## 2. PagerDuty Integration

### 2.1 Configuration

**Location**: `monitoring/alertmanager/alertmanager.yml`

**Integration Type**: Events API v2
**Endpoint**: `https://events.pagerduty.com/v2/enqueue`

**Routing Keys**:
- Ensemble Critical: `YOUR_PAGERDUTY_ENSEMBLE_INTEGRATION_KEY`
- General Critical: `YOUR_PAGERDUTY_SERVICE_KEY`

### 2.2 Alert Details Format

```yaml
pagerduty_configs:
  - routing_key: 'YOUR_PAGERDUTY_ENSEMBLE_INTEGRATION_KEY'
    severity: 'critical'
    description: '{{ .GroupLabels.alertname }}: {{ .CommonAnnotations.summary }}'
    details:
      alert_type: '{{ .CommonLabels.alert_type }}'
      symbol: '{{ .CommonLabels.symbol }}'
      impact: '{{ .CommonAnnotations.impact }}'
      action: '{{ .CommonAnnotations.action }}'
      runbook_url: '{{ .CommonAnnotations.runbook_url }}'
    client: 'Foxhunt Ensemble Monitoring'
    client_url: 'http://localhost:3000/d/ensemble-ml-production'
```

### 2.3 On-Call Rotation

**Recommended Schedule**:
- ML Engineer: Primary on-call (24/7)
- Risk Manager: Backup (business hours)
- DevOps: Escalation (24/7)
- CTO: Critical escalation (24/7)

**Escalation Policy**:
1. Alert fires → Page primary on-call
2. No ack after 5 minutes → Escalate to backup
3. No ack after 10 minutes → Escalate to DevOps + CTO
4. Critical cascade failure → Page all immediately

## 3. Slack Integration

### 3.1 Channels (3 channels)

| Channel | Purpose | Alerts | Severity |
|---------|---------|--------|----------|
| #foxhunt-ensemble-critical | Critical alerts requiring immediate action | 15 alerts | Critical |
| #foxhunt-ensemble-warnings | Warning alerts requiring investigation | 5 alerts | Warning |
| #foxhunt-ensemble-info | Informational alerts (A/B test results) | 2 alerts | Info |

### 3.2 Message Format

**Critical Alerts**:
```
🚨 ENSEMBLE CRITICAL: EnsembleSharpeRatioDropCritical

*Alert:* EnsembleSharpeRatioDropCritical
*Type:* performance
*Symbol:* ES.FUT

*Summary:* Ensemble Sharpe ratio dropped >50% in 15 minutes
*Description:* Current Sharpe ratio is 45.2% of baseline (threshold: 50%)
*Impact:* Strategy profitability severely degraded - potential regime shift or model drift

*Action Required:*
1. Check Grafana dashboard: http://localhost:3000/d/ensemble-ml-production
2. Review model disagreement rates
3. Check for market regime changes
4. Consider reducing position sizes or switching to defensive mode
5. Review model weights - any single model dominating?

*Runbook:* https://docs.foxhunt.io/runbooks/ensemble-sharpe-drop
```

**Warning Alerts**:
```
⚠️ ENSEMBLE WARNING: EnsembleHighDisagreementWarning

*Alert:* EnsembleHighDisagreementWarning
*Type:* disagreement
*Symbol:* NQ.FUT

*Summary:* Elevated model disagreement 50-70%
*Description:* Disagreement 55% on NQ.FUT (threshold: 50%)

**Info Alerts**:
```
ℹ️ ENSEMBLE INFO: EnsembleABTestSignificantLift

*Alert:* EnsembleABTestSignificantLift

*Summary:* A/B test showing significant Sharpe ratio lift
*Description:* Treatment group 25% better than control
```

### 3.3 Configuration Steps

```bash
# 1. Create Slack channels
# - #foxhunt-ensemble-critical
# - #foxhunt-ensemble-warnings
# - #foxhunt-ensemble-info

# 2. Create incoming webhooks for each channel
# Apps & Integrations → Incoming Webhooks → Add New Webhook

# 3. Update alertmanager.yml with webhook URLs
sed -i 's|YOUR/SLACK/WEBHOOK|T00000000/B00000000/XXXXXXXXXXXXXXXXXXXX|g' \
  monitoring/alertmanager/alertmanager.yml

