Hi all,
I’ve just downloaded the JVM Instrumentation Agent app to see what kind of metrics I could collect into Splunk.
I did a really simple try with a HelloWorld Java method that I execute once.
I added the agent like mentioned in the README, but get only one event into Splunk, the class loading.
I would have expected to get events for each method call since I have set:
trace.whitelist=com/splunk/tests/AgentTests
trace.methodEntered=true
trace.methodExited=true
Is there something I am missing?
Event I collect:
1455705580195
name=class_loaded
event_id=splunkagent
appName=myapp
appID=myjvm
className=com/splunk/tests/AgentTests
Thanks !!
Romain.
I have to guess here , as I can't see your source code , but it is likely that your test program is exiting before all the events have time to be sent. Try putting a Thread.sleep(10000) in your test code before it exits.
Some good info here also , from slide 38.

I exchanged with Damien offline and it seems that "weaving bytecode instructions for method tracing into the application main class is not performed".
I rearranged my code and everything is ok now !
Thanks Damien,

Hi Damien,
Thanks for your quick answer !
I tried but same result ..
Here is the simple class:
package com.splunk.tests;
public class AgentTests {
public static void main(String[] args) {
try {
System.out.println("====== Say Hello ======");
System.out.println(sayHello(args[0]));
Thread.sleep(10000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static String sayHello(String name) {
return "Hello " + name;
}
}
And the execution:
java -javaagent:"/opt/test-splunk-agent/splunkagent.jar" -jar mytests.jar romain
Romain.
please share your full agent config file.
