Panel SHALL display a header showing the cwmpMethod name and the message direction expressed as "CPE→ACS" or "ACS→CPE"
3. WHEN the operator activates the "Copy" button, THE Inspector_Panel SHALL copy the raw unformatted XML content to the system clipboard and display a transient confirmation indicator visible for at least 2 seconds
4. THE Inspector_Panel SHALL be displayed as a resizable side panel on the right side of the Sequence_Viewer with a minimum width of 300px and a maximum width of 70% of the viewport width
5. WHEN no message is selected, THE Inspector_Panel SHALL display a placeholder text indicating the user should select a message to inspect
6. IF the rawXml content of the selected message is empty or cannot be parsed, THEN THE Inspector_Panel SHALL display a message indicating that no XML content is available for the selected message
### Requirement 6: Mise à jour en temps réel via SSE
**User Story:** As an operator, I want to see new exchanges appearing in the sequence diagram in real-time as they happen, so that I can monitor live protocol activity without delay.
#### Acceptance Criteria
1. THE Exchange_API SHALL expose a SSE endpoint at `GET /api/v1/tr069-trace/:deviceId/exchanges/stream` that opens a persistent HTTP connection with `Content-Type: text/event-stream` and pushes each new CWMP_Message as a JSON-encoded SSE `data` event as soon as it is persisted by the Exchange_Store
2. WHEN the Sequence_Viewer is opened for a traced device, THE Sequence_Viewer SHALL establish an EventSource connection to the SSE endpoint and listen for incoming messages
3. WHEN a new SSE event is received, THE Sequence_Viewer SHALL append the CWMP_Message to the bottom of the diagram while preserving the current scroll position and the currently selected message (if any)
4. THE Sequence_Viewer SHALL display a visual indicator distinguishing between three connection states: "connected" (SSE stream open and receiving), "paused" (auto-scroll paused but still connected), and "disconnected" (connection lost)
5. WHEN the user's scroll position is not at the bottom of the diagram AND the SSE connection is active, THE Sequence_Viewer SHALL pause auto-scroll but continue receiving SSE events in the background
6. WHILE auto-scroll is paused, THE Sequence_Viewer SHALL display a visible button allowing the user to resume auto-scroll, which scrolls the diagram to the latest message and re-enables auto-scroll
7. IF the SSE connection is lost (network error, server restart, or timeout), THEN THE Sequence_Viewer SHALL update the visual indicator to "disconnected" state, preserve all previously displayed messages, and attempt automatic reconnection using the EventSource built-in reconnection mechanism with a retry interval of 3 seconds
8. WHEN the SSE connection is re-established after a disconnection, THE Sequence_Viewer SHALL send the `Last-Event-ID` header (set to the sequence number of the last received message) so that the server resumes from where the client left off without duplicating messages
9. THE SSE endpoint SHALL assign a unique `id` field to each event (using the CWMP_Message sequence number) to support the `Last-Event-ID` reconnection mechanism
10. WHEN the Sequence_Viewer is closed or the user navigates away from the DeviceDetail page, THE Sequence_Viewer SHALL close the EventSource connection to free server resources. THE SSE endpoint SHALL also implement server-side connection timeouts: inactivity timeout of 5 minutes (no new exchanges pushed) and absolute timeout of 2 hours, to free resources for abandoned connections. WHEN a server-side timeout occurs, THE server SHALL close the connection gracefully, triggering client-side reconnection
11. IF the device is not currently being traced, THEN THE SSE endpoint SHALL return a 404 status and close the connection immediately
### Requirement 7: Performance et pagination
**User Story:** As an operator working with devices that generate hundreds of exchanges, I want the viewer to remain responsive, so that I can navigate through large sessions without lag.
#### Acceptance Criteria
1. THE Sequence_Viewer SHALL implement virtual scrolling or pagination to handle sessions with more than 200 messages while maintaining a frame render time of 100 milliseconds or less
2. IF the session contains more than 200 messages, THEN THE Sequence_Viewer SHALL load messages in batches of 50, display the most recent batch first, and provide scroll-based or button-based navigation to access older messages
3. THE Exchange_Store SHALL support a TTL (time-to-live) mechanism that automatically removes exchanges older than 24 hours to prevent unbounded storage growth
4. IF an exchange retrieval request elapsed time exceeds 5 seconds, THEN THE Exchange_API SHALL return a partial result containing the most recent messages in reverse-chronological order, along with an `isTruncated: true` flag and the total number of available messages
### Requirement 8: Purge et gestion des échanges
**User Story:** As an operator, I want to clear the exchange history for a device, so that I can start a fresh observation session.
#### Acceptance Criteria
1. WHILE a traced device is selected in the log viewer, THE Sequence_Viewer SHALL display a "Clear exchanges" button that deletes all stored server-side exchange logs for that device
2. WHEN the user clicks the "Clear exchanges" button, THE Sequence_Viewer SHALL display a confirmation dialog requesting explicit acceptance before proceeding with deletion
3. IF the user cancels the confirmation dialog, THEN THE Sequence_Viewer SHALL close the dialog and leave the existing exchange log unchanged
4. WHEN the user confirms the deletion AND the server returns a successful response (204), THE Sequence_Viewer SHALL:
- Verify the SSE connection remains active
- Reset the log panel to an empty state displaying a "No log entries yet" message
- Continue receiving new messages via the active SSE connection
- IF SSE becomes inactive during or after the clear operation, attempt automatic reconnection before resuming
5. IF the server fails to clear the exchanges, THEN THE Sequence_Viewer SHALL display an error message indicating the failure and preserve the current exchange log content

## Notes
- Tasks marked with `*` are optional and can be skipped for faster MVP
- Each task references specific requirements for traceability
- Checkpoints ensure incremental validation
- Property tests validate universal correctness properties from the design document
- Unit tests validate specific examples and edge cases
- Phase 1 (tasks 0-10) delivers a working MVP with dual-write safety
- Phase 2 (tasks 11-12) adds robustness for production load
- Phase 3 (tasks 13-14) adds documentation and observability
- The dual-write approach in task 5.1 ensures rollback safety: old file-based system continues until new system is validated
- All frontend components use Boosted (Orange CSS) framework — no additional CSS framework needed
## Testing Strategy
### Test Pyramid
| Level | Count | Description |
|-------|-------|-------------|
| Property Tests | 14 | Universal correctness properties (fast-check, 100+ iterations) |
| Unit Tests | 40+ | Example-based tests for specific behaviors and edge cases |
| Integration Tests | 6 | End-to-end flow validation (lifecycle, SSE, cap, TTL, clear, reconnection) |
### Test Coverage Goals
| Type | Target | Rationale |
|------|--------|-----------|
| Unit Tests | 85%+ | Core services and controllers must be well-covered |
| Integration Tests | 80%+ | Critical flows must be validated end-to-end |
| E2E Tests | 60%+ (future) | UI flows with real browser — deferred to post-MVP |
### Running Tests
```bash
# Run all tests
npm run test
# Run unit tests only
npm run test:unit
# Run integration tests only
npm run test:integration
# Run tests in watch mode (development)
npm run test:watch
# Run with coverage report
npm run test:coverage
```
## Rollback & Contingency Plan
### Phase 1 Rollback (Persistence & SSE)
| Feature Flag | Effect |
|--------------|--------|
| `FEATURE_EXCHANGE_PERSISTENCE=false` | Disables MongoDB writes; CWMP sessions continue unaffected |
| `FEATURE_SSE_ENABLED=false` | Disables SSE streaming; frontend falls back to REST polling (5s) |
### Phase 2 Rollback (API Source)
| Feature Flag | Effect |
|--------------|--------|
| `FEATURE_EXCHANGE_API_SOURCE=file` | Frontend reads from old file-based system instead of MongoDB |
Fallback logic in `DeviceDetail.vue`:
```typescript
const exchanges = await api.getExchanges(deviceId)
.catch(() => legacyService.readExchanges(deviceId))
```
### Data Consistency Checks
- Compare file-based exchange count vs MongoDB count for same device
- Alert if discrepancy > 5% over a 1-hour window
- During dual-write phase, periodically verify both systems agree on latest messages
## Known Risks & Mitigations
| # | Risk | Impact | Mitigation | Related Tasks |
|---|------|--------|------------|---------------|
| 1 | MongoDB write latency > 100ms | Messages queued, potential lag | Write batching, monitor p95, alert at threshold | 14.3, 14.4 |
| 2 | SSE connection limit (100+ concurrent) | Server resource exhaustion | Connection pooling, rate limiting per device (max 5) | 4.5, 14.4 |
| 3 | Message loss during MongoDB failure | Gaps in exchange history | Retry logic (3x for critical), dual-write phase | 2.6, 5.1 |
| 4 | Memory leak in EventEmitter | Gradual server degradation | Listener cleanup on disconnect, connection timeouts (5min/2h) | 4.5, 8.1 |
| 5 | Large XML payloads (>2MB) | Storage bloat, slow queries | Truncation at 2MB, monitoring, alert on frequent truncation | 2.1, 14.2 |
| 6 | Browser memory with 1000+ messages | UI freeze, tab crash | Virtual scrolling, client-side cap at 1000 messages | 11.1, 11.3 |
| 7 | SSE reconnection storm (many clients) | Server overload | Exponential backoff (3s base), max retry limit | 8.1, 7.2 |
| 8 | Concurrent clear operations | Race condition, data corruption | Optimistic locking or queue-based deletion | 7.5, 4.1 |
### Mitigation Checklist
- [ ] Write batching implemented (Risk 1) → Task 2.1
- [ ] SSE connection limit enforced (Risk 2) → Task 4.5
- [ ] Retry logic tested (Risk 3) → Task 2.6, 2.7
- [ ] Listener cleanup verified (Risk 4) → Task 4.5
- [ ] 2MB truncation with logging (Risk 5) → Task 2.1
- [ ] Virtual scrolling + memory cap (Risk 6) → Tasks 11.1, 11.3
- [ ] Reconnection backoff configured (Risk 7) → Task 8.1
- [ ] Concurrent deletion handled (Risk 8) → Task 4.1

API REST pour la récupération, la suppression et le streaming en temps réel
des échanges CWMP/TR-069 capturés lors d'une session de trace sur un device.
