What is Support?
Support is the operational work that keeps production systems running smoothly. This includes monitoring, debugging, incident response, and optimization.
Support maintains Solutions, troubleshoots Systems, debugs Software, and monitors Services.
Runbook: Database Queries Suddenly Slow
Symptom
API responses taking 5-30 seconds. Users reporting "loading forever" on dashboard. Vercel Analytics showing increased database timeout errors.
Severity: High
Users can't access critical features
Time to Fix: 30-60 minutes
Diagnosis + index creation
Diagnosis Steps
- Check Supabase Dashboard
# Navigate to Supabase Dashboard https://supabase.com/dashboard/project/YOUR_PROJECT/logs # Filter for slow queries (>1s execution time) Filter: "duration > 1000"
- Identify slow query pattern
# Common culprits: - SELECT * FROM large_table WHERE unindexed_column = 'value' - JOINs without proper indexes - ORDER BY on unindexed columns
- Run EXPLAIN ANALYZE
-- In Supabase SQL Editor EXPLAIN ANALYZE SELECT * FROM users WHERE email = 'test@example.com'; -- Look for: -- "Seq Scan" = BAD (no index used) -- "Index Scan" = GOOD (index used)
- Check index usage
-- See which indexes exist and are being used SELECT schemaname, tablename, indexname, idx_scan as times_used FROM pg_stat_user_indexes WHERE schemaname = 'public' ORDER BY idx_scan ASC; -- idx_scan = 0 means index never used (consider dropping)
Fix Steps
- Create missing index
-- Example: Email lookup slow CREATE INDEX CONCURRENTLY idx_users_email ON users(email); -- CONCURRENTLY = no table lock during creation -- Safe for production with active traffic
- Verify index creation
-- Check index exists SELECT indexname, indexdef FROM pg_indexes WHERE tablename = 'users' AND indexname = 'idx_users_email';
- Re-run slow query
EXPLAIN ANALYZE SELECT * FROM users WHERE email = 'test@example.com'; -- Should now show: -- "Index Scan using idx_users_email" -- Execution time: <10ms (was 5000ms+)
- Monitor production impact
# Vercel Analytics (if using) - Check p95 response time improvement # Vercel Analytics - Verify database timeout errors decreased # Supabase Dashboard - Confirm slow query count dropped
Prevention
- Index planning: Add indexes for all WHERE, JOIN, and ORDER BY columns
- Query testing: Run EXPLAIN ANALYZE on all queries before production
- Monitoring: Set up Supabase alerts for queries >1s execution time
- Regular audits: Review pg_stat_user_indexes monthly, drop unused indexes
- Load testing: Test with production-scale data before deploy
Common Production Issues (Quick Reference)
Authentication Loops
Symptom: Users stuck redirecting between /login and /dashboard
Fix: Check middleware matcher excludes /login route
Code: export const config = { matcher: ['/dashboard/:path*'] }
Build Failures on Vercel
Symptom: "Type error: Cannot find module" during build
Fix: Run npm run build locally first, fix TypeScript errors
Prevention: Add npm run type-check to pre-commit hooks
API Rate Limit Exceeded
Symptom: 429 errors from Claude API, users can't get AI responses
Fix: Implement client-side rate limiting with Upstash Redis
Code: @upstash/ratelimit with sliding window
Environment Variables Not Loading
Symptom: process.env.SUPABASE_URL is undefined in production
Fix: Add to Vercel dashboard → Settings → Environment Variables
Gotcha: Redeploy after adding env vars (not automatic)
Essential Monitoring Setup
| Tool | What to Monitor | Alert Threshold | Cost |
|---|---|---|---|
| Vercel Analytics |
| >10 errors/min | $0-26/mo |
| Vercel Analytics |
| p95 > 1s | $10-20/mo |
| Supabase Logs |
| >10 slow queries/min | Included in Pro ($25/mo) |
| Uptime Robot |
| Any downtime | $0 (50 monitors) |

Incident Response Process
- Detect: Alert fires (Vercel Analytics, deployment logs, user reports)
- Assess Severity:
- Critical: Complete outage, data loss risk → Fix immediately
- High: Core features broken → Fix within 1 hour
- Medium: Degraded performance → Fix within 4 hours
- Low: Minor issues → Fix within 24 hours
- Communicate: Update status page, notify affected users if >5 min downtime
- Mitigate: Stop the bleeding (rollback, disable feature, scale resources)
- Diagnose: Use logs, metrics, and runbooks to find root cause
- Fix: Apply permanent solution, verify in production
- Document: Write post-mortem, update runbook, add monitoring
