Content Structure & Design

Document 1: Observability Architecture (08-observability.md)

Type: Architecture / Reference Guide
Template: Custom (architectural reference)

Front Matter:

---
title: 'Observability & Monitoring'
description: 'Health checks, structured logging, and failure modes for portfolio app'
sidebar_position: 8
tags: [observability, monitoring, health-checks, logging, architecture]
---

Content Outline:

Section 1: Overview

Purpose: Explain what observability is and why it matters for portfolio app

  • What is observability? (vs. monitoring, logging, alerting)
  • Why it matters: faster incident response, reduced MTTR
  • Observability pillars: logs, metrics, traces (current stage: logs + health check)
  • Architecture diagram (3-tier: app → health checks → Vercel logs → external systems)

Section 2: Health Check Endpoint

Purpose: Document the /api/health endpoint capabilities

  • Endpoint URL: GET /api/health
  • Response format: JSON with status, timestamp, environment, commit, buildTime, projectCount
  • Status codes: 200 (healthy), 503 (degraded), 500 (unhealthy)
  • Testing: curl http://portfolio.example.com/api/health
  • Response examples:
    • Healthy response (200)
    • Degraded response (503)
    • Unhealthy response (500)

Section 3: Structured Logging

Purpose: Explain how structured logging works and how to use it

  • Log format: JSON with timestamp, level, message, context, environment
  • Log levels: info, warn, error, debug
  • Usage examples: 
    import { log } from '@/lib/observability';
log({ level: 'error', message: 'Failed to load project', context: { slug: 'abc' } });
  • Viewing logs: Where to find logs in Vercel console
  • Context guidelines: What to include in context, what not to expose

Section 4: Failure Modes Definition

Purpose: Define what each state means and how to detect it

  • Table: State → Definition → User Impact → HTTP Status → Recovery
    • Healthy: All routes work, analytics active, no errors → None → 200 → N/A
    • Degraded: Core routes work, some features unavailable → Minor → 503 → Monitor 5min
    • Unhealthy: Critical failures, routes return 500s → Major → 500 → Execute runbook

Section 5: Monitoring Integration

Purpose: Explain how monitoring systems integrate with observability

  • Health check monitoring: External monitors poll /api/health endpoint
  • Expected: 200 status within 5 seconds
  • Alert if: Status changes to 503/500, or endpoint unresponsive >30s
  • Structured logs: Sent to Vercel console, can be forwarded to external systems (Datadog, etc.)
  • Future integration: Metrics export (Prometheus, StatsD)

Section 6: Operational Readiness Checklist

Purpose: Provide checklist for operations team

  • Health endpoint deployed and accessible
  • Health endpoint returns 200 in production
  • Structured logging appears in Vercel console
  • Monitoring alerts configured for 503/500 status
  • Team trained on failure modes
  • Runbooks accessible and reviewed
  • On-call rotation aware of escalation procedures

Document 2: Service Degradation Runbook (rbk-portfolio-service-degradation.md)

Type: Runbook / Operational Procedure
Template: Operational Runbook

Front Matter:

---
title: 'Runbook: Portfolio App Service Degradation'
description: 'Detect, diagnose, and resolve service degradation scenarios'
sidebar_position: 2
tags: [runbook, operations, troubleshooting, degradation, incident-response]
---

Content Outline:

Section 1: Overview

  • Scenario: Application is slow, certain features unavailable, users report issues
  • Severity: Medium (users affected, but core functionality remains)
  • MTTR Target: 10 minutes (Time to restore)
  • On-call: Yes, notify on-call engineer

Section 2: Trigger Detection

How to detect degradation:

  • User reports in support channel (Slack, email)
  • Health endpoint returns 503 status
  • Vercel Logs show increased error rate
  • Analytics shows spike in API error responses
  • Response time monitoring shows >3s median response time

Section 3: Triage (1 minute)

Step-by-step:

  1. Confirm issue exists
    • Command: curl https://portfolio.example.com/api/health
    • Expected: Status 200; if 503 or 500, confirmed degraded/unhealthy
  2. Check environment
    • Command: curl https://portfolio.example.com/api/health | jq .
    • Verify environment (prod/staging), commit, build time
  3. Assess scope
  4. Initial judgment
    • Type A: Degraded (503) → Skip to Step 4 Contain
    • Type B: Unhealthy (500) → Skip to Step 5 Investigate
    • Type C: Slow (200 but slow) → Monitor for 2 min; if persists, investigate