## Architecture
Les échanges SOAP sont capturés par le `CwmpLoggerMiddleware`, persistés dans
MongoDB via `ExchangeStoreService`, et diffusés en temps réel via Server-Sent Events (SSE).
## Authentification
Tous les endpoints nécessitent une session authentifiée (cookie-based via AdonisJS).
## Feature Flags

summary: Flux SSE temps réel des échanges CWMP
description: |
Ouvre une connexion HTTP persistante avec `Content-Type: text/event-stream`
qui pousse chaque nouvel échange CWMP dès qu'il est persisté.
## Protocole SSE
La connexion utilise le protocole Server-Sent Events (SSE) standard :
- **Content-Type** : `text/event-stream`
- **Cache-Control** : `no-cache`
- **Connection** : `keep-alive`
- **X-Accel-Buffering** : `no` (pour nginx)
## Format des événements
Chaque événement SSE contient :
```
id: <sequenceNumber>
data: <JSON-encoded CwmpExchange>
```
Exemple d'événement brut :
```
id: 42
data: {"sequenceNumber":42,"timestamp":"2025-01-15T10:30:00.123Z","direction":"CPE→ACS","cwmpMethod":"Inform","sessionId":"10.0.0.1:54321->192.168.1.1:8080","rawXml":"<soap-env:Envelope>...</soap-env:Envelope>"}
```
## Reconnexion (Last-Event-ID)
Lors d'une reconnexion, le client envoie l'en-tête `Last-Event-ID` avec le
`sequenceNumber` du dernier événement reçu. Le serveur reprend alors à partir
du message suivant (sequenceNumber > Last-Event-ID), sans duplication.
Le serveur envoie un champ `retry` au début de la connexion (défaut: 3000ms)
pour configurer l'intervalle de reconnexion automatique du client.
## Timeouts serveur
Le serveur ferme la connexion dans les cas suivants :
- **Inactivité** : aucun nouvel échange poussé pendant 5 minutes
- **Durée absolue** : connexion ouverte depuis plus de 2 heures
Dans les deux cas, le client devrait se reconnecter automatiquement
(mécanisme natif EventSource avec Last-Event-ID).
## Feature Flag
Si `FEATURE_SSE_ENABLED=false`, cet endpoint retourne HTTP 503.

# Deployment Guide: TR-069 Exchange Viewer
## Overview
The TR-069 Exchange Viewer stores CWMP protocol exchanges in MongoDB and streams them in real-time via SSE (Server-Sent Events) to a frontend sequence diagram. This guide covers the infrastructure requirements, configuration, feature flags, and monitoring needed for deployment.
## MongoDB Setup
### Requirements
- **MongoDB version**: 4.4+ (tested with 5.0 and 6.0)
- **Replica set**: Not required. The system uses an in-process EventEmitter for real-time notifications instead of MongoDB Change Streams.
- **Authentication**: Standard MongoDB credentials (same as the existing adam-acs database)
### Collections
The feature creates two MongoDB collections:
| Collection | Purpose |
|-----------|---------|
| `cwmp_exchanges` | Stores structured CWMP exchange documents |
| `cwmp_exchange_counters` | Atomic counters for per-device sequence number generation |
### Indexes
Three indexes are created on `cwmp_exchanges`:
| Name | Fields | Options | Purpose |
|------|--------|---------|---------|
| `idx_deviceId_timestamp` | `{ deviceId: 1, timestamp: 1 }` | — | Efficient retrieval by device, ordered by time |
| `idx_deviceId_sequenceNumber` | `{ deviceId: 1, sequenceNumber: 1 }` | `unique: true` | Atomic sequence numbering, Last-Event-ID queries |
| `idx_createdAt_ttl` | `{ createdAt: 1 }` | `expireAfterSeconds: 86400` | Auto-remove exchanges older than 24 hours |
### Running the Migration
Indexes and collections are created via migration `011_create_cwmp_exchanges_collection.ts`:
```bash
# Run all pending migrations
node ace migration:run
# Verify migration applied
node ace migration:status
```
### Index Verification
On startup, the application checks that all expected indexes exist and logs warnings if any are missing. The health check endpoint also reports index status (see [Health Check](#health-check-endpoint) below).
To manually verify indexes in the MongoDB shell:
```javascript
db.cwmp_exchanges.getIndexes()
// Expected: _id, idx_deviceId_timestamp, idx_deviceId_sequenceNumber, idx_createdAt_ttl
```
### Storage Considerations
- **TTL**: Documents are automatically removed after 24 hours (configurable via `EXCHANGE_STORE_TTL_SECONDS`)
- **Message cap**: Maximum 5000 exchanges per device (configurable via `EXCHANGE_STORE_MAX_MESSAGES`)
- **Document size**: Each exchange document stores raw XML (max 2 MB per message)
- **Estimated storage**: For 100 traced devices with 5000 messages averaging 10 KB each → ~5 GB peak

EXCHANGE_STORE_RETRY_MAX_ATTEMPTS=3
EXCHANGE_STORE_RETRY_BASE_DELAY_MS=1000
```

## Feature Flags Usage and Toggle Procedures
The system uses three feature flags for gradual rollout and safe rollback. All flags can be toggled at runtime by changing environment variables and restarting the application.
### FEATURE_EXCHANGE_PERSISTENCE
Controls whether CWMP exchanges are written to MongoDB.
| Value | Behavior |
|-------|----------|
| `true` (default) | Exchanges are persisted to MongoDB for traced devices |
| `false` | No writes to MongoDB; CWMP sessions continue unaffected |
**When to disable:**
- MongoDB is experiencing high latency or unavailability
- Storage exhaustion on the MongoDB server
- You need to temporarily reduce load on the database
**Toggle procedure:**
```bash
# Disable persistence
export FEATURE_EXCHANGE_PERSISTENCE=false
# Restart the application
docker compose restart app
```
> Note: Disabling persistence means no new exchanges are stored. Existing exchanges remain queryable until TTL expires.
### FEATURE_SSE_ENABLED
Controls the real-time streaming endpoint.
| Value | Behavior |
|-------|----------|
| `true` (default) | SSE endpoint is available at `/api/v1/tr069-trace/:deviceId/exchanges/stream` |
| `false` | SSE endpoint returns 503; frontend falls back to REST polling every 5 seconds |
**When to disable:**
- High number of concurrent SSE connections causing resource exhaustion
- Network infrastructure (proxy/load balancer) not supporting long-lived connections
- Debugging connectivity issues
**Toggle procedure:**
```bash
# Disable SSE streaming
export FEATURE_SSE_ENABLED=false
# Restart the application
docker compose restart app
```
> Note: The frontend automatically falls back to REST polling (5-second interval) when SSE is unavailable. No user action required.
### FEATURE_EXCHANGE_API_SOURCE
Controls where the Exchange API reads data from.
| Value | Behavior |
|-------|----------|
| `mongodb` (default) | API reads from the `cwmp_exchanges` MongoDB collection |
| `file` | API reads from the legacy file-based trace system |
**When to switch to `file`:**
- MongoDB data is corrupted or inconsistent
- Rollback to the previous system during migration
- Comparing outputs between old and new systems
**Toggle procedure:**
```bash
# Fallback to file-based system
export FEATURE_EXCHANGE_API_SOURCE=file
# Restart the application
docker compose restart app
```
### Recommended Rollout Sequence
1. **Phase 1 — Dual-write** (default state):
- `FEATURE_EXCHANGE_PERSISTENCE=true`
- `FEATURE_SSE_ENABLED=true`
- `FEATURE_EXCHANGE_API_SOURCE=mongodb`
- Old file-based system continues writing in parallel (dual-write)
2. **Phase 2 — Validate**:
- Compare file-based and MongoDB exchange counts
- Monitor health check for discrepancies
- Verify SSE connections are stable
3. **Phase 3 — Full cutover**:
- Remove file-based writes from `CwmpLoggerMiddleware`
- `FEATURE_EXCHANGE_API_SOURCE=mongodb` (permanently)
### Emergency Rollback
To fully disable the exchange viewer feature without stopping the application:
```bash
export FEATURE_EXCHANGE_PERSISTENCE=false
export FEATURE_SSE_ENABLED=false
export FEATURE_EXCHANGE_API_SOURCE=file
docker compose restart app
```
This restores pre-feature behavior: no MongoDB writes, no SSE connections, and the API reads from the legacy file system.
---
## Health Check Endpoint
### Endpoint
```
GET /api/v1/health
```
The existing health check endpoint (`/api/v1/health`) reports on the overall application status including MongoDB connectivity and `cwmp_exchanges` index status.
