Hi All,
Is there a way to monitor and limit memory usage for the java apm agent? I believe this agent is making my java app to run out of memory.
Using:
apm java agent version: 1.16.0
apm-server: 7.8
Thanks
Hi 
If you are using gRPC, you should upgrade the agent at least to 1.17.0 where a related memory leak was fixed.
Measuring the agent overhead is best done by comparing same scenarios/load-tests with and without the agent. Let us know if you see something interesting.
Regarding limiting the agent - there is no memory quota to apply, but you can use the circuit breaker to make sure the agent disables itself if the JVM gets into a heap stress.
In addition, go over the tuning and overhead page to get an idea of what's causing it. If you are using non-default agent configurations, try disabling them to see if there is any specific one related.
