Subject Debugging, logging and measuring operator subtask performance
Date Wed, 25 Jan 2017 18:51:31 GMT

As I am experiencing certain performance degradations in a streaming job, I want to determine
the root cause of it by measuring subtask performance in terms of resource utilisation - e.g.
CPU utilisation of the thread. 

Is this somehow possible? Does Flink log scheduled and executed threads? What approach would
you recommend? 

Thanks in advance,