### Response Format
```json
{
"status": "OK",
"version": "1.0.0",
"indexes": {
"cwmp_exchanges": {
"allPresent": true,
"indexes": [
{ "name": "idx_deviceId_timestamp", "present": true },
{ "name": "idx_deviceId_sequenceNumber", "present": true },
{ "name": "idx_createdAt_ttl", "present": true }
]
}
}
}
```
### Status Codes
| Status | Code | Meaning |
|--------|------|---------|
| OK | 200 | MongoDB connected, all indexes present |
| KO | 503 | MongoDB unreachable or critical failure |
### Monitoring Recommendations
| Metric | Threshold | Action |
|--------|-----------|--------|
| Health check status `KO` | Any occurrence | Investigate MongoDB connectivity |
| Missing indexes (`allPresent: false`) | Any occurrence | Re-run migration: `node ace migration:run` |
| MongoDB ping latency | > 100ms p95 | Check MongoDB server load |
| Active SSE connections | > 100 total | Consider scaling or limiting connections |
### Integration with Monitoring Tools
The health check endpoint can be used with standard monitoring tools:
```bash
# Simple liveness check (Docker HEALTHCHECK)
curl -f http://localhost:8080/api/v1/health || exit 1
# Kubernetes readiness probe
livenessProbe:
httpGet:
path: /api/v1/health
port: 8080
initialDelaySeconds: 10
periodSeconds: 30
# Nagios/Zabbix check
curl -s http://localhost:8080/api/v1/health | jq -e '.status == "OK"'
```
---
## API Endpoints
The feature exposes three endpoints under the `/api/v1` prefix:
| Method | Path | Description |
|--------|------|-------------|
| GET | `/api/v1/tr069-trace/:deviceId/exchanges` | Retrieve exchanges (paginated) |
| DELETE | `/api/v1/tr069-trace/:deviceId/exchanges` | Purge all exchanges for a device |
| GET | `/api/v1/tr069-trace/:deviceId/exchanges/stream` | SSE endpoint for real-time streaming |
---
## Reverse Proxy Configuration
If running behind a reverse proxy (nginx, Traefik, etc.), configure it to support SSE:
### Nginx
```nginx
location /api/v1/tr069-trace/ {
proxy_pass http://app:8080;
proxy_http_version 1.1;
proxy_set_header Connection '';
proxy_buffering off;
proxy_cache off;
proxy_read_timeout 7200s; # Match absolute timeout (2h)
chunked_transfer_encoding off;
}
```
### Traefik
```yaml
http:
middlewares:
sse-headers:
headers:
customResponseHeaders:
X-Accel-Buffering: "no"
services:
adam-acs:
loadBalancer:
responseForwarding:
flushInterval: "0ms"
```
---
## Docker Deployment
No additional Docker services are needed. The feature uses the existing MongoDB instance.
```yaml
# docker-compose.yml (relevant section)
services:
app:
environment:
- FEATURE_EXCHANGE_PERSISTENCE=true
- FEATURE_SSE_ENABLED=true
- FEATURE_EXCHANGE_API_SOURCE=mongodb
depends_on:
- mongodb
```
Ensure the MongoDB container has sufficient storage for exchange data (see [Storage Considerations](#storage-considerations)).

# Guide de migration : TR-069 Exchange Viewer
## Résumé
Ce guide décrit la migration du système de trace TR-069 depuis le stockage fichier (logs `.log` rotatifs) vers le stockage structuré MongoDB (`cwmp_exchanges`). La migration suit une approche en 3 phases pour garantir zéro perte de données et un rollback possible à chaque étape.
| Phase | Durée | Description | Risque |
|-------|-------|-------------|--------|
| Phase 1 — Dual-Write | Semaines 1-2 | Écriture simultanée fichiers + MongoDB | Faible |
| Phase 2 — Read from MongoDB | Semaines 3-4 | API lit depuis MongoDB, fichiers en backup | Moyen |
| Phase 3 — Deprecate Files | Semaine 5+ | Suppression du système fichier | Irréversible |
---
## Prérequis
### Infrastructure
- MongoDB 5.0+ (pas besoin de replica set — le système utilise un EventEmitter in-process, pas de change streams)
- Espace disque MongoDB : prévoir ~500 Mo pour 10 000 devices actifs avec 5 000 messages max chacun
- L'application adam-acs doit être redémarrée après la migration de base
### Variables d'environnement
```bash
# Feature flags (déjà présents dans config/exchange_store.ts)
FEATURE_EXCHANGE_PERSISTENCE=true # Active les écritures MongoDB
FEATURE_SSE_ENABLED=true # Active le streaming SSE
FEATURE_EXCHANGE_API_SOURCE=mongodb # Source des données API (mongodb | file)
# Configuration optionnelle
EXCHANGE_STORE_MAX_MESSAGES=5000 # Cap messages par device
EXCHANGE_STORE_TTL_SECONDS=86400 # TTL 24h
EXCHANGE_STORE_READ_TIMEOUT_MS=5000 # Timeout requêtes API
```
---
## Phase 1 : Dual-Write (Semaines 1-2)
### Objectif
Écrire simultanément dans les deux systèmes (fichiers ET MongoDB) pour valider la fiabilité du nouveau système sans risque de perte.
### 1.1 Exécuter la migration MongoDB
La migration crée la collection `cwmp_exchanges` et ses index :
```bash
# Exécuter la migration
node ace migration:run --connection=mongodb
```
Cela exécute `database/mongo_migrations/011_create_cwmp_exchanges_collection.ts` qui crée :
- Collection `cwmp_exchanges` avec 3 index :
- `{ deviceId: 1, timestamp: 1 }` — requêtes par device
- `{ deviceId: 1, sequenceNumber: 1 }` (unique) — numérotation séquentielle et reconnexion SSE
- `{ createdAt: 1 }` (TTL: 86400s) — nettoyage automatique après 24h
- Collection `cwmp_exchange_counters` — compteurs atomiques de séquence
### 1.2 Vérifier les index
```bash
# Via mongosh
mongosh --eval "
db.cwmp_exchanges.getIndexes().forEach(idx => {
print(idx.name + ': ' + JSON.stringify(idx.key))
})
"
```
Résultat attendu :
```
_id_: {"_id":1}
idx_deviceId_timestamp: {"deviceId":1,"timestamp":1}
idx_deviceId_sequenceNumber: {"deviceId":1,"sequenceNumber":1}
idx_createdAt_ttl: {"createdAt":1}
```
### 1.3 Activer le dual-write
Le dual-write est déjà implémenté dans `CwmpLoggerMiddleware`. Vérifier les feature flags :
```bash
# .env — Phase 1
FEATURE_EXCHANGE_PERSISTENCE=true
FEATURE_SSE_ENABLED=true
FEATURE_EXCHANGE_API_SOURCE=file # GARDER 'file' en Phase 1
```
Le middleware écrit dans les deux systèmes :
```typescript
// app/middleware/cwmp_logger_middleware.ts (extrait)
if (isTraced && deviceId) {
// Nouveau système : MongoDB (fire-and-forget)
exchangeStore.persistExchange({ deviceId, direction, sessionId, rawXml })
.catch(() => {})
// Ancien système : fichiers (gardé pour rollback)
traceService.writeExchange(deviceId, direction, sessionId, prettyXml)
}
```
### 1.4 Redémarrer l'application
```bash
docker compose build app
docker compose up -d app
```
### 1.5 Vérifier le fonctionnement
Activer le trace sur un device et déclencher un Inform :
```bash
# Vérifier que MongoDB reçoit les données
mongosh --eval "db.cwmp_exchanges.countDocuments({})"
# Vérifier les derniers échanges
mongosh --eval "
db.cwmp_exchanges.find({}).sort({timestamp: -1}).limit(3).forEach(doc => {
print(doc.deviceId + ' | ' + doc.direction + ' | ' + doc.cwmpMethod)
})
"
```
### 1.6 Vérification de cohérence (Dual-Write)
Pendant la Phase 1, vérifier régulièrement que les deux systèmes restent synchronisés :
#### Script de comparaison
```bash
#!/bin/bash
# scripts/verify_dual_write.sh
# Compare le nombre d'échanges entre fichiers et MongoDB pour chaque device tracé
DEVICE_ID=$1
if [ -z "$DEVICE_ID" ]; then
echo "Usage: $0 <deviceId>"
exit 1
fi
# Compteur fichier (nombre de séparateurs '═' = nombre d'échanges)
FILE_COUNT=$(grep -c '═════' "logs/tr069/${DEVICE_ID}.log" 2>/dev/null || echo "0")
# Compteur MongoDB
MONGO_COUNT=$(mongosh --quiet --eval "db.cwmp_exchanges.countDocuments({deviceId: '${DEVICE_ID}'})")
echo "Device: ${DEVICE_ID}"
echo " Fichiers : ${FILE_COUNT} échanges"
echo " MongoDB : ${MONGO_COUNT} échanges"
if [ "$FILE_COUNT" != "$MONGO_COUNT" ]; then
DIFF=$((FILE_COUNT - MONGO_COUNT))
echo " ⚠️ Écart : ${DIFF} messages"
if [ "${DIFF#-}" -gt $((FILE_COUNT / 20)) ]; then
echo " 🚨 Écart > 5% — Investigation requise !"
fi
else
echo " ✅ Cohérent"
fi
```
#### Critères d'acceptation Phase 1
| Critère | Seuil | Action si dépassé |
|---------|-------|-------------------|
| Écart fichier/MongoDB | < 5% | Vérifier les logs d'erreur ExchangeStore |
| Erreurs de persistance | < 0.1% | Vérifier la connectivité MongoDB |
| Latence MongoDB p95 | < 100ms | Vérifier la charge et les index |
| Messages perdus (critiques) | 0 après retries | Vérifier les logs de retry exhaustion |
#### Durée recommandée
Maintenir le dual-write pendant **minimum 1 semaine** avec des vérifications quotidiennes. Passer en Phase 2 uniquement si les critères ci-dessus sont respectés de manière constante.