# 4. Reload AlertManager
docker-compose restart alertmanager
```

---

## 4. Inhibition Rules (6 rules)

### 4.1 Purpose

Prevent alert storms by suppressing redundant alerts when a parent alert is firing.

### 4.2 Rules

1. **Cascade suppresses individual failures**
   - Source: `EnsembleCascadeFailureDetected`
   - Target: `EnsembleModelFailureDetected`
   - Reason: If 2+ models failed, individual failures are redundant

2. **Critical Sharpe drop suppresses warning**
   - Source: `EnsembleSharpeRatioDropCritical`
   - Target: `EnsembleSharpeRatioDropWarning`
   - Reason: Critical alert covers the warning case

3. **High memory suppresses latency alerts**
   - Source: `EnsembleServiceMemoryHigh`
   - Target: `EnsembleAggregationLatencyP99High`
   - Reason: Latency caused by memory pressure/swapping

4. **High rollback rate suppresses individual failures**
   - Source: `EnsembleCheckpointRollbackRateHigh`
   - Target: `EnsembleCheckpointSwapFailed`
   - Reason: Systematic rollback issue covers individual failures

5. **Critical disagreement suppresses warning**
   - Source: `EnsembleHighDisagreementCritical`
   - Target: `EnsembleHighDisagreementWarning`
   - Reason: Critical alert covers the warning case

6. **Low confidence + high disagreement suppresses individual alerts**
   - Source: `EnsembleLowConfidenceHighDisagreement`
   - Target: `EnsembleHighDisagreementCritical|EnsembleHighDisagreementWarning`
   - Reason: Combined alert is more severe than individual ones

## 7. Key PromQL Queries

### 7.1 Performance Monitoring

**Sharpe Ratio Calculation**:
```promql
(
  sum(rate(ensemble_model_pnl_contribution_dollars_sum[15m])) /
  sqrt(sum(rate(ensemble_model_pnl_contribution_dollars_count[15m])))
)
```

**Win Rate**:
```promql
100 * (
  sum(rate(ensemble_predictions_total{action="buy"}[15m])) +
  sum(rate(ensemble_predictions_total{action="sell"}[15m]))
) /
sum(rate(ensemble_predictions_total[15m]))
```

**P&L Trend**:
```promql
sum(rate(ensemble_model_pnl_contribution_dollars_sum[30m]))
```

### 7.2 Disagreement Monitoring

**Disagreement Rate**:
```promql
ensemble_disagreement_rate
```

**Disagreement Spike Rate**:
```promql
rate(ensemble_high_disagreement_total{threshold="0.7"}[5m]) > 10
```

**Low Confidence + High Disagreement**:
```promql
(ensemble_confidence_score < 0.6) and (ensemble_disagreement_rate > 0.7)
```

### 7.3 Latency Monitoring

**P99 Aggregation Latency**:
```promql
histogram_quantile(0.99, rate(ensemble_aggregation_latency_microseconds_bucket[1m]))
```

**P95 Aggregation Latency**:
```promql
histogram_quantile(0.95, rate(ensemble_aggregation_latency_microseconds_bucket[2m]))
```

**Prediction Throughput**:
```promql
rate(ensemble_predictions_total[1m])
```

### 7.4 Model Health

**Model Prediction Count**:
```promql
sum(rate(ensemble_predictions_total[1m])) by (model_id)
```

**Checkpoint Rollback Rate**:
```promql
100 * (
  sum(rate(checkpoint_swaps_total{status="rollback"}[10m])) /
  sum(rate(checkpoint_swaps_total[10m]))
)
```

**Failed Models Count**:
```promql
count(
  sum(rate(ensemble_predictions_total[1m])) by (model_id) == 0
)
```

### 7.5 Weight Analysis

**Model Weight Distribution**:
```promql
ensemble_model_weight
```

**Weight Sum Validation**:
```promql
abs(sum(ensemble_model_weight) by (symbol) - 1.0)
```

**Dominant Model Detection**:
```promql
max(ensemble_model_weight) by (symbol) > 0.7
```

### 7.6 P&L Attribution

**Model P&L Ranking**:
```promql
topk(3, sum by (model_id) (ensemble_model_pnl_contribution_dollars_sum))
```

**Negative P&L Models**:
```promql
sum(rate(ensemble_model_pnl_contribution_dollars_sum[1h])) by (model_id, symbol) < -500
```
