Incident Runbook Templates

Adaptable templates for incident response runbooks covering detection, triage, mitigation, resolution, and communication.

Do not use this skill when

• The task is unrelated to incident runbook templates
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.

Use this skill when

• Creating incident response procedures
• Building service-specific runbooks
• Establishing escalation paths
• Documenting recovery procedures
• Responding to active incidents
• Onboarding on-call engineers

Core Concepts

1. Incident Severity Levels

2. Runbook Structure

1. Overview & Impact
2. Detection & Alerts
3. Initial Triage
4. Mitigation Steps
5. Root Cause Investigation
6. Resolution Procedures
7. Verification & Rollback
8. Communication Templates
9. Escalation Matrix

Runbook prerequisites

Bind service, namespace, cluster context, database, owners, approved incident authority, evidence sources and rollback revision before adapting these templates. Thresholds, financial amounts, impact percentages and resolution messages are illustrative, never observed incident facts. Read-only triage comes first; mutations require an approved service-specific response. Verify actual smoke/rollback scripts in the target project before using them. No script is bundled or implied by this template.

Runbook Templates

Template 1: Service Outage Runbook

# [Service Name] Outage Runbook
 
## Overview
**Service**: Payment Processing Service
**Owner**: Platform Team
**Slack**: #payments-incidents
**PagerDuty**: payments-oncall
 
## Impact Assessment
- [ ] Which customers are affected?
- [ ] What percentage of traffic is impacted?
- [ ] Are there financial implications?
- [ ] What's the blast radius?
 
## Detection
### Alerts
- `payment_error_rate > 5%` (PagerDuty)
- `payment_latency_p99 > 2s` (Slack)
- `payment_success_rate < 95%` (PagerDuty)
 
### Dashboards
- [Payment Service Dashboard](https://grafana/d/payments)
- [Error Tracking](https://sentry.io/payments)
- [Dependency Status](https://status.stripe.com)
 
## Initial Triage (First 5 Minutes)
 
### 1. Assess Scope

Check service health

kubectl get pods -n payments -l app=payment-service

Check recent deployments

kubectl rollout history deployment/payment-service -n payments

Check error rates

curl -s "http://prometheus:9090/api/v1/query?query=sum(rate(http_requests_total{status=~'5..'}[5m]))"

 
### 2. Quick Health Checks
- [ ] Can you reach the service? `curl -I https://api.company.com/payments/health`
- [ ] Database connectivity? Check connection pool metrics
- [ ] External dependencies? Check Stripe, bank API status
- [ ] Recent changes? Check deploy history
 
### 3. Initial Classification
| Symptom | Likely Cause | Go To Section |
|---------|--------------|---------------|
| All requests failing | Service down | Section 4.1 |
| High latency | Database/dependency | Section 4.2 |
| Partial failures | Code bug | Section 4.3 |
| Spike in errors | Traffic surge | Section 4.4 |
 
## Mitigation Procedures
 
### 4.1 Service Completely Down

Step 1: Check pod status

kubectl get pods -n payments

Step 2: If pods are crash-looping, check logs

kubectl logs -n payments -l app=payment-service --tail=100

Step 3: Check recent deployments

kubectl rollout history deployment/payment-service -n payments

Step 4: ROLLBACK if recent deploy is suspect

kubectl rollout undo deployment/payment-service -n payments

Step 5: Scale up if resource constrained

kubectl scale deployment/payment-service -n payments --replicas=10

Step 6: Verify recovery

kubectl rollout status deployment/payment-service -n payments

 
### 4.2 High Latency

Step 1: Check database connections

kubectl exec -n payments deploy/payment-service -- \ curl localhost:8080/metrics | grep db_pool

Step 2: Check slow queries (if DB issue)

psql -h $DB_HOST -U $DB_USER -c " SELECT pid, now() - query_start AS duration, query FROM pg_stat_activity WHERE state = 'active' AND now() - query_start > interval '5 seconds' ORDER BY duration DESC;"

Step 3: Kill long-running queries if needed

No generic query termination: identify an exact authorized PID/database/owner,

reconfirm it is not our connection, then use the approved database runbook.

