**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:

I use -javaagent flag to attach elastic-apm-agent to my java process with command:

start C:\ProgramData\Oracle\Java\javapath\java.exe -javaagent:C:\Tools\apm\elastic-apm-agent-1.8.0.jar -Delastic.apm.environment=xxx -Delastic.apm.service\_name=xxx -Delastic.apm.server\_url=xxx -Xmx512m -Delastic.apm.secret\_token=xxx -jar xxx.jar

the problem is elastic-apm-agent inherit -Xmx flag from the application, is there a way to set -Xmx different for elastic-apm-agent? E.g. -javaagent::-Xmx256m

**Steps to reproduce** :  
1.

Hi and thanks for your question.

The agent runs within the same JVM as your application, not in separate one, thus it shares the same heap configuration with your application.
