Turn off call stack sampling?

Hi all

for a specific JVM, I would like to instrument it with the JavaAgent and get memory and JMX metric. But I know that I will never get/want BusinessTranscation data from this JVM, and thus I would prefer to turn off the call stack sampling and avoid the stop-the-world pauses every 10 ms.

Is this possible with a -D argument to the JVM/agent (AppDynamics 4.3.5.7)?

CU, Joe

Joe,

If there are no BTs on your node, it will never do the stack sampling, since its whole purpose is to gather data about slow BTs.

Warm regards,

Peter

Good to know, thanks! I didn't realize that and assumed it would always be active
