[jira] [Created] (UIMA-4637) DUCC Agent should test if CPU control is enabled on startup

Jerry Cwiklik created UIMA-4637:
-----------------------------------

             Summary: DUCC Agent should test if CPU control is enabled on startup
                 Key: UIMA-4637
                 URL: https://issues.apache.org/jira/browse/UIMA-4637
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.1.0-Ducc


Extend agent cgroup sanity check to include a test for existence of CPU control. Users my forget to add cpu in their cgconfig.conf and start cgroups with no CPU control. The agent should call cgset and disable cgroups on failure. 
Agent should keep the state of cgroup in memory and log it at some interval to make sure this info is not lost. Currently the agent logs the state of cgroups (enabled/disabled) at startup only. When agent logs roll over this is lost. Modify agent node metrics logic to dump the cgroup state at regular intervals.
