|-------|----------|---------|-------------|
| `HighFallbackModeUsage` | Warning | >50% fallback 5min | Model unavailable |
| `EmbeddingServiceDown` | Critical | No real embeddings 5min | Service down |

**Examples**:
```yaml
# Using fallback mode too much
sum(rate(embedding_generated_total{mode="fallback"}[5m]))
/ sum(rate(embedding_generated_total[5m])) > 0.5

# No real embeddings being generated
sum(rate(embedding_generated_total{mode="real"}[5m])) == 0
```

### Analytics Alerts (2)

| Alert | Severity | Trigger | Description |
|-------|----------|---------|-------------|

| Alert | Severity | Trigger | Description |
|-------|----------|---------|-------------|
| `HighRejectionRate` | Warning | >10% rejection 5min | Many calls blocked |
| `KnowledgeGraphGrowthStalled` | Info | No growth 15min | Graph not updating |

**Examples**:
```yaml
# High rejection rate
sum(rate(circuit_rejected_calls[5m])) / sum(rate(circuit_total_calls[5m])) > 0.1

# Knowledge graph stopped growing
kg_entities_total offset 10m == kg_entities_total
```

### Verify Alerts

```bash
# Check Prometheus rules
curl http://localhost:9090/api/v1/rules

# Check AlertManager status
curl http://localhost:9093/api/v1/status

# View active alerts