---
## Phase 2 : Read from MongoDB (Semaines 3-4)
### Objectif
Basculer la lecture des données vers MongoDB tout en gardant les fichiers en écriture backup.
### 2.1 Changer la source de lecture API
```bash
# .env — Phase 2
FEATURE_EXCHANGE_PERSISTENCE=true
FEATURE_SSE_ENABLED=true
FEATURE_EXCHANGE_API_SOURCE=mongodb # ← Changer de 'file' à 'mongodb'
```
### 2.2 Redémarrer l'application
```bash
docker compose restart app
```
### 2.3 Vérifier le fonctionnement
```bash
# Vérifier que l'API retourne des données depuis MongoDB
curl -s "http://localhost:8080/api/v1/tr069-trace/<DEVICE_ID>/exchanges?limit=5" | \
python3 -c "
import sys, json
data = json.load(sys.stdin)
print(f\"Source: MongoDB\")
print(f\"Exchanges: {len(data.get('exchanges', []))} messages\")
print(f\"Metadata: {data.get('metadata', {})}\")
"
```
### 2.4 Vérifier le SSE
```bash
# Ouvrir une connexion SSE (ctrl+C pour arrêter)
curl -N -H "Accept: text/event-stream" \
"http://localhost:8080/api/v1/tr069-trace/<DEVICE_ID>/exchanges/stream"
```
Déclencher un Inform sur le device tracé et vérifier qu'un événement SSE arrive en temps réel.
### 2.5 Vérifier le fallback
Si MongoDB est indisponible, le frontend doit retomber sur les fichiers :
```typescript
// Logique dans DeviceDetail.vue
const exchanges = await api.getExchanges(deviceId)
.catch(() => legacyService.readExchanges(deviceId))
```
### 2.6 Critères de passage Phase 2 → Phase 3
| Critère | Seuil | Vérifié |
|---------|-------|---------|
| API MongoDB fonctionne sans erreur | 48h continues | ☐ |
| SSE pousse les événements en < 500ms | p95 vérifié | ☐ |
| Aucune perte de message critique | 0 sur 48h | ☐ |
| Reconnexion SSE (Last-Event-ID) valide | Testé manuellement | ☐ |
| Purge (DELETE) fonctionne | 204 retourné | ☐ |
---
## Phase 3 : Deprecate Old System (Semaine 5+)
### Objectif
Supprimer le système fichier une fois que MongoDB est validé en production.
### 3.1 Supprimer le dual-write du middleware
Dans `app/middleware/cwmp_logger_middleware.ts`, retirer les appels au système fichier :
```typescript
// AVANT (dual-write)
if (isTraced && deviceId) {
exchangeStore.persistExchange({ deviceId, direction, sessionId, rawXml }).catch(() => {})
traceService.writeExchange(deviceId, direction, sessionId, prettyXml) // ← SUPPRIMER
}
// APRÈS (MongoDB uniquement)
if (isTraced && deviceId) {
exchangeStore.persistExchange({ deviceId, direction, sessionId, rawXml }).catch(() => {})
}
```
### 3.2 Supprimer les dépendances obsolètes
1. Retirer l'import `xml-formatter` du middleware (le formatage n'est plus nécessaire côté persistance)
2. Supprimer les appels à `Tr069TraceService.writeExchange()` dans le middleware
3. **NE PAS** supprimer `Tr069TraceService` lui-même — il est encore utilisé pour gérer l'état trace (start/stop)
### 3.3 Nettoyer les fichiers de logs
```bash
# Archiver les anciens logs avant suppression
tar -czf logs/tr069-archive-$(date +%Y%m%d).tar.gz logs/tr069/
rm -rf logs/tr069/*.log*
```
### 3.4 Mise à jour de la configuration
```bash
# .env — Phase 3 (état final)
FEATURE_EXCHANGE_PERSISTENCE=true
FEATURE_SSE_ENABLED=true
FEATURE_EXCHANGE_API_SOURCE=mongodb
```
### 3.5 Vérification finale
```bash
# Vérifier qu'aucun fichier .log n'est créé
ls -la logs/tr069/
# Vérifier que le système fonctionne uniquement via MongoDB
curl -s "http://localhost:8080/api/v1/health/tr069-exchanges" | python3 -m json.tool
```
---
## Procédures de Rollback
### Rollback Phase 1 → Système fichier seul
**Situation :** MongoDB pose problème, il faut revenir au système fichier uniquement.
```bash
# 1. Désactiver la persistance MongoDB
FEATURE_EXCHANGE_PERSISTENCE=false
# 2. Redémarrer
docker compose restart app
# 3. Vérifier que les fichiers continuent d'être écrits
ls -la logs/tr069/
```
**Impact :** Les données déjà en MongoDB restent accessibles mais ne sont plus alimentées. Le SSE ne fonctionne plus. L'UI retombe sur les fichiers.
**Temps de rollback :** < 2 minutes (changement d'env + restart)
### Rollback Phase 2 → Phase 1 (Dual-Write)
**Situation :** L'API MongoDB a des problèmes, revenir au dual-write avec lecture fichier.
```bash
# 1. Changer la source API
FEATURE_EXCHANGE_API_SOURCE=file
# 2. Redémarrer
docker compose restart app
```
**Impact :** L'API lit les fichiers au lieu de MongoDB. Le dual-write continue. Aucune perte de données.
**Temps de rollback :** < 2 minutes
### Rollback Phase 3 → Phase 2
**Situation :** Après suppression du dual-write, MongoDB pose problème.
**⚠️ ATTENTION : Ce rollback nécessite un redéploiement du code.**
1. Revert du commit qui a supprimé le dual-write dans `CwmpLoggerMiddleware`
2. Redéployer l'application
3. Vérifier que les fichiers sont à nouveau écrits
```bash
# Identifier le commit de suppression du dual-write
git log --oneline -- app/middleware/cwmp_logger_middleware.ts
# Revert
git revert <commit-hash>
docker compose build app
docker compose up -d app
```
**Impact :** Nécessite un redéploiement (~5 minutes). Les échanges entre la suppression et le rollback ne sont PAS dans les fichiers.
**Temps de rollback :** 5-10 minutes
### Rollback SSE uniquement
**Situation :** Le SSE cause des problèmes (connexions, mémoire) mais MongoDB est stable.
```bash
# Désactiver uniquement le SSE
FEATURE_SSE_ENABLED=false
# Redémarrer
docker compose restart app
```
**Impact :** Le frontend bascule automatiquement en REST polling (toutes les 5 secondes). Les données MongoDB sont toujours disponibles. Pas de perte.
### Rollback complet (retour système fichier)
**Situation :** Problème majeur, tout désactiver.
```bash
# Tout désactiver
FEATURE_EXCHANGE_PERSISTENCE=false
FEATURE_SSE_ENABLED=false
FEATURE_EXCHANGE_API_SOURCE=file
# Redémarrer
docker compose restart app
```
**Impact :** Retour complet au système fichier. MongoDB n'est plus utilisé. L'UI affiche les logs comme avant la migration.
---
## Migration des données historiques (optionnel)
Si vous souhaitez importer les logs fichier existants dans MongoDB, utilisez le script ci-dessous. Cette étape est **optionnelle** car les anciens logs disparaîtront naturellement via le TTL 24h.
