The error looked small. Logs were clean. Metrics were green. But the outage cost three hours.
Auditing SRE is about catching those silent failures before they bleed into incidents. It demands more than reading dashboards. It means measuring the health of the systems, the processes, and the people who maintain them.
An SRE audit starts with tracing how alerts are created, escalated, and resolved. Every alert should have a purpose, an owner, and a defined response path. Dead alerts—those that no one acts on—are dangerous. They breed false confidence.
The next layer is change management. Every migration, deployment, or config edit must leave an audit trail. Without logs that link change to consequence, troubleshooting collapses into guesswork.
Then comes runbook accuracy. Stale or incomplete runbooks fail under pressure. Auditing them means executing them exactly as written and fixing gaps on the spot. The best time to edit a runbook is while using it.
