[jira] [Created] (UIMA-3208) DUCCs Agent Computes Process CPU Usage Incorrectly

Jerry Cwiklik created UIMA-3208:
-----------------------------------

             Summary: DUCCs Agent Computes Process CPU Usage Incorrectly
                 Key: UIMA-3208
                 URL: https://issues.apache.org/jira/browse/UIMA-3208
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
    Affects Versions: 1.0-Ducc
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik


Modify agent to calculate the process usage as follows:

At the transition from init->run mode:
capture totalCpuUsage value and save as totalCpuInitUsage
capture current timestamp and save as clockAtStartOfRun

On each agent report for the process (or process group?) while in running state:
compute lastPercentCPU = 100 * (totalCpuUsage - totalCpuInitUsage) / (currentTimestamp - clockAtStartOfRun)

send lastPercentCPU

On each agent report after running state ends:
send lastPercentCPU (e.g. do not recompute)
