I Replaced My On-Call Runbook with AI — Here’s What Happened in Production

Last month I tried something risky. Instead of waking up at 3AM to debug production incidents, I experimented with an AI assistant handling the first layer of incident triage . No runbook. No manual log digging. Just AI analyzing alerts, logs, and metrics. Here’s what actually happened in production. The Problem Every On-Call Engineer Knows If you've ever been on call, you know the routine. PagerDuty fires. You open logs. You check dashboards. You run the same 5 commands. Every single time. The process is predictable, but it still requires a human in the loop. So I asked a simple question: Why can't AI do the first layer of incident investigation? The Idea Instead of engineers performing repetitive triage, I built a simple AI incident assistant . The AI receives alerts and performs initial debugging steps automatically. Architecture looked like this: Alert → AI Agent → Log Analysis → Root Cause Guess → Suggested Fix Tools used: OpenAI API GitHub Actions Kubernetes logs Prometheus metri
