First Response Procedures

1. Database Service Outage 



# 1. Check service status

curl -f http://admin-panel/status || echo "Admin panel down"


# 2. Check PostHog for alerts


# Login: https://app.posthog.com/[YOUR_PROJECT_ID]


# Navigate: Dashboard → Database Performance


# Configure alerts for: query_time > 5s, connection_pool > 90%


# 3. Check database connectivity

psql -h db-host -U app_user -d penguinmails_oltp -c "SELECT 1;"


# 4. Check connection pools


# OLTP: Primary (5-50 connections)


# Content: Content (3-25 connections)


# Queue: Queue (5-40 connections)


# OLAP: Analytics (3-15 connections)


# 5. Execute failover if needed


# See: backup_recovery_procedures.md

2. Performance Degradation 

-- Check active queries
SELECT pid, usename, client_addr, state, query_start,
       EXTRACT(EPOCH FROM (now() - query_start)) as duration_seconds,
       left(query, 100) as query_preview
FROM pg_stat_activity
WHERE state = 'active'
ORDER BY query_start;

-- Check connection pool metrics
SELECT tier, pool_name, active_connections, idle_connections,
       connection_usage_rate, pending_acquires
FROM connection_pool_metrics cpm
JOIN connection_pool_config cpc ON cpm.pool_config_id = cpc.id
WHERE cpm.collected_at >= NOW() - INTERVAL '5 minutes'
ORDER BY cpm.collected_at DESC;