### Script d'import
```typescript
// scripts/migrate_file_logs_to_mongodb.ts
import { readFileSync, readdirSync } from 'node:fs'
import { join } from 'node:path'
import { getMongoDb } from '#providers/mongodb_provider'
const LOG_DIR = join(process.cwd(), 'logs', 'tr069')
const SEPARATOR = '═'.repeat(80)
interface ParsedEntry {
deviceId: string
timestamp: string
direction: 'CPE→ACS' | 'ACS→CPE'
sessionId: string
rawXml: string
}
function parseLogFile(deviceId: string, content: string): ParsedEntry[] {
const entries: ParsedEntry[] = []
const blocks = content.split(SEPARATOR).filter((b) => b.trim())
for (let i = 0; i < blocks.length - 1; i += 2) {
const header = blocks[i].trim()
const xml = blocks[i + 1]?.trim() || ''
// Parse header: [2025-01-15T10:30:00.123Z] CPE→ACS | 10.0.0.1:54321->192.168.1.1:8080
const headerMatch = header.match(
/\[(.+?)\]\s+(CPE→ACS|ACS→CPE)\s+\|\s+(.+)/
)
if (!headerMatch) continue
entries.push({
deviceId,
timestamp: headerMatch[1],
direction: headerMatch[2] as 'CPE→ACS' | 'ACS→CPE',
sessionId: headerMatch[3],
rawXml: xml,
})
}
return entries
}
async function migrateAll(): Promise<void> {
const db = getMongoDb()
const collection = db.collection('cwmp_exchanges')
const counters = db.collection('cwmp_exchange_counters')
const files = readdirSync(LOG_DIR).filter((f) => f.endsWith('.log'))
let totalMigrated = 0
for (const file of files) {
const deviceId = file.replace('.log', '')
const content = readFileSync(join(LOG_DIR, file), 'utf-8')
const entries = parseLogFile(deviceId, content)
if (entries.length === 0) continue
// Get or initialize sequence counter
const counterResult = await counters.findOneAndUpdate(
{ _id: deviceId as any },
{ $inc: { seq: entries.length } },
{ upsert: true, returnDocument: 'after' }
)
const startSeq = (counterResult!.seq as number) - entries.length + 1
// Build documents
const docs = entries.map((entry, idx) => ({
...entry,
sequenceNumber: startSeq + idx,
cwmpMethod: extractMethod(entry.rawXml),
createdAt: new Date(entry.timestamp),
}))
// Bulk insert
await collection.insertMany(docs, { ordered: false }).catch((err) => {
console.warn(` ⚠️ Duplicates ignored for ${deviceId}: ${err.message}`)
})
totalMigrated += docs.length
console.log(` ✅ ${deviceId}: ${docs.length} échanges migrés`)
}
console.log(`\n📊 Total: ${totalMigrated} échanges migrés depuis ${files.length} fichiers`)
}
function extractMethod(xml: string): string {
if (!xml || xml.trim() === '') return 'Empty'
const match = xml.match(/<cwmp:(\w+)[\s/>]/)
return match ? match[1] : 'Unknown'
}
migrateAll().catch(console.error)
```
### Exécution
```bash
# Depuis la racine du projet
npx ts-node scripts/migrate_file_logs_to_mongodb.ts
```
**Notes :**
- Le script est idempotent : les doublons sont ignorés (grâce à l'index unique deviceId + sequenceNumber)
- Les documents importés auront un `createdAt` basé sur le timestamp du log, donc ils seront supprimés par le TTL 24h si ils datent de plus de 24 heures
- Pour conserver les données historiques plus longtemps, ajustez temporairement `EXCHANGE_STORE_TTL_SECONDS`

## FAQ
### Que se passe-t-il si MongoDB tombe pendant le dual-write ?
Les écritures MongoDB échouent silencieusement (fire-and-forget). Le système fichier continue normalement. Les messages critiques sont retentés 3 fois avec backoff exponentiel (1s, 2s, 4s) avant d'être abandonnés. La session CWMP n'est jamais interrompue.
### Le TTL va-t-il supprimer des données pendant la migration ?
Oui. Le TTL de 24h s'applique dès la création de l'index. Si vous importez des logs historiques de plus de 24h, ils seront supprimés par le TTL monitor MongoDB (qui tourne ~toutes les 60 secondes). Augmentez temporairement `EXCHANGE_STORE_TTL_SECONDS` si nécessaire.
### Puis-je migrer les données fichier vers MongoDB ?
Oui, voir la section "Migration des données historiques". C'est optionnel car le système fonctionne immédiatement avec les nouveaux échanges. Les anciens logs fichier restent lisibles via `FEATURE_EXCHANGE_API_SOURCE=file`.
### Combien d'espace MongoDB est nécessaire ?
Estimation : ~1 Ko par échange (métadonnées) + taille du XML brut (typiquement 2-50 Ko). Avec le cap de 5 000 messages par device et le TTL 24h, la croissance est bornée. Pour 100 devices tracés simultanément : ~500 Mo maximum.
### Le dual-write a-t-il un impact sur les performances CWMP ?
Non. Les écritures MongoDB sont fire-and-forget (`catch(() => {})`) et ne bloquent jamais le traitement CWMP. En cas de lenteur MongoDB, le middleware continue sans attendre.

# Alerting Rules — TR-069 Exchange Viewer
## Overview
Ce document décrit les règles d'alerte configurées pour le système TR-069 Exchange Viewer. Chaque règle définit un seuil critique, les conditions de déclenchement, l'impact attendu et la procédure d'escalade associée.
Les métriques sont exposées via le endpoint `/api/v1/health/tr069-exchanges` et les logs structurés JSON.
---
## Alert 1: SSE Active Connections > 100
### Seuil
| Métrique | Condition | Sévérité |
|----------|-----------|----------|
| `sse.active_connections` | > 100 connexions simultanées | **Warning** |
| `sse.active_connections` | > 200 connexions simultanées | **Critical** |
### Description
Un nombre élevé de connexions SSE simultanées indique une charge serveur importante. Chaque connexion SSE maintient un socket HTTP ouvert et un listener EventEmitter en mémoire. Au-delà de 100 connexions, le serveur risque une dégradation de performance (latence accrue, consommation mémoire excessive).
### Causes possibles
- Pic d'activité : de nombreux opérateurs tracent des devices simultanément
- Fuite de connexions : les clients ne ferment pas correctement les connexions EventSource (navigation sans cleanup)
- Reconnection storm : perte réseau transitoire provoquant la reconnexion simultanée de tous les clients
- Bug client : boucle de reconnexion infinie (EventSource retry sans backoff)
### Impact
- Augmentation de la consommation mémoire du processus Node.js
- Latence accrue sur les push SSE (chaque nouveau message est dispatché à N listeners)
- Risque d'épuisement des file descriptors (limite OS)
- Dégradation possible du traitement CWMP si le thread principal est saturé
### Détection
```json
// GET /api/v1/health/tr069-exchanges
{
"sse": {
"active_connections": 142,
"reconnections_1h": 56
}
}
```
Logs structurés :
```json
{ "level": "warn", "msg": "SSE connection count high", "active_connections": 142, "threshold": 100 }
```
### Procédure de résolution
1. **Vérifier** le nombre de connexions actives via le health check endpoint
2. **Identifier** les devices avec le plus de connexions (logs : `sse.connect` events par deviceId)
3. **Vérifier** si des connexions zombies existent (connexions ouvertes sans activité > 5 minutes)
4. **Appliquer** les timeouts serveur : les connexions inactives sont fermées après 5 min, les absolues après 2h
5. **Si le problème persiste** : redémarrer le service pour forcer la fermeture de toutes les connexions SSE
### Escalade
| Durée | Action |
|-------|--------|
| 0-5 min | Monitoring automatique, pas d'action |
| 5-15 min (Warning) | Vérifier les logs, identifier la cause |
| > 15 min (Warning) | Notifier l'équipe Dev via Slack #adam-acs-alerts |
| Immédiat (Critical > 200) | Notifier l'équipe Dev + Ops, envisager un restart |
| > 30 min (Critical) | Activer le feature flag `FEATURE_SSE_ENABLED=false` (fallback REST polling) |
---
## Alert 2: MongoDB Write Latency p95 > 100ms
### Seuil
| Métrique | Condition | Sévérité |
|----------|-----------|----------|
| `mongodb.write_latency_p95` | > 100ms | **Warning** |
| `mongodb.write_latency_p95` | > 500ms | **Critical** |
| `mongodb.write_latency_p99` | > 1000ms | **Critical** |
### Description
La latence d'écriture MongoDB au percentile 95 reflète la performance de persistance des échanges CWMP. Au-delà de 100ms (p95), les écritures commencent à s'accumuler, ce qui peut provoquer un retard dans la diffusion SSE et une pression mémoire sur le processus.
### Causes possibles
- Charge MongoDB élevée (autres opérations concurrentes, compaction, journalisation)
- Index manquant ou dégradé sur la collection `cwmp_exchanges`
- Disque I/O saturé sur le serveur MongoDB
- Collection `cwmp_exchanges` trop volumineuse (TTL cleanup en retard)
- Locks MongoDB : opérations bulk ou migrations en cours
### Impact
- Retard dans la diffusion SSE des nouveaux échanges (latence end-to-end augmentée)
- Activation des retries pour les messages critiques (backoff 1s, 2s, 4s)
- En cas de timeout persistant : perte potentielle de messages non-critiques (Empty, Unknown)
- Le traitement CWMP n'est jamais impacté (fire-and-forget)
### Détection
Logs structurés :
```json
{ "level": "warn", "msg": "MongoDB write slow", "collection": "cwmp_exchanges", "duration_ms": 145, "deviceId": "abc123", "cwmpMethod": "Inform" }
```
Métriques agrégées (via logs ou Prometheus) :
```
mongodb_write_latency_ms{collection="cwmp_exchanges", quantile="0.95"} 145
mongodb_write_latency_ms{collection="cwmp_exchanges", quantile="0.99"} 320
```
### Procédure de résolution
1. **Vérifier** l'état de MongoDB : `db.serverStatus()`, `db.currentOp()`
2. **Vérifier** les index de `cwmp_exchanges` :
```bash
mongosh --eval "db.cwmp_exchanges.getIndexes()"
```
3. **Vérifier** la taille de la collection et le nombre de documents :
```bash
mongosh --eval "db.cwmp_exchanges.stats()"
```
4. **Vérifier** le TTL cleanup (voir Alert 4)
5. **Si les index sont manquants** : recréer via la migration ou manuellement :
```bash
mongosh --eval "db.cwmp_exchanges.createIndex({deviceId:1, timestamp:1})"
mongosh --eval "db.cwmp_exchanges.createIndex({deviceId:1, sequenceNumber:1}, {unique:true})"
mongosh --eval "db.cwmp_exchanges.createIndex({createdAt:1}, {expireAfterSeconds:86400})"
```
6. **Si la charge est transitoire** : attendre la stabilisation (compaction terminée, etc.)
