splunk java agent

1234testtest — Mon, 28 Sep 2020 13:40:14 GMT

I have downloaded SplunkJavaAgent and set it to run in eclipse by giving arguments for javaagent during Tomcat startup and am getting events in Splunk through TCP but not what I want.

Following are the challenges I have.

**1. I would like to have method names, execution timings, call trace, application/thread stalls, errors/exceptions/throwables 2. Heap analysis*

I am not sure if I am doing right in splunkagent.properties - giving the details of the file.

agent.app.name=Tomcat
agent.app.instance=MyJVM
agent.userEventTags=key1=value1,key2=value2
splunk.transport.internalQueueSize=10000
splunk.transport.impl=com.splunk.javaagent.transport.SplunkTCPTransport
splunk.transport.tcp.host=localhost
splunk.transport.tcp.port=5150
splunk.transport.tcp.maxQueueSize=5MB
splunk.transport.tcp.dropEventsOnQueueFull=false
trace.whitelist=com/myinit
trace.methodEntered=true
trace.methodExited=true
trace.classLoaded=true
trace.errors=true
trace.hprof=false
trace.hprof.tempfile=mydump.hprof
trace.hprof.frequency=6

trace.jmx=true
trace.jmx.configfiles=jmx
trace.jmx.default.frequency=6

And the output I get is

can you post a copy of the jmx.xml config you are using ?

Am posting only part because of character restriction of comments. I havent made any changes to jmx.xml. I went through the site but as I couldnt get what are the minimum changes that need to be done - I didnt attempt it.

I'm going to release an updated version to github. The JMX logic is a port of the engine from the Splunk for JMX app. When running in embedded mode with the SplunkJavaAgent the GCInfo Object returned from the java.lang GarbageCollector MBean is a different base type , hence the above object dump for the GC Mbean.

You should be able to see tracing details for all classes in the com/myinit package also (presuming those classes are getting classloaded) , the above config looks mostly ok. I'd drop the "agent.userEventTags" if you are not using it.
