[jira] Created: (UIMA-941) No ProcessTrace events for process calls
that take 0ms
No ProcessTrace events for process calls that take 0ms
------------------------------------------------------
Key: UIMA-941
URL: https://issues.apache.org/jira/browse/UIMA-941
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.2.2
Environment: Windows XP, Java 1.5
Reporter: Thilo Goetz
Priority: Minor
Found when testing release candidate 4 of 2.2.2. Here's the text of an email I wrote. Adam responded that it's probably a bug.
http://www.mail-archive.com/uima-dev%40incubator.apache.org/msg06565.html
I was just testing CVD for the next release, and tried
out the new performance report feature. Internally, this
uses the ProcessTrace feature of AnalysisEngine.process().
It seems that if the process() call returns very quickly,
i.e., in 0ms according to the Java timer, no ProcessTrace
sub-events are recorded. For example, I'm running the
tagger, and here's some output I get:
This one looks fine, as expected:
3/27/08 4:29:52 PM - 10: org.apache.uima.tools.cvd.MainFrame.internalRunAE(1570): INFO: Process trace of AE run:
Component Name: HmmTaggerTAE
Event Type: Analysis
Duration: 2078ms (100%)
Sub-events:
Component Name: WhitespaceTokenizer
Event Type: Analysis
Duration: 265ms (12.75%)
Component Name: Hidden Markov Model - Part of Speech Tagger
Event Type: Analysis
Duration: 1813ms (87.25%)
Component Name: Fixed Flow Controller
Event Type: Analysis
Duration: 0ms (0%)
Next one seems to have lost the tagger:
3/27/08 4:30:08 PM - 10: org.apache.uima.tools.cvd.MainFrame.internalRunAE(1570): INFO: Process trace of AE run:
Component Name: HmmTaggerTAE
Event Type: Analysis
Duration: 16ms (100%)
Sub-events:
Component Name: WhitespaceTokenizer
Event Type: Analysis
Duration: 16ms (100%)
Component Name: Fixed Flow Controller
Event Type: Analysis
Duration: 0ms (0%)
Finally, this one only has the flow controller:
3/27/08 4:30:19 PM - 10: org.apache.uima.tools.cvd.MainFrame.internalRunAE(1570): INFO: Process trace of AE run:
Component Name: HmmTaggerTAE
Event Type: Analysis
Duration: 0ms
Sub-events:
Component Name: Fixed Flow Controller
Event Type: Analysis
Duration: 0ms
Looking at this in the debugger, there are no subevents
there, so it's not a problem with the printing.
Is this expected, or is it a bug? Seems to me it is a bug,
but I'm not sure from the documentation.

[jira] Commented: (UIMA-941) No ProcessTrace events for process
calls that take 0ms
Posted by "Adam Lally (JIRA)" <ui...@incubator.apache.org>.
[ https://issues.apache.org/jira/browse/UIMA-941?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12749523#action_12749523 ]
Adam Lally commented on UIMA-941:
---------------------------------
In AnalysisEngineImplBase.buildProcessTraceFromMBeanStats, it is specifically checking for a time > 0 before adding an event. We could remove that check.
I think the intention of that check might have been for remote services where "analysis time" is not available (but "service call time" is), and so it was better to not log an analysis time than to log an artificial time of 0. A way to fix that would be to set times originally to -1 [indicating not applicable] and change them to 0 the first time any time is logged. A simpler alternative might be in the case where both service call time and analysis time are 0, to create an Analysis entry in the ProcessTrace, with a time of 0.
