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](https://github.com/elastic/apm-agent-java/pull/1196).

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](https://www.elastic.co/guide/en/apm/agent/java/current/config-circuit-breaker.html#config-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](https://www.elastic.co/guide/en/apm/agent/java/current/tuning-and-overhead.html#tuning-and-overhead) 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.
