[jira] [Created] (SAMZA-2762) CPU metric(process-cpu-usage) doesn't count over child processes

Alan Zhang created SAMZA-2762:
---------------------------------

             Summary: CPU metric(process-cpu-usage) doesn't count over child processes
                 Key: SAMZA-2762
                 URL: https://issues.apache.org/jira/browse/SAMZA-2762
             Project: Samza
          Issue Type: Improvement
            Reporter: Alan Zhang


The "process-cpu-usage" metric only return the  “recent cpu usage” for the Java Virtual Machine process: [https://samza.apache.org/learn/documentation/1.6.0/operations/monitoring.html]

We have observed some use cases that created child processes(e.g. TensorFlow process to do model inference) outside the JVM. With current implementation, we can't know the CPU usage for these child processes.
