Monitoring Checklist: Before You launch

📅 March 19, 2026 ⏱️ 8 min read

You've built the thing. Now make sure it doesn't fall over when real users show up.

Here's a practical monitoring checklist to run through before launching any production application. It's not comprehensive monitoring — it's the minimum viable setup that catches the most common failure modes.

Why This Matters

Post-launch monitoring serves three purposes:

Early detection: Know about problems before users report them
Incident response: Have data to debug when things break
Trust building: Public status pages show you take reliability seriously

                The goal: Set up monitoring in < 30 minutes that catches 80% of common failure modes. You can always add sophistication later.
            

The Pre-Launch Monitoring Checklist

Core Health Checks

Application responds to HTTP requests (basic uptime check)
Database accepts connections (query health)
SSL certificate is valid and not expiring soon
DNS resolves correctly from multiple locations

Key Functionality

User signup/login flow works end-to-end
Core user actions complete successfully (create, read, update, delete)
Payment flow works (if applicable)
Email delivery works (transactional emails)

Background Jobs

Scheduled tasks are running (cron jobs, queues)
Failed jobs alert someone (email, Slack)
Job queue isn't backed up

External Dependencies

Third-party APIs respond (payment, email, storage)
CDN serves assets correctly (if applicable)
External authentication works (OAuth providers)

Alerting Setup

Alerts go to the right person/team
Alert thresholds are reasonable (not too sensitive)
On-call rotation is defined (if applicable)
Escalation path is clear

What You DON'T Need Yet

Complex dashboards (you won't look at them)
Multi-region monitoring (single region is fine to start)
Synthetic transactions (real user traffic is more valuable)
ML-based anomaly detection (traditional thresholds work fine)

                Rule of thumb: If you're spending more time setting up monitoring than building the initial feature, you're over-engineering.
            

How to Set This up quickly

Step 1: Basic Uptime Monitoring (10 minutes)

Use a service like OpsPulse, UptimeRobot, or Pingdom to check your main endpoints:

Landing page
API health endpoint
Key user flow (signup, login)

Step 2: SSL Monitoring (2 minutes)

Most monitoring services include SSL expiry checks. Enable them. Set alerts for 14 days before expiry.

Step 3: Cron Job Monitoring (5 minutes)

For each scheduled job:

Add a heartbeat check (job pings your monitoring service when complete)
Set up failure alerts (if job doesn't complete within expected time)

Step 4: Basic Alerting (10 minutes)

Configure notification channel (email, Slack, Telegram)
Set reasonable thresholds (consecutive failures, not single blips)
Test the alert flow (trigger a test alert)

Step 5: Status Page (optional, 5 minutes)

If you have users, create a simple status page. Many monitoring services include this feature. Enable it.

Testing Your Setup

Before launching, verify your monitoring works:

Temporarily break something (disable an endpoint) and confirm you get an alert
Check that alerts go to the right person
Verify your status page reflects the outage
Confirm resolution (fix the endpoint, verify alert clears)

Post-Launch Priorities

After launch, add monitoring based on actual incidents:

Database connection pool exhaustion
Memory leaks
Slow queries
Third-party API rate limiting

                Principle: Monitor what breaks, not what might break. Start with real incidents, then add proactive monitoring.
            

The Bottom Line

Monitoring doesn't prevent failures — it helps you respond faster. The goal is to know about problems before users do, and have data to fix them quickly when they happen.

Spend 30 minutes before launch. It's the best investment you'll make in reliability.