Section 4: Containment (2 minutes)

Limit impact while investigating:

  1. Notify stakeholders
    • Post to #incidents: "Portfolio app experiencing degradation, investigating"
    • Assign incident number: INC-YYYYMMDD-001
  2. If recent deployment caused this:
    • Check Vercel Deployments page for recent deploy
    • If deployed <5 min ago, consider immediate rollback (Step 5)
  3. If environment variables recently changed:
    • Check Vercel project settings for recent changes
    • Revert if suspected

Section 5: Investigation (3–5 minutes)

Diagnose root cause:

  1. Check Vercel Logs
    • Go to Vercel dashboard → Portfolio App → Deployments → Logs
    • Look for recent errors or warnings
    • Filter by time (last 10 minutes)
  2. Analyze error patterns
    • Are errors consistent? Or intermittent?
    • Are they in application code or infrastructure?
    • Example error patterns:
      • Cannot load PROJECTS registry → data loading issue
      • NEXT_PUBLIC_* variable missing → env var issue
      • Timeout calling external API → network issue
  3. Identify root cause category:
    • Category A: Data Issue (projects registry empty/corrupted)
    • Category B: Configuration Issue (env vars missing/wrong)
    • Category C: Resource Issue (CPU/memory constrained)
    • Category D: External Dependency (slow/unavailable API)

Section 6: Recovery (2–5 minutes)

Execute fix based on root cause:

If Category A (Data Issue):

  1. Check if projects.ts file corrupted
    • Command: Verify file in GitHub: git show HEAD:src/data/projects.ts | head -20
    • If corrupted: Revert to last known good commit
    • Trigger redeploy

If Category B (Configuration Issue):

  1. Check env vars in Vercel settings
    • Go to Vercel dashboard → Settings → Environment Variables
    • Verify required vars are set: NEXT_PUBLIC_*, DATABASE_URL (if applicable)
    • If missing: Add/restore env var
    • Trigger redeploy

If Category C (Resource Issue):

  1. Verify not hitting concurrency limits
    • Check Vercel Logs for throttling indicators
    • If persistent, may need plan upgrade
    • Temporary fix: Clear browser cache, reduce concurrent requests

If Category D (External Dependency):

  1. Verify external APIs are responding
    • Test endpoint: curl https://external-api.example.com/health
    • If down: Create issue with external team, monitor for recovery
    • Temporary: Serve stale data if possible (fallback mechanism)

Section 7: Verification (1–2 minutes)

Confirm fix worked:

  • Health check returns 200: curl https://portfolio.example.com/api/health
  • Homepage loads (no 500s)
  • Projects page loads and displays projects
  • No errors in Vercel Logs (last 5 minutes)
  • Response times back to normal (<1s median)

Section 8: Post-Incident (async, within 24 hours)

Document incident for learning:

  1. Create incident postmortem document
    • Template: docs/_meta/templates/template-postmortem.md
    • Include: Trigger, root cause, timeline, resolution, preventive actions
  2. Implement preventive control
    • Example: Add automated env var validation in build step
    • Example: Add health check monitoring alert
    • Example: Add data validation in project registry loading
  3. Share learnings with team
    • Post postmortem summary in #incidents
    • Discuss what could have been prevented

Document 3: Deployment Failure Runbook (rbk-portfolio-deployment-failure.md)

Type: Runbook / Operational Procedure

Front Matter:

---
title: 'Runbook: Portfolio App Deployment Failure'
description: 'Detect deployment failures and execute rollback procedures'
sidebar_position: 1
tags: [runbook, operations, deployment, rollback, incident-response]
---

Content Outline:

Section 1: Overview

  • Scenario: New deployment failed or introduced breaking changes
  • Severity: High (service potentially broken or unavailable)
  • MTTR Target: 5 minutes (rollback execution)
  • On-call: Yes, notify immediately

Section 2: Failure Indicators

How to detect deployment failure:

  • Deployment status shows "Failed" in Vercel dashboard (red X)
  • Health endpoint returns 500 and accessible routes return 500
  • Build logs show compilation errors
  • Runtime errors appear immediately after deployment
  • Users report site completely broken

Section 3: Triage (1 minute)

Confirm deployment is failed:

  1. Check Vercel Deployments page
    • Go to Vercel dashboard → Portfolio App → Deployments
    • Identify failed deployment (red X icon)
    • Note: Deployment URL, commit SHA, timestamp
  2. Check if already live (rolled back?)
  3. Initial assessment
    • Did failure happen during build? (Build logs show error)
    • Did failure happen at runtime? (Deployment succeeds but errors at startup)