Step 4: Check external dependency latency

curl -w "@curl-format.txt" -o /dev/null -s https://api.stripe.com/v1/health

Step 5: Enable circuit breaker if dependency is slow

kubectl set env deployment/payment-service \ STRIPE_CIRCUIT_BREAKER_ENABLED=true -n payments

 
### 4.3 Partial Failures (Specific Errors)

Step 1: Identify error pattern

kubectl logs -n payments -l app=payment-service --tail=500 | \ grep -i error | sort | uniq -c | sort -rn | head -20

Step 2: Check error tracking

Go to Sentry: https://sentry.io/payments

Step 3: If specific endpoint, enable feature flag to disable

curl -X POST https://api.company.com/internal/feature-flags \ -d '{"flag": "DISABLE_PROBLEMATIC_FEATURE", "enabled": true}'

Step 4: If data issue, check recent data changes

psql -h $DB_HOST -c " SELECT * FROM audit_log WHERE table_name = 'payment_methods' AND created_at > now() - interval '1 hour';"

 
### 4.4 Traffic Surge

Step 1: Check current request rate

kubectl top pods -n payments

Step 2: Scale horizontally

kubectl scale deployment/payment-service -n payments --replicas=20

Step 3: Enable rate limiting

kubectl set env deployment/payment-service \ RATE_LIMIT_ENABLED=true \ RATE_LIMIT_RPS=1000 -n payments

Step 4: If attack, block suspicious IPs

kubectl apply -f - <<EOF apiVersion: networking.k8s.io/v1 kind: NetworkPolicy metadata: name: block-suspicious namespace: payments spec: podSelector: matchLabels: app: payment-service ingress:

• from:
• ipBlock:

cidr: 0.0.0.0/0 except:

• 192.168.1.0/24 # Suspicious range

EOF

 
## Verification Steps

Verify service is healthy

curl -s https://api.company.com/payments/health | jq

Verify error rate is back to normal

curl -s "http://prometheus:9090/api/v1/query?query=sum(rate(http_requests_total{status=~'5..'}[5m]))" | jq '.data.result[0].value[1]'

Verify latency is acceptable

curl -s "http://prometheus:9090/api/v1/query?query=histogram_quantile(0.99,sum(rate(http_request_duration_seconds_bucket[5m]))by(le))" | jq

Smoke test critical flows

./scripts/smoke-test-payments.sh

 
## Rollback Procedures

Rollback Kubernetes deployment

kubectl rollout undo deployment/payment-service -n payments

Rollback database migration (if applicable)

./scripts/db-rollback.sh $MIGRATION_VERSION

Rollback feature flag

curl -X POST https://api.company.com/internal/feature-flags \ -d '{"flag": "NEW_PAYMENT_FLOW", "enabled": false}'

Template 2: Database Incident Runbook

# Database Incident Runbook
 
## Quick Reference
| Issue | Command |
|-------|---------|
| Check connections | `SELECT count(*) FROM pg_stat_activity;` |
| Query recovery | Identify exact PID/database/owner and use the approved recovery runbook |
| Check replication lag | `SELECT extract(epoch from (now() - pg_last_xact_replay_timestamp()));` |
| Check locks | `SELECT * FROM pg_locks WHERE NOT granted;` |
 
## Connection Pool Exhaustion

-- Check current connections SELECT datname, usename, state, count() FROM pg_stat_activity GROUP BY datname, usename, state ORDER BY count() DESC;

-- Identify long-running connections SELECT pid, usename, datname, state, query_start, query FROM pg_stat_activity WHERE state != 'idle' ORDER BY query_start;

-- Inventory scoped idle connections; this query performs no termination. SELECT pid, datname, usename, state, state_change FROM pg_stat_activity WHERE datname = current_database() AND pid <> pg_backend_pid() AND state = 'idle' AND state_change < now() - interval '10 minutes'; -- Do not terminate connections in bulk. Reconfirm ownership, transaction impact -- and a specific approved recovery step with the database owner.

 
## Replication Lag

-- Check lag on replica SELECT CASE WHEN pg_last_wal_receive_lsn() = pg_last_wal_replay_lsn() THEN 0 ELSE extract(epoch from now() - pg_last_xact_replay_timestamp()) END AS lag_seconds;

-- If lag > 60s, consider: -- 1. Check network between primary/replica -- 2. Check replica disk I/O -- 3. Consider failover if unrecoverable

 
## Disk Space Critical

Check disk usage

df -h /var/lib/postgresql/data

Find large tables

psql -c "SELECT relname, pg_size_pretty(pg_total_relation_size(relid)) FROM pg_catalog.pg_statio_user_tables ORDER BY pg_total_relation_size(relid) DESC LIMIT 10;"

VACUUM to reclaim space

VACUUM FULL requires an exclusive lock and extra disk space;

never use it as a generic disk emergency remedy. Escalate to the DBA.

If emergency, delete old data or expand disk

Best Practices

Do's

• Keep runbooks updated - Review after every incident
• Test runbooks regularly - Game days, chaos engineering
• Include rollback steps - Always have an escape hatch
• Document assumptions - What must be true for steps to work
• Link to dashboards - Quick access during stress

Don'ts

• Don't assume knowledge - Write for 3 AM brain
• Don't skip verification - Confirm each step worked
• Don't forget communication - Keep stakeholders informed
• Don't work alone - Escalate early
• Don't skip postmortems - Learn from every incident
