⚡ Quick Setup (30 Minutes)

Step 1: Configure PagerDuty (10 minutes)

# 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)

# 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/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

# 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

# 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

# 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

# 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)

# Ack in PagerDuty immediately
# Post in Slack: "Investigating [ALERT NAME]"

2. Assess (2-5 minutes)

# 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)

# 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)

# Execute immediate response actions from runbook
# Example: Reduce position sizes, pause trading, restart service
# Document actions taken in incident log

5. Escalate (if needed)

# 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

# Verify alert has cleared
# Document resolution in incident log
# Post resolution summary in Slack
# Schedule post-mortem if needed
