Measure a recursive method

[CommunityUser]

Hi,

I'd like to measure a recursive Java-method and split every call by the first parameter.

Is there any way my AppDynamics Pro-version can do this?

Thanks in advance for your answer.

Hi ,

Have you gone through the follwoing feature, pojo BT split option:

https://docs.appdynamics.com/display/PRO41/POJO+Entry+Points#POJOEntryPoints-pojo-splittingDynamical...

Thanks for the reply.

I created a new POJO-type entry point rule, checked "Match Classes with a Class Name that Equals *full class name*" and "Method Name Equals *call*".
On the Transaction-Splitting tab I selected the first two checkboxes and entered "Parameter index *0* Getter Chain to run on method parameter *toString()*".
..saved the rule, restarted the IBM-Websphere server, triggered the Application and waited for my Transaction-Snapshots to pop up.

As soon as a snapshot was displayed I clicked on it and chose "View Transaction Snapshot".

Then I "drilled down" where I opened the call graph. (I attached an example call graph)

Now what I'd like to see is with which parameter every recursive call of the call-Method was invoked with.

Hi,

Can you check if below feature helps , add collector on target method parameter index this will be part of snapshot/call graph for new load in UI:

Hi,

the technical issues were resolved and I could finally test the Data Collector.

Unfortunately, I have still not reached my desired goal.

The Data Collector shows all the first parameters of the called recursive function but in a different window ("User Data").

What I need is a combined view of those parameters within the callgraph.

Is there something else I can try?

Sincere regards,

Hi Ramiz,

 See if adding "snapshot data" config as part of CEP rule helps here,Custom exit point will be shows like JDBC/HTTP backend in call graph exit calls column and in the popup you should see snapshot data config added on target API:

Hi Akumar,

thank you very much for your patience and help!

Today I tested the Custom Exit Points and now I finally get the needed information in the snapshots call graph.

Best regards,

Hi,

thanks for the quick reply!

Unfortunately, we have some technical difficulties with our server at the moment and I can't access our AppDynamics-Controller.

I will test the Data Collector and reply as soon as possible.

Sincere regards,

Ramiz
