Subject [jira] [Created] (FLINK-3263) Log task statistics on TaskManager
Date Tue, 19 Jan 2016 20:58:39 GMT
Greg Hogan created FLINK-3263:

             Summary: Log task statistics on TaskManager
                 Key: FLINK-3263
                 URL: https://issues.apache.org/jira/browse/FLINK-3263
             Project: Flink
          Issue Type: Improvement
          Components: TaskManager
    Affects Versions: 1.0.0
            Reporter: Greg Hogan
            Assignee: Greg Hogan
            Priority: Minor

Similar to how memory statistics can be written to the TaskMangers' log files by configuring
{{taskmanager.debug.memory.startLogThread}} and {{taskmanager.debug.memory.logIntervalMs}},
it would be useful to have statistics written for each task within a job.

One use case is to reconstruct progress to analyze why TaskManagers take different amounts
of time to process the same quantity of data.

I envision this being the same statistics which are displayed on the web frontend.
