What logs and metrics are most useful for Databases on Kubernetes?

When managing databases on Kubernetes, it's essential to monitor various logs and metrics to ensure optimal performance and reliability. Key logs and metrics include:

  • Query Performance Logs: Capture slow queries and execution times to identify bottlenecks.
  • Connection Metrics: Monitor connection counts to manage resource utilization effectively.
  • Resource Usage Metrics: Track CPU and memory usage to ensure the database is running within its resource limits.
  • Error Logs: Capture database errors and warnings for quick troubleshooting.
  • Replication Status: Monitor replication lag and health in clustered environments.
  • Backup and Restore Logs: Ensure that backups are running successfully and can be restored as needed.