Section 4: Immediate Containment (1 minute)

Prevent further impact:

  1. Stop deploying
    • Tell team: No more deploys until this is resolved
    • Post to #deployments: "HOLD on deployments, investigating failure"
  2. Identify previous working deployment
    • Go to Deployments page, scroll down
    • Find most recent successful deployment (green checkmark)
    • Note: Commit SHA and deployment URL

Section 5: Execute Rollback (2–3 minutes)

Option 1: Vercel UI Rollback (Fastest)

  1. Go to Vercel Deployments page
  2. Find last known good deployment (green checkmark)
  3. Click on deployment
  4. Click "Promote to Production" button
  5. Confirm: "Yes, promote this deployment"
  6. Wait for promotion to complete (~30s)
  7. Verify: curl https://portfolio.example.com/api/health returns 200

Option 2: Git Rollback (if rollback button unavailable)

  1. Identify broken commit: git log --oneline | head -1
  2. Identify last known good: git log --oneline | head -3 | tail -1
  3. Create rollback commit: 
    git revert -m 1 <broken-commit-sha>
git push origin main
  4. Vercel automatically triggers new deployment
  5. Wait for deployment to complete and verify health check

Section 6: Verification (1–2 minutes)

Confirm rollback was successful:

  • Health check returns 200
  • Vercel Deployments shows latest deployment as "Ready" (green)
  • Homepage accessible and renders without 500s
  • Projects page loads and displays content
  • No new errors in logs (last 2 minutes)

Section 7: Post-Failure Investigation (async, within 2 hours)

Understand what went wrong:

  1. Examine build logs
    • Go to Vercel Deployments → Failed deployment → View Build Logs
    • Identify error messages
    • Search for: TypeScript errors, missing dependencies, config issues
  2. Examine broken commit
    • git show <broken-commit-sha> --stat (see what files changed)
    • Review changes: Could any have caused the failure?
  3. Root cause analysis:
    • Was it a code issue? (syntax error, missing import, logic error)
    • Was it a dependency issue? (missing or conflicting package)
    • Was it an environment issue? (missing env var, deployment config)
    • Was it a tooling issue? (build tool version, TypeScript config)

Section 8: Implement Fix & Redeploy (async)

Resolve the issue and redeploy:

  1. Fix the issue on a local branch
    • Example: Fix syntax error, add missing dependency, etc.
    • Test locally: pnpm build
  2. Commit and push
    • git commit -am "fix: resolve deployment failure"
    • git push origin fix/deployment-failure
  3. Create PR and get review
    • Create PR with description of issue and fix
    • Request review from team
    • Ensure CI passes before merge
  4. Merge and deploy
    • Merge PR to main
    • Vercel auto-deploys
    • Verify health check and functionality

Section 9: Postmortem (within 24 hours)

Document and prevent future failures:

  1. Create postmortem document
    • Root cause: What was the actual issue?
    • Why wasn't it caught? (What testing/process gap?)
    • What preventive controls are needed?
  2. Implement preventive actions
    • Example: Add pre-commit hook to check TypeScript
    • Example: Add stricter linting rules
    • Example: Add build test step before deployment
  3. Share learnings

Document 4: General Incident Response Runbook (rbk-portfolio-incident-response.md)

Type: Runbook / Framework

Front Matter:

---
title: 'Runbook: General Incident Response'
description: 'Framework for responding to any incident on portfolio platform'
sidebar_position: 3
tags: [runbook, operations, incident-response, framework, process]
---

Content Outline:

Section 1: Severity Levels

Define severity levels for quick classification:

Severity Definition Response Time Escalation
SEV-4 (Low) Non-user-impacting issue; cosmetic bugs, documentation errors <24 hours None
SEV-3 (Medium) Users minimally affected; slow page load, minor features unavailable <4 hours Team lead informed
SEV-2 (High) Significant user impact; features broken, data loss risk <1 hour On-call engineer paged
SEV-1 (Critical) Complete service outage; all users affected, revenue impact Immediate VP Engineering paged

Section 2: Incident Classification

Determine severity on page 1 of investigation:

  • Ask: Are users blocked from core functionality?
    • Yes → SEV-2 or SEV-1 (depending on scale)
    • No → SEV-3 or SEV-4 (depending on visibility)
  • Example classifications:
    • "Projects page shows 404" → SEV-2 (core feature broken)
    • "Contact form email not sending" → SEV-3 (non-core feature broken)
    • "Typo in homepage text" → SEV-4 (cosmetic)

