[jira] [Created] (IMPALA-13164) Add metrics for RPC reactor and deserialization threads

Michael Smith created IMPALA-13164:
--------------------------------------

             Summary: Add metrics for RPC reactor and deserialization threads
                 Key: IMPALA-13164
                 URL: https://issues.apache.org/jira/browse/IMPALA-13164
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend, Distributed Exec
    Affects Versions: Impala 4.4.0
            Reporter: Michael Smith


When Impala starts to build up a queue in an RPC service, we generally need to start collecting pstacks to identify why the queue is backed up. It would help to have metrics for RPC reactor and deserialization threads to tell when they're fully loaded and building up a queue; this could identify when we need to increase {{datastream_service_num_deserialization_threads}} or {{num_reactor_threads}}.