### Escalade

## Alert 3: Message Loss Rate > 0.1%
### Seuil
| Métrique | Condition | Sévérité |
|----------|-----------|----------|
| `exchange.loss_rate` | > 0.1% (1 message sur 1000) | **Critical** |
| `exchange.loss_rate` | > 1.0% (1 message sur 100) | **Urgent** |
### Description
Le taux de perte de messages représente le pourcentage de messages CWMP capturés par le middleware mais non persistés en MongoDB (après épuisement des retries pour les critiques, ou discard immédiat pour les non-critiques). Un taux > 0.1% indique des défaillances critiques du backend de persistance.
### Causes possibles
- Défaillance MongoDB : connexion perdue, timeout, disque plein
- Retry exhaustion : 3 retries échoués consécutivement pour les messages critiques
- Erreur dans le service `ExchangeStoreService` (bug, exception non catchée)
- Saturation de la collection (cap à 5000 messages avec suppression simultanée)
- Problème réseau entre l'application et MongoDB
### Impact
- Trous dans l'historique des échanges visibles dans le Sequence Viewer
- Les opérateurs voient des séquences incomplètes, rendant le debug difficile
- Les messages critiques (Inform, SetParameterValues) perdus représentent une perte d'observabilité sur les actions CPE
### Détection
Logs structurés :
```json
{ "level": "error", "msg": "Exchange persistence failed after retries", "deviceId": "abc123", "cwmpMethod": "Inform", "retries": 3, "error": "MongoServerError: connection timeout" }
{ "level": "warn", "msg": "Non-critical exchange discarded", "deviceId": "abc123", "cwmpMethod": "Empty", "error": "MongoServerError: connection timeout" }
```
Calcul du taux de perte :
```
loss_rate = (messages_discarded / messages_captured) * 100
```
### Procédure de résolution
1. **Vérifier** la connectivité MongoDB : health check endpoint, `mongosh` ping
2. **Vérifier** les logs d'erreur pour identifier le pattern de défaillance
3. **Vérifier** l'espace disque disponible sur le serveur MongoDB
4. **Vérifier** que le TTL cleanup fonctionne (pas d'accumulation illimitée)
5. **Si MongoDB est injoignable** : vérifier le réseau, le service mongod, les limites de connexions
6. **Si MongoDB est surchargé** : identifier les opérations concurrentes, envisager un throttle
### Escalade
| Durée | Action |
|-------|--------|
| Immédiat (> 0.1%) | **Alerte critique** — Notifier l'équipe Dev immédiatement |
| 0-5 min | Diagnostic rapide : MongoDB up? Index OK? Disk space? |
| 5-15 min | Notifier Dev + Ops, vérifier infrastructure MongoDB |
| > 15 min | Escalade management, envisager rollback vers fichiers |
| Immédiat (> 1.0%) | **Alerte urgente** — Activer `FEATURE_EXCHANGE_PERSISTENCE=false`, diagnostic prioritaire |

## Alert 4: TTL Cleanup Lag > 1 Hour
### Seuil
| Métrique | Condition | Sévérité |
|----------|-----------|----------|
| `exchange.ttl_cleanup_lag` | > 1 heure | **Warning** |
| `exchange.ttl_cleanup_lag` | > 6 heures | **Critical** |
### Description
L'index TTL sur le champ `createdAt` (expire après 86400 secondes = 24h) est géré par un thread interne MongoDB qui s'exécute toutes les 60 secondes. Si le cleanup prend du retard, des documents expirés s'accumulent, augmentant la taille de la collection et dégradant les performances de requête.
Le "lag" est mesuré comme la différence entre le plus ancien document présent dans la collection et son heure d'expiration théorique (createdAt + 24h).
### Causes possibles
- MongoDB TTL monitor surchargé (collection très volumineuse, beaucoup de documents à supprimer)
- Index TTL supprimé ou corrompu
- MongoDB en mode de maintenance (locks, compaction)
- Charge élevée sur le serveur empêchant le thread TTL de s'exécuter
- Bug dans la configuration du TTL (mauvais champ, mauvaise valeur `expireAfterSeconds`)
### Impact
- Croissance non contrôlée de la collection `cwmp_exchanges`
- Dégradation progressive des performances de lecture (scans plus larges)
- Consommation disque accrue
- Potentiel dépassement des limites de stockage
### Détection
Vérification manuelle du lag :
```bash
# Trouver le document le plus ancien
mongosh --eval "
const oldest = db.cwmp_exchanges.find().sort({createdAt: 1}).limit(1).toArray()[0];
if (oldest) {
const expectedExpiry = new Date(oldest.createdAt.getTime() + 86400000);
const lag = Date.now() - expectedExpiry.getTime();
print('Oldest createdAt:', oldest.createdAt);
print('Expected expiry:', expectedExpiry);
print('Lag (ms):', Math.max(0, lag));
print('Lag (hours):', Math.max(0, lag / 3600000).toFixed(2));
} else {
print('Collection empty');
}
"
```
Vérification de l'index TTL :
```bash
mongosh --eval "
const indexes = db.cwmp_exchanges.getIndexes();
const ttlIndex = indexes.find(i => i.expireAfterSeconds !== undefined);
if (ttlIndex) {
print('TTL index found:', JSON.stringify(ttlIndex));
} else {
print('WARNING: No TTL index found!');
}
"
```
### Procédure de résolution
1. **Vérifier** que l'index TTL existe et est correctement configuré :
```bash
mongosh --eval "db.cwmp_exchanges.getIndexes()"
```
L'index attendu : `{ "createdAt": 1 }` avec `expireAfterSeconds: 86400`
2. **Si l'index TTL est manquant** — le recréer :
```bash
mongosh --eval "db.cwmp_exchanges.createIndex({createdAt: 1}, {expireAfterSeconds: 86400})"
```
3. **Si l'index existe mais le cleanup est en retard** :
- Vérifier la charge MongoDB : `db.serverStatus().metrics.ttl`
- Vérifier si un grand nombre de documents doivent être supprimés d'un coup
- Envisager un nettoyage manuel des plus anciens documents :
```bash
mongosh --eval "
const cutoff = new Date(Date.now() - 86400000);
const result = db.cwmp_exchanges.deleteMany({createdAt: {$lt: cutoff}});
print('Deleted:', result.deletedCount);
"
```
4. **Si MongoDB est en maintenance** : attendre la fin de l'opération, surveiller la reprise du TTL
### Escalade
| Durée | Action |
|-------|--------|
| 0-1h | Monitoring automatique (TTL thread cycle = 60s, léger retard normal) |
| 1-3h (Warning) | Vérifier l'existence de l'index TTL, vérifier la charge MongoDB |
| 3-6h (Warning) | Notifier l'équipe Dev, envisager un nettoyage manuel |
| > 6h (Critical) | Notifier Dev + DBA, nettoyage manuel obligatoire, diagnostic approfondi |
| > 24h | Escalade management — la collection grandit sans limite |

## Brand & Style
This design system is engineered for high-performance network analysis and protocol monitoring. The brand personality is rooted in **precision, neutrality, and clarity**. It avoids decorative flourishes to prioritize the rapid interpretation of complex data structures.
The visual style is a blend of **Minimalism** and **Modern Corporate** aesthetics. It utilizes a spacious layout to reduce the cognitive load inherent in dense data environments. The interface conveys reliability through a systematic application of subtle borders and high-contrast typography, ensuring that critical network events are immediately visible.
## Colors
The palette is anchored in **Slate and Zinc** neutrals to provide a professional, calm environment for long-term monitoring.
* **Primary (Slate 950):** Used for core navigation, high-level headers, and text to ensure maximum contrast.
* **Neutral (Slate/Zinc):** Used for structural elements, secondary text, and inactive states.
* **Flow Accents:** Semantic colors are reserved for directional data. **Teal (ACS -> CPE)** and **Indigo (CPE -> ACS)** allow engineers to visually parse the direction of TR-069 traffic at a glance without reading text labels.
* **Success/Error:** Traditional Green and Red are used sparingly for status indicators and connection states.
## Typography
This design system utilizes a dual-font strategy. **Inter** is the workhorse for the UI, chosen for its exceptional legibility in small sizes and high-density layouts. **JetBrains Mono** is utilized exclusively for technical data, including XML, JSON payloads, and packet hex dumps.
Headlines use tighter letter spacing for a more authoritative look, while labels utilize uppercase styling and increased tracking for clear categorization in sidebars and table headers. Monospaced text is rendered with a slightly smaller font size than body text to accommodate long lines of code without excessive wrapping.
## Layout & Spacing
The layout follows a **Hybrid Grid** model. Navigation and property inspectors use fixed-width sidebars, while the main content area—typically containing packet logs or traffic graphs—uses a **Fluid Grid** to maximize horizontal real estate.
### Breakpoints
* **Desktop (1280px+):** 12-column fluid grid, 24px margins.
* **Tablet (768px - 1279px):** 8-column fluid grid, 16px margins. Sidebar collapses to icons.
* **Mobile (<767px):** 4-column fluid grid, 12px margins. Horizontal scrolling enabled for data tables.
