easyMonitoring & Debugging

Lost Logs

The application is running, but logs are missing when trying to debug issues. Some containers show logs, others don't.

15 min

Initial Situation

A multi-container pod is deployed with a main application and a sidecar logger. The main application runs fine and you can see its logs with kubectl logs. However, the sidecar container writes logs to a file (/var/log/app.log) instead of stdout. When you try to check the sidecar logs with kubectl logs, nothing appears. This makes debugging issues with the logging system impossible.
