[jira] [Created] (IMPALA-10912) Add offcputime analysis

Zoltán Borók-Nagy created IMPALA-10912:
------------------------------------------

             Summary: Add offcputime analysis
                 Key: IMPALA-10912
                 URL: https://issues.apache.org/jira/browse/IMPALA-10912
             Project: IMPALA
          Issue Type: Sub-task
            Reporter: Zoltán Borók-Nagy


offcputime analysis can be also useful for performance measurement.

It can be also visualized on a flame graph: https://www.brendangregg.com/FlameGraphs/offcpuflamegraphs.html

We probably want to add some filters to filter out threads that are just waiting for tasks.