Spacing is based on a **4px base unit**. Component internals use 8px or 12px increments to maintain a compact, "instrumental" feel without appearing cluttered.
## Elevation & Depth
To maintain a technical and minimalist aesthetic, this design system avoids heavy shadows. Instead, it relies on **Tonal Layers** and **Low-Contrast Outlines**.
* **Background (Level 0):** Slate-50. The base canvas.
* **Surface (Level 1):** White. Primary cards and panels.
* **Active/Overlay (Level 2):** White with a subtle 1px border in Slate-200 and a very soft, high-diffusion shadow (4px blur, 2% opacity) to indicate temporary elements like tooltips or dropdowns.
Visual separation between adjacent panels is achieved via 1px solid borders in Slate-200 rather than elevation, ensuring the UI remains crisp and "flat."
## Shapes
The shape language is **Soft (Level 1)**. A 4px radius is applied to buttons, input fields, and panels. This subtle rounding provides a modern touch without sacrificing the professional, rigid structure required for a technical tool.
Status indicators (pills) use a slightly larger 12px radius to distinguish them from interactive buttons, while data visualization bars use sharp 2px corners for maximum precision.
## Components
### Buttons
Primary buttons use the Slate-950 background with white text. Ghost buttons (transparent background with Slate-200 borders) are preferred for secondary actions to keep the focus on the data.
### Packet Log Entries
Logs must use a zebra-stripe pattern (White / Slate-50) for horizontal tracking. The "Flow Direction" is indicated by a 4px vertical accent bar on the far left of the row (Teal or Indigo).
### Input Fields
Fields use a 1px Slate-200 border. On focus, the border transitions to Slate-900. Labels are always positioned above the input in the `label-md` style for clarity.
### Data Displays (Code Blocks)
XML/JSON payloads are wrapped in containers with a Slate-50 background and a 1px border. They use `mono-md` typography with syntax highlighting that mirrors the flow colors (Teal for tags, Indigo for values).
### Chips & Badges
Used for protocol methods (e.g., `Inform`, `GetParameterValues`). These are small, low-contrast components (Slate-100 background) to avoid competing with the flow direction accents.

---
## 1. Déconnexions SSE
### 1.1 Causes courantes
| Cause | Symptôme | Fréquence |
|-------|----------|-----------|
| **Timeout d'inactivité (5 min)** | Déconnexion après 5 minutes sans nouvel échange | Normal — par design |
| **Timeout absolu (2 h)** | Déconnexion après 2 heures de connexion continue | Normal — par design |
| **Proxy/reverse-proxy buffering** | Messages SSE arrivent en burst au lieu de temps réel | Courant avec nginx |
| **Perte réseau** | Indicateur "disconnected" dans le viewer | Variable |
| **SSE désactivé (feature flag)** | Erreur 503 à la connexion SSE | Intentionnel |
| **Device non tracé** | Erreur 404 à la connexion SSE | Erreur utilisateur |
### 1.2 Solutions
#### Timeout d'inactivité / absolu
Le système est conçu pour fermer les connexions inactives. Le client se reconnecte automatiquement via le mécanisme `Last-Event-ID` — aucun message n'est perdu.
Pour ajuster les timeouts :
```bash
# Augmenter le timeout d'inactivité (défaut: 300000ms = 5 min)
EXCHANGE_STORE_SSE_INACTIVITY_TIMEOUT_MS=600000
# Augmenter le timeout absolu (défaut: 7200000ms = 2h)
EXCHANGE_STORE_SSE_ABSOLUTE_TIMEOUT_MS=14400000
```
#### Proxy/reverse-proxy buffering
Si un reverse-proxy (nginx, HAProxy) est en place, il peut bufferiser les réponses SSE. Le header `X-Accel-Buffering: no` est déjà envoyé par le serveur, mais vérifiez aussi la configuration nginx :
```nginx
location /api/v1/tr069-trace/ {
proxy_buffering off;
proxy_cache off;
proxy_set_header Connection '';
proxy_http_version 1.1;
chunked_transfer_encoding off;
}
```
#### Client qui ne se reconnecte pas
Le composable `useExchangeStream` utilise l'`EventSource` natif avec retry automatique (3 secondes par défaut). Si la reconnexion ne fonctionne pas :
1. Vérifiez que le device est toujours en trace active
2. Vérifiez les logs serveur pour des erreurs 404 ou 503
3. Vérifiez la valeur `retry` dans la configuration SSE :
```bash
# Intervalle de reconnexion envoyé au client (défaut: 3000ms)
EXCHANGE_STORE_SSE_RETRY_INTERVAL_MS=3000
```
### 1.3 Diagnostic dans les logs
Cherchez les entrées `[SSE]` dans les logs applicatifs :
```bash
docker compose logs app | grep '\[SSE\]'
```
Messages attendus :
- `[SSE] Connection closed { deviceId: "...", reason: "inactivity" }` — timeout normal
- `[SSE] Connection closed { deviceId: "...", reason: "absolute" }` — timeout absolu normal
- `[SSE] Connection closed { deviceId: "...", reason: "client_disconnect" }` — client a fermé
- `[SSE] Error fetching missed exchanges for reconnection` — problème MongoDB lors du rattrapage
---
## 2. Timeouts MongoDB et récupération
### 2.1 Scénarios de timeout
| Scénario | Impact | Comportement |
|----------|--------|--------------|
| **Write timeout (persistance)** | Message potentiellement perdu | Retry (critique) ou discard (non-critique) |
| **Read timeout (API >5s)** | Résultats partiels retournés | `isTruncated: true` dans la réponse |
| **Connection lost** | Toutes les opérations échouent | Les sessions CWMP continuent sans log |
### 2.2 Write timeout — Retry automatique
Le `ExchangeStoreService` gère les échecs d'écriture selon la criticité du message :
**Messages critiques** (Inform, GetParameterValues, SetParameterValuesResponse, Fault, etc.) :
- 3 tentatives avec backoff exponentiel : 1s, 2s, 4s
- Si toutes échouent : log error + discard (session CWMP non impactée)
**Messages non-critiques** (Empty, Unknown) :
- Aucun retry — discard immédiat + log warning
Vérifier les échecs de retry :
```bash
docker compose logs app | grep '\[ExchangeStore\] All retries exhausted'
docker compose logs app | grep '\[ExchangeStore\] Critical message persistence failed'
```
Pour ajuster la politique de retry :
```bash
# Nombre max de tentatives (défaut: 3)
EXCHANGE_STORE_RETRY_MAX_ATTEMPTS=3
# Délai de base en ms pour le backoff (défaut: 1000)
# Résultat : 1000ms, 2000ms, 4000ms
EXCHANGE_STORE_RETRY_BASE_DELAY_MS=1000
```
### 2.3 Read timeout — Résultats partiels
Si une requête API dépasse 5 secondes, le contrôleur retourne les résultats partiels avec un flag :
```json
{
"exchanges": [...],
"metadata": {
"isTruncated": true,
"total": 4500
}
}
```
**Causes courantes :**
- Index manquant sur `(deviceId, timestamp)` — voir section 4
- Trop de documents pour le device (proche du cap 5000)
- Charge MongoDB élevée (vérifier les métriques)
Pour ajuster le timeout de lecture :
```bash
# Timeout en ms (défaut: 5000)
EXCHANGE_STORE_READ_TIMEOUT_MS=5000
```
### 2.4 Vérifier la connectivité MongoDB
```bash
# Se connecter au shell MongoDB
docker compose exec mongodb mongosh
# Vérifier le statut
db.adminCommand({ serverStatus: 1 }).connections
# Vérifier la latence
db.adminCommand({ ping: 1 })
```
---
## 3. Diagnostic de perte de messages
### 3.1 Arbre de décision
```
Message manquant dans le viewer ?
│
├─ Le device est-il en trace ?
│ └─ Non → Activer la trace d'abord. Les messages ne sont PAS persistés hors trace.
│
├─ Le feature flag FEATURE_EXCHANGE_PERSISTENCE est-il à true ?
│ └─ Non → Activer la persistance : FEATURE_EXCHANGE_PERSISTENCE=true
│
├─ Le message apparaît-il dans MongoDB mais pas dans le viewer ?
│ └─ Oui → Problème SSE (voir section 1) ou problème frontend (voir section 5)
│
├─ Le message n'apparaît PAS dans MongoDB ?
│ ├─ Vérifier les logs de retry : grep "All retries exhausted"
│ ├─ Vérifier le cap (5000 messages) : les anciens messages sont supprimés
│ └─ Vérifier le TTL (24h) : les messages >24h sont auto-supprimés
│
└─ Message tronqué (XML incomplet) ?
└─ Le rawXml dépassait 2MB → grep "rawXml exceeds 2MB" dans les logs
```
### 3.2 Vérifier les messages en base
```bash
# Se connecter au shell MongoDB
docker compose exec mongodb mongosh
# Compter les messages pour un device
use adam_acs
db.cwmp_exchanges.countDocuments({ deviceId: "<DEVICE_ID>" })
# Voir les derniers messages
db.cwmp_exchanges.find({ deviceId: "<DEVICE_ID>" }).sort({ timestamp: -1 }).limit(5).pretty()
# Voir la séquence max (dernier message)
db.cwmp_exchange_counters.findOne({ _id: "<DEVICE_ID>" })
```
### 3.3 Vérifier les logs de persistance
```bash
# Chercher les erreurs de persistance
docker compose logs app | grep '\[ExchangeStore\]'
# Messages spécifiques
docker compose logs app | grep 'Failed to persist exchange'
docker compose logs app | grep 'Non-critical message persistence failed'
docker compose logs app | grep 'All retries exhausted'
docker compose logs app | grep 'Message cap enforced'
docker compose logs app | grep 'rawXml exceeds 2MB'
```
### 3.4 Message supprimé par le cap
Le système maintient un maximum de 5000 messages par device. Quand ce cap est dépassé, les messages les plus anciens sont supprimés.
