Getting AE performance stats

[Jörn Kottmann]

Hello,

I am trying to retrieve performance stats from an AnalysisEngine
with the AnalysisEngineManagement object instance I got via the
AE.getManagementInterface method, but all stats are 0 e.g.
for AEM.getNumberOfCasProcessed().

I created the AE from a pear. And then this
small loop drives the processing:

CAS cas = ae.newCAS();
while (colReader.hasNext()) {
   colReader.getNext(cas);                      
   ae.process(cas);                                     
   cas.reset();
}

If I now try to use the management interface I do not
get correct stats, only zero as described above.

What do I am doing wrong ? Is there a switch
to explicitly enable performance monitoring ?

I have one more question.
Is it safe to use a second thread to retrieve the
performance stats ?

Thanks,
Jörn
