What Happened

Excessive log output from applications filled up the disk, slowing down the entire cluster.

Diagnosis Steps

1Monitored disk usage and found that logs were consuming most of the disk space.
2Identified the affected applications by reviewing the logging configuration.

Root Cause

Applications were logging excessively, and log rotation was not properly configured.

Fix/Workaround

• Configured log rotation for the affected applications.
• Reduced the verbosity of the logs in application settings.

Lessons Learned

Proper log management and rotation are essential to avoid filling up disk space and impacting cluster performance.
