Summary: UIMA-DUCC: refactor agent to fetch child process metrics
from cgroups
Key: UIMA-5245
URL: https://issues.apache.org/jira/browse/UIMA-5245
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.2.0-Ducc
Currently ducc gets swap, rss, major faults, and cpu usage for each child
process from variety of sources including ps, external scripts, cgroups. All
needed metrics are available in cgroups. The rss, swap and pgin can be fetched
from memory.stat file.
If cgroups are not ON, the values for the above metrics will be set to -1 and
shown as N/A to the user in the duccmon.