Section 3: Incident Notification & Escalation

Who to notify based on severity:

Severity Notify Channel Urgency
SEV-4 Team lead Slack #portfolio-updates ASAP (within business hours)
SEV-3 On-call eng + Team lead Slack #incidents Within 15 minutes
SEV-2 On-call eng + VP Eng Slack #incidents + page on-call Immediately
SEV-1 Full team + VP Slack #incidents + SMS/phone call Immediately (everyone)

Section 4: Triage Phase (first 5 minutes)

Quick assessment:

  1. Verify the incident
    • Can you reproduce it? Yes/no?
    • Is it affecting multiple users or one? (check logs/metrics)
    • Is it affecting production? Staging? Both?
  2. Assess scope
    • How many users affected?
    • What functionality is broken?
    • What's the business impact?
  3. Classify severity
    • Use severity matrix above
    • Notify appropriate stakeholders
  4. Assign incident number
    • Format: INC-YYYYMMDD-NNN (e.g., INC-20260126-001)
  5. Open incident channel
    • Create Slack channel: #incident-INC-20260126-001
    • Post: Incident number, description, severity, initial assessment

Section 5: Investigation Phase (next 10–30 minutes)

Detailed diagnosis:

  1. Gather information
    • What changed recently? (Deployments, env vars, config)
    • When did it start? (Exact time helps identify deployments)
    • Is it reproducible? (Intermittent vs. persistent)
  2. Check monitoring
    • Vercel Logs: Any errors in last 30 minutes?
    • Metrics: Error rate spiked? Response time degraded?
    • Uptime checks: Any availability drops?
  3. Identify root cause
    • Follow runbooks for deployment failure, degradation, etc.
    • If not in runbook: Check recent changes (git log, env changes, infrastructure)
  4. Assign ownership
    • Who owns the affected component?
    • Who can implement the fix?

Section 6: Mitigation & Resolution Phase (5–60 minutes depending on severity)

Fix the issue:

  1. Temporary mitigation (if needed)
    • Can we serve degraded experience while fixing root cause?
    • Example: Show cached data instead of live data
    • Goal: Reduce user impact while investigating root cause
  2. Implement fix
    • Develop fix on fix branch
    • Test locally (pnpm build, pnpm test)
    • Get code review if possible (skip if SEV-1 and time-critical)
  3. Deploy fix
    • Merge to main
    • Vercel auto-deploys
    • Verify health check returns 200
  4. Monitor for regression
    • Watch logs for 10 minutes post-deployment
    • Monitor error rate, response time
    • Confirm no new issues introduced

Section 7: Communication

During incident:

  • Post updates every 5–10 minutes in #incident-* channel
  • Post format: [HH:MM] {status}: {update}
  • Example: [15:30] INVESTIGATING: Found error in project loading, checking database
  • Example: [15:35] MITIGATION: Deployed rollback, services recovering
  • Example: [15:40] RESOLVED: All systems operational, postmortem scheduled for tomorrow

After incident (all-clear):

  • Post in #incidents: "RESOLVED: INC-20260126-001 Portfolio app degradation"
  • Include: Duration, impact, root cause (brief)
  • Schedule postmortem: "Postmortem scheduled for [date] at [time]"

Section 8: Postmortem Phase (within 24 hours)

Learn and prevent:

  1. Schedule postmortem meeting
    • Invite: Responders, team lead, affected team members
    • Duration: 30–60 minutes depending on complexity
  2. Conduct postmortem
    • Timeline: What happened, when, how was it resolved
    • Root cause analysis: Why did this happen?
    • Contributing factors: What made it worse or prevented quick detection?
    • Preventive actions: How do we prevent this in future?
  3. Document postmortem
    • Use template: docs/_meta/templates/template-postmortem.md
    • Post to: Portfolio operations documentation
    • Share with: Full team
  4. Track preventive actions
    • Create GitHub issues for each preventive action
    • Assign owner
    • Set due date (within 1–2 sprints)

Section 9: Follow-Up

Implement learnings:

  1. Preventive controls
    • Example: Add automated alerting for error rate >5% in 1 minute
    • Example: Add pre-commit hook to prevent known issues
    • Example: Add test cases to prevent regression
  2. Process improvements
    • Example: Better runbook clarity
    • Example: Faster escalation procedures
    • Example: Additional monitoring coverage