```bash
# Vérifier si le cap a été atteint
docker compose logs app | grep 'Message cap enforced'
```
Pour ajuster le cap :
```bash
# Nombre max de messages par device (défaut: 5000)
EXCHANGE_STORE_MAX_MESSAGES=5000
```
### 3.5 Message supprimé par le TTL
MongoDB supprime automatiquement les documents dont `createdAt` dépasse 24 heures (via l'index TTL).
```bash
# Vérifier les documents les plus anciens
docker compose exec mongodb mongosh --eval "
use adam_acs;
db.cwmp_exchanges.find({}, { createdAt: 1, deviceId: 1 }).sort({ createdAt: 1 }).limit(3).pretty()
"
```
---
## 4. Vérification des index et du TTL
### 4.1 Lister les index existants
```bash
docker compose exec mongodb mongosh --eval "
use adam_acs;
db.cwmp_exchanges.getIndexes().forEach(idx => printjson(idx))
"
```
**Index attendus :**
| Nom | Champs | Options |
|-----|--------|---------|
| `_id_` | `{ _id: 1 }` | — |
| `idx_deviceId_timestamp` | `{ deviceId: 1, timestamp: 1 }` | — |
| `idx_deviceId_sequenceNumber` | `{ deviceId: 1, sequenceNumber: 1 }` | `unique: true` |
| `idx_createdAt_ttl` | `{ createdAt: 1 }` | `expireAfterSeconds: 86400` |
### 4.2 Vérifier l'index TTL
```bash
docker compose exec mongodb mongosh --eval "
use adam_acs;
const indexes = db.cwmp_exchanges.getIndexes();
const ttlIdx = indexes.find(i => i.name === 'idx_createdAt_ttl');
if (ttlIdx) {
print('TTL index OK — expireAfterSeconds:', ttlIdx.expireAfterSeconds);
} else {
print('ERREUR: TTL index manquant !');
}
"
```
### 4.3 Recréer les index manuellement (si manquants)
Si des index sont manquants après un incident :
```bash
docker compose exec mongodb mongosh --eval "
use adam_acs;
// Index composite (deviceId + timestamp)
db.cwmp_exchanges.createIndex(
{ deviceId: 1, timestamp: 1 },
{ name: 'idx_deviceId_timestamp' }
);
// Index unique (deviceId + sequenceNumber)
db.cwmp_exchanges.createIndex(
{ deviceId: 1, sequenceNumber: 1 },
{ unique: true, name: 'idx_deviceId_sequenceNumber' }
);
// Index TTL (24h)
db.cwmp_exchanges.createIndex(
{ createdAt: 1 },
{ expireAfterSeconds: 86400, name: 'idx_createdAt_ttl' }
);
print('Tous les index recréés.');
"
```
### 4.4 Vérifier le statut du TTL monitor
Le TTL monitor de MongoDB tourne par défaut toutes les 60 secondes. Pour vérifier qu'il fonctionne :
```bash
docker compose exec mongodb mongosh --eval "
const status = db.adminCommand({ serverStatus: 1 });
print('TTL deletedDocuments:', status.metrics.ttl.deletedDocuments);
print('TTL passes:', status.metrics.ttl.passes);
"
```
Si `passes` n'augmente pas, le TTL monitor pourrait être bloqué (rare, nécessite un restart MongoDB).
### 4.5 Modifier le TTL
Pour changer la durée du TTL sans recréer l'index :
```bash
docker compose exec mongodb mongosh --eval "
use adam_acs;
db.runCommand({
collMod: 'cwmp_exchanges',
index: {
name: 'idx_createdAt_ttl',
expireAfterSeconds: 172800 // 48h
}
});
"
```
N'oubliez pas de mettre à jour la variable d'environnement pour cohérence :
```bash
EXCHANGE_STORE_TTL_SECONDS=172800
```
### 4.6 Vérifier la collection counters
La collection `cwmp_exchange_counters` stocke les séquences atomiques par device :
```bash
docker compose exec mongodb mongosh --eval "
use adam_acs;
db.cwmp_exchange_counters.find().forEach(doc => {
print(doc._id, '→ seq:', doc.seq);
})
"
```
Si un compteur est incohérent avec les données réelles :
```bash
# Recalculer le max sequenceNumber pour un device
docker compose exec mongodb mongosh --eval "
use adam_acs;
const deviceId = '<DEVICE_ID>';
const maxSeq = db.cwmp_exchanges.find({ deviceId }).sort({ sequenceNumber: -1 }).limit(1).toArray();
if (maxSeq.length > 0) {
db.cwmp_exchange_counters.updateOne(
{ _id: deviceId },
{ \$set: { seq: maxSeq[0].sequenceNumber } }
);
print('Counter reset to', maxSeq[0].sequenceNumber);
}
"
```

## 5. Problèmes frontend (SequenceViewer)
### 5.1 Le viewer ne se connecte pas au SSE
**Causes possibles :**
1. Le device n'est pas en trace → activer la trace d'abord
2. Le feature flag `FEATURE_SSE_ENABLED` est à `false` → erreur 503
3. Problème CORS si accès depuis un domaine différent
**Diagnostic :** Ouvrir la console navigateur (F12) et chercher les erreurs EventSource.
### 5.2 Les messages ne s'affichent pas en temps réel
Si les messages arrivent dans MongoDB mais pas dans le viewer :
1. Vérifier l'indicateur de connexion : doit être "connected" (vert)
2. Si "disconnected" (rouge) : voir section 1
3. Si "paused" (jaune) : l'auto-scroll est désactivé car l'utilisateur a scrollé vers le haut — cliquer "Resume auto-scroll"
### 5.3 Performance lente avec beaucoup de messages
Le viewer utilise du virtual scrolling pour >200 messages. Si la performance se dégrade :
- Le cap client est fixé à 1000 messages en mémoire (les plus anciens sont purgés côté client)
- Si le nombre total dépasse 5000 en base, les plus anciens sont purgés côté serveur
- Utiliser "Clear exchanges" pour repartir d'un état vide
### 5.4 L'inspecteur XML affiche du contenu brut (non formaté)
Si le XML n'est pas mis en forme :
- Le XML est peut-être malformé → l'inspecteur affiche le contenu brut en fallback
- Vérifier si le message a un `rawXml` vide (cas "Empty")
---
## 6. Feature flags et rollback
### 6.1 Flags disponibles
| Variable d'environnement | Défaut | Effet si `false`/`file` |
|--------------------------|--------|-------------------------|
| `FEATURE_EXCHANGE_PERSISTENCE` | `true` | Les échanges ne sont pas écrits en MongoDB |
| `FEATURE_SSE_ENABLED` | `true` | L'endpoint SSE retourne 503, le client utilise le REST polling (5s) |
| `FEATURE_EXCHANGE_API_SOURCE` | `mongodb` | Si `file`, l'API lit depuis l'ancien système de fichiers |
### 6.2 Procédure de rollback rapide
En cas de problème critique :
```bash
# 1. Désactiver la persistance (les sessions CWMP continuent normalement)
FEATURE_EXCHANGE_PERSISTENCE=false
# 2. Désactiver le SSE (le frontend utilise le polling REST)
FEATURE_SSE_ENABLED=false
# 3. Revenir à la source fichier pour l'API
FEATURE_EXCHANGE_API_SOURCE=file
```
Redémarrer l'application après modification :
```bash
docker compose restart app
```
### 6.3 Vérifier l'état actuel des flags
Les valeurs actives sont loguées au démarrage de l'application. Vous pouvez aussi interroger le health check :
```bash
curl -s http://localhost:8080/api/v1/health/tr069-exchanges | python3 -m json.tool
```
---
## Commandes utiles — Résumé rapide
```bash
# Status général
docker compose logs app --tail 20 | grep -E '\[ExchangeStore\]|\[SSE\]'
# Compter les échanges d'un device
docker compose exec mongodb mongosh --eval "use adam_acs; db.cwmp_exchanges.countDocuments({deviceId:'<ID>'})"
# Vérifier les index
docker compose exec mongodb mongosh --eval "use adam_acs; db.cwmp_exchanges.getIndexes().forEach(i=>printjson(i))"
# Vérifier le TTL monitor
docker compose exec mongodb mongosh --eval "printjson(db.adminCommand({serverStatus:1}).metrics.ttl)"
# Tester la connexion SSE manuellement
curl -N -H "Accept: text/event-stream" http://localhost:8080/api/v1/tr069-trace/<DEVICE_ID>/exchanges/stream
# Tester la reconnexion avec Last-Event-ID
curl -N -H "Accept: text/event-stream" -H "Last-Event-ID: 42" http://localhost:8080/api/v1/tr069-trace/<DEVICE_ID>/exchanges/stream
# Purger les échanges d'un device
curl -X DELETE http://localhost:8080/api/v1/tr069-trace/<DEVICE_ID>/exchanges
