## 🔄 **How It Works**
|
|
|
|
### Configuration-Based Switching
|
|
|
|
**Use RAG:**
|
|
```bash
|
|
export INTENT_DETECTION_CLIENT=rag
|
|
export RAG_SERVER_URL=https://your-rag-server.com
|
|
export RAG_SERVER_API_KEY=your-api-key
|
|
```
|
|
|
|
**Use Dialogflow:**
|
|
```bash
|
|
export INTENT_DETECTION_CLIENT=dialogflow
|
|
```
|
|
|
|
### Request Flow
|
|

|
## 🔍 **Monitoring**
|
|
|
|
### Key Metrics
|
|
|
|
| Metric | Target | How to Monitor |
|
|
|--------|--------|----------------|
|
|
| Response Time (p95) | < 2s | Log entries: "RAG query successful" |
|
|
| Error Rate | < 0.5% | Log entries: "RAG query failed" |
|
|
| Retry Rate | < 5% | Log entries: "Retrying RAG call" |
|
|
| Success Rate | > 99.5% | Count successful vs failed requests |
|
|
|
|
### Log Patterns
|
|
|
|
**Success:**
|
|
```
|
|
INFO Initiating RAG query for session: <session-id>
|
|
INFO RAG query successful for session: <session-id>
|
|
```
|
|
|
|
**Failure:**
|
|
```
|
|
ERROR RAG server error for session <session-id>: status=500
|
|
ERROR RAG retries exhausted for session <session-id>
|
|
```
|
|
|
|

|
|
|
|
## 🛡️ **Rollback Plan**
|
|
|
|
If issues occur:
|
|
|
|
### Step 1: Switch Configuration (< 1 minute)
|
|
```bash
|
|
export INTENT_DETECTION_CLIENT=dialogflow
|
|
```
|
|
|
|
### Step 2: Restart Application
|
|
```bash
|
|
kubectl rollout restart deployment/capa-integracion
|
|
```
|
|
|
|
### Step 3: Verify
|
|
```
|
|
✓ Intent detection configured to use Dialogflow CX client
|
|
```
|
|
|
|
**No code changes needed. No data loss.**
