---------------------------------
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.
