## ⚙️ How It Works

### 1. Grafana Startup

```
docker-compose up grafana
    │
    ├─► Loads datasources from provisioning/datasources/
    │   └─► OpenSearch (UID: grafana-opensearch-datasource)
    │
    ├─► Loads dashboards from provisioning/dashboards/
    │   └─► Evaluation Metrics Dashboard
    │
    └─► Loads alerting from provisioning/alerting/
        ├─► rules.yml (11 alert rules)
        ├─► contactpoints.yml (4 notification channels)
        └─► policies.yml (routing rules)
```

### 2. Alert Evaluation Cycle

```
Every N minutes (per rule interval):
1. Run OpenSearch query
2. Apply expression/reduce function
3. Check condition (>, <, ==, etc.)
4. If true for "for:" duration → FIRE
5. Route based on severity labels
6. Send to contact point(s)
7. Include dashboard/panel links
```

### 3. Notification Routing

```yaml
Alert Labels:
  severity: critical
  category: security
  detector: pii

↓ Matches Policy Rule:

routes:
  - receiver: security-team
    object_matchers:
      - ['severity', '=', 'critical']

↓ Sends to Contact Point:

contactPoints:
  - name: security-team
    type: email
    settings:
      addresses: "security@example.com"
```

## 🔧 Configuration Matrix

### Contact Points

| Name | Type | Default Recipient | Configurable |
|------|------|-------------------|--------------|
| default-email | Email | admin@example.com | ✅ Yes |
| security-team | Email | security@example.com | ✅ Yes |
| slack-alerts | Slack | Disabled (no webhook) | ✅ Yes |
| console-only | Console | Grafana logs | ❌ Fixed |

### Routing Policies

| Severity | Primary Contact | Secondary | Repeat Interval |
|----------|----------------|-----------|-----------------|
| Critical | security-team | slack-alerts | 1 hour |
| High | slack-alerts | - | 4 hours |
| Medium | default-email | - | 12 hours |
| Low | console-only | - | 24 hours |

### Query Data Sources

All alerts query OpenSearch:
- **Index Pattern**: `jaeger-span-*`
- **Time Field**: `startTimeMillis`
- **Datasource UID**: `grafana-opensearch-datasource`
- **Query Language**: Lucene (OpenSearch native)

## 📊 Dashboard Integration

### Alert → Dashboard Flow

When an alert fires:

1. **Notification includes**:
   ```
   Alert: Critical PII Exposure Detected

   Summary: High-confidence PII detected in LLM response

   Dashboard: http://grafana:3000/d/genai-evaluation-metrics
   Panel: Recent PII Detections

   Query Results: 3 detections in last 5 minutes
   ```

2. **User clicks dashboard link**:
   - Opens Evaluation Metrics Dashboard
   - Auto-scrolls to relevant panel
   - Highlights time range where alert fired

3. **User investigates**:
   - Views detection table
   - Clicks Trace ID
   - Opens Jaeger for full trace
   - Reviews context and takes action

### Dashboard Panels Used by Alerts

| Alert | Uses Panel | For |
|-------|-----------|-----|
| PII Exposure | Recent PII Detections | Trace IDs, scores |
| Toxicity Rate | Toxicity Over Time | Rate trending |
| Bias Rate | Bias Over Time | Rate trending |
| Prompt Injection | Prompt Injection Table | Attack patterns |
| Hallucination | Hallucination Table | Citation quality |

## 🎛️ Customization Points

### 1. Alert Thresholds

**File**: `provisioning/alerting/rules.yml`

```yaml
# Find this section:
conditions:
  - evaluator:
      params:
        - 0.7  # ← Change this threshold
      type: gt  # ← Or change comparison type
```

**Common adjustments**:
- PII score: 0.7 → 0.5 (more sensitive)
- Toxicity rate: 0.05 → 0.10 (less sensitive)
- Prompt injection count: 3 → 5 (less sensitive)

### 2. Alert Timing

```yaml
# Check interval
interval: 1m  # How often to evaluate

# Fire delay
for: 5m  # Must be true for this long

# Look-back window
relativeTimeRange:
  from: 300  # Seconds to look back
  to: 0
```

### 3. Notification Recipients

**File**: `provisioning/alerting/contactpoints.yml`

```yaml
contactPoints:
  - name: default-email
    receivers:
      - settings:
          addresses: "your-team@company.com"  # ← Change here
```

### 4. Routing Rules

**File**: `provisioning/alerting/policies.yml`

```yaml
routes:
  - receiver: security-team
    object_matchers:
      - ['severity', '=', 'critical']  # ← Add more matchers
      - ['detector', '=', 'pii']       # ← Like this
```

