-----------------------------------
Summary: UIMA-DUCC: refactor agent code which gathers node and
process metrics
Key: UIMA-5047
URL: https://issues.apache.org/jira/browse/UIMA-5047
Project: UIMA
Issue Type: Improvement
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.2.0-Ducc
Currently agent fetches metrics from different sources including /proc file
system. The files found in /proc file system don't have fixed structure across
Linux platforms causing some metrics to be missing or be wrong.
Change the code to find an alternate way to get needed metrics from sources
that are more reliable.
Use cgroups cpu and memory accounting when cgroups are enabled. In case when
cgroups are not enabled provide 0 or N/A as values.
