Question

What are common best practices for collecting logs for the problem investigation of a support ticket?

Answer

Separate the logs based on process/pod roles into separate files (e.g. JM, TM, etc.).
Collect plain Flink or Ververica Platform logs, order by time. Avoid JSON/CSV format if possible.
- JSON/CSV formats often contain redundant info timestamps or container metadata.
Collect logs only for the relevant time frame, share additional logs when requested.
Collect logs only for the relevant job/deployment.
Compress large logs files before attaching.
