PBD directive question - internal classes

[David Richards]

Hi - one of our developers has asked me this and I dont' know the answer if anyone can help......

 

To monitor internal class do I identify using standard directive e.g.

 

IdentifyClassAs: org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker ……

 

 

Thanks for any help.

Any thoughts or pointers on this?

Hi,

 

IdentifyClassAs is for associating a specific class to the specified Tracer Group.

 

Format:

IdentifyClassAs:  <class> <Tracer Group>

 

You want to use one of the following.  The first one may open you up to a metrics explosion if you have a lot of methods in the class.

 

TraceAllMethodsOfClass

This traces all methods except for constructors () and static initializers () in the specified class. Class name should be fully qualified.

Format:

TraceAllMethodsOfClass:   <class> <Tracer> "<Investigator Tree Path>"

 

TraceOneMethodOfClass

This traces a specific method in the specified class. Class name should be fully qualified.

 

Format:

TraceOneMethodOfClass: <class> <method> <Tracer> "<Investigator Tree Path>"

 

Thanks,
Matt

Hi Dave:

Please let us know if Matt's answer was sufficient and we can mark this thread as Answered. Or if there are follow-up questions

Thanks

OK, thanks for the replies, but its not quite what I was looking for.

 

The specific class - org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker

 

has what they are referring to as an "internal" class - its after the dollar sign - AsyncMessageListenerInvoker

 

So the question is can we define the classname in that format - "org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker"

to work with "IdentifyClassAs" ?

 

After that we will use "TraceComplexMethods" as the Tracer.

 

Thanks

As long as its exposed to us you could write it as such:

 

IdentifyClassAs org.springframework.jms.listener.DefaultMessageListenerContainer$AsyncMessageListenerInvoker <name of tracer group>

 

and then

 

TraceComplexMethods: <name of tracer group> .....

[David Richards]

OK thanks, we will try that. Thanks again for the quick response.

Hi Dave:

  Please let us know soon if Matt's latest response solves the issue or follow-up assistance is required

Thanks

Hal

[David Richards]

Yes, will do. I have sent this response over to the developers so I will update this post once we have tested it.

Hi Dave:

   Since a response has been provided and there are no further action items, I have marked it as "Assumed Answered." I am not sure how long it is going to take to hear back from your developers. If it is going to take a while, we could mark it as Answered and you can unmark it later ,should it not work and you need further assistance.Let me know if that is acceptable.

 

Thanks
