## ⚡ Quick Setup (30 Minutes)

### Step 1: Configure PagerDuty (10 minutes)

```bash
# 1. Create integration in PagerDuty UI
# Services → [Service] → Integrations → Add Integration
# Integration Type: "Events API v2"

# 2. Copy routing key
PAGERDUTY_ROUTING_KEY="r1234567890abcdef1234567890abcdef"

# 3. Update alertmanager.yml
cd /home/jgrusewski/Work/foxhunt
sed -i "s|YOUR_PAGERDUTY_ENSEMBLE_INTEGRATION_KEY|${PAGERDUTY_ROUTING_KEY}|g" \
  monitoring/alertmanager/alertmanager.yml

# 4. Create general routing key for non-ensemble alerts
PAGERDUTY_GENERAL_KEY="r0987654321fedcba0987654321fedcba"
sed -i "s|YOUR_PAGERDUTY_SERVICE_KEY|${PAGERDUTY_GENERAL_KEY}|g" \
  monitoring/alertmanager/alertmanager.yml
```

### Step 2: Configure Slack (10 minutes)

```bash
# 1. Create 3 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 to Workspace

# 3. Copy webhook URLs and update config
SLACK_WEBHOOK="T00000000/B00000000/XXXXXXXXXXXXXXXXXXXX"
sed -i "s|YOUR/SLACK/WEBHOOK|${SLACK_WEBHOOK}|g" \
  monitoring/alertmanager/alertmanager.yml

# Note: Repeat for all 3 channels with separate webhooks
```

### Step 3: Deploy & Test (10 minutes)

# 1. Start Prometheus and AlertManager
docker-compose up -d prometheus alertmanager

# 2. Reload configurations
curl -X POST http://localhost:9090/-/reload

curl -X POST http://localhost:50052/admin/test_high_disagreement \
  -H 'Content-Type: application/json' \
  -d '{"symbol": "ES.FUT", "duration_seconds": 300}'

# 2. Model failure (fires immediately)
curl -X POST http://localhost:50052/admin/fail_model \
  -H 'Content-Type: application/json' \
  -d '{"model_id": "DQN"}'

# 3. Cascade failure (fires in 30 seconds)
curl -X POST http://localhost:50052/admin/fail_models \
  -H 'Content-Type: application/json' \
  -d '{"model_ids": ["DQN", "PPO", "MAMBA-2"]}'

# 4. Latency spike (fires in 1 minute)
curl -X POST http://localhost:50052/admin/inject_latency \
  -H 'Content-Type: application/json' \
  -d '{"latency_us": 75, "duration_seconds": 120}'

# 5. Sharpe ratio drop (fires in 15 minutes)
curl -X POST http://localhost:50052/admin/test_sharpe_drop \
  -H 'Content-Type: application/json' \
  -d '{"symbol": "ES.FUT", "drop_percentage": 60, "duration_seconds": 900}'
```

## 📋 On-Call Setup

### Recommended Rotation

| Role | Primary | Backup | Hours |
|------|---------|--------|-------|
| ML Engineer | @ml-oncall | @ml-team | 24/7 |
| Risk Manager | @risk-oncall | @risk-team | Business hours |
| DevOps | @devops-oncall | @devops-team | 24/7 |
| CTO | @cto | - | Critical escalation |

### Escalation Policy (PagerDuty)

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. Cascade failure → Page all immediately

## 🔍 Troubleshooting Common Issues

### Issue 1: Alerts not firing

```bash
# Check Prometheus is scraping Trading Service
curl http://localhost:9090/api/v1/targets | jq '.data.activeTargets[] | select(.job=="trading_service")'

# Verify ensemble metrics are being exported
curl http://localhost:9092/metrics | grep ensemble_

# Check alert rules are loaded
curl http://localhost:9090/api/v1/rules | jq '.data.groups[] | select(.name | contains("ensemble"))'
```

### Issue 2: PagerDuty not receiving alerts

```bash
# Test PagerDuty API manually
curl -X POST https://events.pagerduty.com/v2/enqueue \
  -H 'Content-Type: application/json' \
  -d '{
    "routing_key": "YOUR_ROUTING_KEY",
    "event_action": "trigger",
    "payload": {
      "summary": "Test Alert",
      "severity": "critical",
      "source": "manual-test"
    }
  }'

# Check AlertManager logs
docker-compose logs -f alertmanager | grep -i pagerduty
```

### Issue 3: Slack not receiving alerts

```bash
# Test Slack webhook manually
curl -X POST https://hooks.slack.com/services/YOUR/SLACK/WEBHOOK \
  -H 'Content-Type: application/json' \
  -d '{"text": "Test message"}'

# Check AlertManager logs
docker-compose logs -f alertmanager | grep -i slack
```

## 📊 Key Metrics to Monitor

### Dashboard Panels (Grafana)

1. **Active Alerts** - Real-time count of firing alerts
2. **Alert Firing Rate** - Alerts fired per hour (track trends)
3. **MTTR by Alert Type** - Mean time to resolution
4. **False Positive Rate** - Alerts resolved without action
5. **PagerDuty Incidents** - Incident count by severity
6. **Slack Message Volume** - Messages per channel

### Alert Health Metrics

```promql
# Total active alerts
count(ALERTS{alertstate="firing"})

# Critical alerts
count(ALERTS{alertstate="firing",severity="critical"})

# Alerts by component
count(ALERTS{alertstate="firing"}) by (component)

# Alert firing rate (per hour)
rate(ALERTS_total[1h])
```

## 🚨 Critical Alert Response Template

When a critical alert fires, follow this template:

**1. Acknowledge (0-2 minutes)**
```bash
# Ack in PagerDuty immediately
# Post in Slack: "Investigating [ALERT NAME]"
```

**2. Assess (2-5 minutes)**
```bash
# Open Grafana dashboard
open http://localhost:3000/d/ensemble-ml-production

# Check alert details in Prometheus
open http://localhost:9090/alerts

# Review runbook
open docs/monitoring/ENSEMBLE_ALERT_RUNBOOKS.md
```

**3. Investigate (5-15 minutes)**
```bash
# Follow runbook investigation steps
# Run PromQL queries
# Check service logs
journalctl -u trading_service -n 200 | grep -i "error\|failed"
```

**4. Respond (15-30 minutes)**
```bash
# Execute immediate response actions from runbook
# Example: Reduce position sizes, pause trading, restart service
# Document actions taken in incident log
```

**5. Escalate (if needed)**
```bash
# Escalate to backup on-call if:
# - Root cause not identified within 15 minutes
# - Issue requires specialized expertise
# - Multiple critical alerts firing

# Escalate to CTO if:
# - Cascade failure detected
# - Significant capital loss (>$10K)
# - Trading halted >1 hour
```

**6. Resolve**
```bash
# Verify alert has cleared
# Document resolution in incident log
# Post resolution summary in Slack
# Schedule post-mortem if needed
```
