Building a Production-Grade Uptime Monitoring Setup — What I Learned Running 100+ Checks

The 5 Mistakes Most Teams Make

1. Monitoring from a Single Location

A server in Virginia might show 200 OK while your users in London are getting timeout errors. Always monitor from multiple regions — ideally 3+ locations.

2. No SSL Certificate Monitoring

SSL certificates expire. When they do, your site goes down for everyone. Yet most monitoring setups only check HTTP status codes. SSL expiry alerts should be non-negotiable.

3. Email-Only Alerts

Email notifications at 3 AM will not wake you up. You need at least two channels — SMS or phone call for critical alerts, Slack/Discord for routine ones.

4. Checking the Wrong Metrics

Response time matters more than uptime percentage for user experience. A site returning 200 OK in 30 seconds is effectively down. Set thresholds for both status and performance.

5. No Status Page

Your users should not discover downtime from social media. A status page keeps them informed proactively and reduces support tickets during incidents.

What a Solid Monitoring Stack Looks Like

Core Checks (Every 1-5 minutes)

• HTTP(S) status: GET/HEAD requests to key endpoints
• SSL expiry: Warning at 30, 14, and 7 days
• Response time: P95 under 2 seconds
• Content validation: Check for specific text in responses

Alert Channels (Ranked by effectiveness)

1. Phone call — Guarantees you are awake
2. SMS — Works when apps do not
3. Slack/Discord — Good for team visibility
4. Email — Best for non-critical reports

Incident Response Flow

Alert fires → Auto-acknowledge → 5 min: First escalation →
10 min: Second escalation → 15 min: All-hands via phone
