Hi!

That is exactly the right way to do it. Logging has to be at least INFO and the parameter "taskmanager.debug.memory.startLogThread" set to true.

The log output should be under "org.apache.flink.runtime.taskmanager.TaskManager".

Do you see other outputs for that class in the log?

Make sure you restarted the TaskManager processes after you changed the config file.

Greetings,

Stephan

Hi,

I am trying to enable logging of memory usage on flink 0.10.0 by adding:

taskmanager.debug.memory.startLogThread: true

to config.yaml and setting log4j level to DEBUG however in the logs after running the job I cannot see any info regarding memory usage.My job lasted 30s so it should catch few intervals. Should I change something else in the configuration?

Best regards/Pozdrawiam,
