Subject Re: UIMA AS get the component name from ProcessTrace
Date Tue, 11 Dec 2012 14:35:27 GMT
Florin, the newly released UIMA-AS 2.4.0 provides performance breakdown you
are looking for.
There is a new API on UIMA-AS client that facilitates this:

  public String sendAndReceiveCAS(CAS aCAS,
List<AnalysisEnginePerformanceMetrics> componentMetricsList) throws
ResourceProcessException;

For each CAS that you send you get a list of AEs with the performance
information.

If there is a failure in an AE, an exception is returned back to the client
which is thrown from the above API to the application.

The above API is for synchronous invocation only. We need to address how to
support per component performance breakdown in
async API. I had this coded at some point but it was backed out due to
backward compatibility problems.