## 🧪 Testing

### Quick Test (Console Logging)

```bash
# 1. Start services
docker-compose up -d

# 2. Generate test data (run this in your app)
python -c "
from genai_otel import instrument
from genai_otel.evaluation import PIIConfig
instrument(enable_pii_detection=True, pii_config=PIIConfig(threshold=0.5))

import openai
client = openai.OpenAI()
for i in range(10):
    client.chat.completions.create(
        model='gpt-3.5-turbo',
        messages=[{'role': 'user', 'content': f'SSN: 123-45-{6789+i}'}]
    )
"

# 3. Wait 5 minutes

# 4. Check logs
docker-compose logs grafana | grep -i "firing\|resolved"
```

### Email Test

```bash
# 1. Configure SMTP in docker-compose.yml
# 2. Restart Grafana
docker-compose restart grafana

# 3. Test contact point
# Go to: Grafana UI → Alerting → Contact points → default-email → Test
```

## 📈 Monitoring the Monitors

### Check Alert Health

```bash
# View Grafana alerting logs
docker-compose logs grafana | grep -i alert

# Check evaluation errors
docker-compose logs grafana | grep -i "error.*alert"

# View notification history
# Grafana UI → Alerting → Contact points → [Contact] → View history
```

### Alert Metrics

Grafana exposes metrics about alerts themselves:

- `grafana_alerting_active_alerts` - Currently firing
- `grafana_alerting_rule_evaluations_total` - Evaluation count
- `grafana_alerting_rule_evaluation_failures_total` - Failed evaluations
- `grafana_alerting_notifications_sent_total` - Notifications sent

Access at: http://localhost:3000/metrics

## 🔐 Security Considerations

### 1. Credentials in Plain Text

**Issue**: SMTP passwords in docker-compose.yml

**Solutions**:
- Use Docker secrets
- Use environment file: `docker-compose --env-file .env.local up`
- Use Grafana provisioning secrets

### 2. Anonymous Access

**Current**: Anonymous admin enabled for demo

**Production**: Disable anonymous access:
```yaml
grafana:
  environment:
    - GF_AUTH_ANONYMOUS_ENABLED=false
    - GF_AUTH_ANONYMOUS_ORG_ROLE=Viewer
```

### 3. Alert Data Exposure

**Issue**: Notifications may contain sensitive data

**Mitigations**:
- Don't include query results in notifications
- Use secure channels (encrypted email, private Slack)
- Implement notification rate limiting

## 📝 Maintenance

### Regular Tasks

**Weekly**:
- Review firing alerts
- Check for alert fatigue (too many low-priority alerts)
- Verify contact points are working (test notifications)

**Monthly**:
- Review and adjust thresholds
- Update contact point recipients
- Clean up silences

**Quarterly**:
- Review all alert rules for relevance
- Update notification templates
- Performance test alert evaluation

### Updating Alerts

```bash
# 1. Edit rules
vi examples/demo/grafana/provisioning/alerting/rules.yml

# 2. Restart Grafana (picks up changes automatically)
docker-compose restart grafana

# 3. Verify in UI
# Grafana → Alerting → Alert rules → Check updated rules
```

## 🆘 Troubleshooting Guide

### Alert Not Firing

**Symptom**: Alert shows "Normal" but should be "Firing"

**Debug Steps**:
1. Check data exists: Run query in Explore
2. Check threshold: Verify condition in alert rule
3. Check "for:" duration: May need to wait longer
4. Check evaluation logs: `docker-compose logs grafana | grep "alert.*evaluation"`

### Notification Not Received

**Symptom**: Alert fires but no notification

**Debug Steps**:
1. Test contact point manually
2. Check notification history: Alerting → Contact points → History
3. Check SMTP logs: `docker-compose logs grafana | grep -i smtp`
4. Verify routing: Alerting → Notification policies

### Data Not Available

**Symptom**: Alert shows "No Data"

**Debug Steps**:
1. Check OpenSearch: `curl http://localhost:9200/jaeger-span-*/_count`
2. Check datasource: Configuration → Data sources → OpenSearch → Test
3. Check evaluation enabled: Verify app has evaluation features enabled
4. Check time range: Alert may be looking at wrong time window

## 🎓 Best Practices

### 1. Alert Naming

✅ **Good**: "Critical PII Exposure Detected"
❌ **Bad**: "PII Alert"

**Why**: Clear, specific, indicates severity

### 2. Alert Grouping

✅ **Good**: Group by `alertname` and `severity`
❌ **Bad**: Individual notification per alert

**Why**: Reduces noise, provides context

### 3. Repeat Intervals

✅ **Good**: Critical=1h, High=4h, Medium=12h, Low=24h
❌ **Bad**: All alerts repeat every 5 minutes

**Why**: Prevents alert fatigue

### 4. "For" Durations

✅ **Good**: Critical=1m, High=5m, Medium=15m
❌ **Bad**: All alerts fire immediately (for: 0s)

**Why**: Avoids false positives from transient issues

### 5. Actionable Alerts

✅ **Good**: "PII detected in responses. Review traces and audit data access."
❌ **Bad**: "Something wrong with PII."

**Why**: Clear next steps
