Mean Time to Recovery (MTTR) explained

The Mean Time to Recovery (MTTR) is a DevOps metric that measures the average time taken to restore a service impacting users. It focuses on incident response rather than prevention. Poor MTTR can be caused by issues like poor problem discovery, lack of an incident management plan, and cumbersome deployment processes. To improve MTTR, teams should make code and error messages readable, put monitoring in place, review logs, have a process for managing incidents, and plan for failure. Automated deployments also contribute to quick recovery times. Monitoring system uptime/downtime, improving Deployment Frequency, and using feature flags can help improve MTTR metrics.
