SRE On-Call Simulator
Step into the role of an SRE. Diagnose critical system outages using our simulated command-line interface. Run container inspect commands, analyze logs, and choose the correct mitigation plan to resolve the active outage.
How to diagnose outages?
When alerts fire, resist the urge to immediately restart systems. A structured diagnostic process starts with inspecting container states (`kubectl get pods`), checking error events (`kubectl describe pod`), and examining application exception outputs (`kubectl logs`). Diagnosing before acting prevents masking underlying software bugs.
Temporary vs. Permanent Fixes
Incident management focuses on two phases: Mitigation (the immediate action to stop the bleeding, like restarting pods to release connection pools) and Remediation (the permanent fix, like deploying a code hotfix to close connection leaks). Successful SRE teams apply both to guarantee high service reliability.
