Custom PBD to instrument a Class

[Anon Anon]

Hi All,

 

Im trying to check the performance of a class with the following custom PBD, but its not working for me, dont see any errors but the metrics are also not showing up the Investigator.

These are FUSE services. The class is MyClass

 

 

####################################################################################

 

#Custom  PBD

 

####################################################################################

SetFlag: Custom

TurnOn: Custom

IdentifyInheritedAs: com.company.impl.MyClass Custom

IdentifyClassAs: com.company.impl.MyClass Custom

TraceAllMethodsOfClass: com.company.impl.MyClass BlamePointTracer "CustomPBD|Apps|New1"

Please correct me if Im writing anything wrong and suggest me the right one.

 

Thanks

Harsh

Hi Harsha,

You/we would need to look at the AutoProbe log for the server to see if the class you want to monitor is actually being loaded and also if your pbd has been loaded as well.

 

Looking at the pbd, I think there is some confusion with the syntax because you have defined a tracer group but you didn't really tell the tracer to use it.

What's confusing then is that technically the last line could be enough by itself to generate metrics (TraceAllMethodsOfClass: com.company.impl.MyClass BlamePointTracer "CustomPBD|Apps|New1")

 

The last line should include a reference to your tracer group flag, then you have a syntax of TraceAllMethodsIfFlagged: <tracer group> <tracer name> <metric name>

 

TraceAllMethodsIfFlagged: Custom BlamePointTracer "CustomPBD|Apps|New1"

 

So it would then look like this

 

SetFlag: Custom

TurnOn: Custom

IdentifyInheritedAs: com.company.impl.MyClass Custom

IdentifyClassAs: com.company.impl.MyClass Custom

TraceAllMethodsIfFlagged: Custom BlamePointTracer "CustomPBD|Apps|New1"

 

If that doesn't help, we need to see the AutoProbe log.

 

Thanks,

David
