-----------------------------------
Summary: UIMA-DUCC: instrument JP to log more details on negative performance
metrics
Key: UIMA-4896
URL: https://issues.apache.org/jira/browse/UIMA-4896
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.1.0-Ducc
Detect negative value for analysis time in UimaProcessContainer.doProcess() and log more details.
Performance breakdown for one job showed negative analysis time. This was only observed and
reported once. The hypothesis is that the JP provided bad data to the JD. Need proof that
this is indeed the case.
The JP code computes per CAS analysis time by doing before AE.process() and after snapshots
and than computing delta essentially:
after.analysisTime() - before.analysisTime. The uima-core analysisTime is cumulative and increasing
each time process is called. In theory the delta should always be > 0.
