Metrics for a specific process

kenytux opened this issue 10 months ago · 6 comments

Hello,
I want to get metrics from a specific java application process (Like memory and cpu usage)
Does it possible?

The exporter will provide access to JMX metrics exposed from the Java application process, but you still need/should do application monitoring at the OS level.

For example, if I have an application called myapp, can I have it's memory usage (Like 8gb for myapp)?
Iif it is how I do it?

Yes. Here is a list of built-in Java MBeans:

The documentation (README.md) describes the installation and configuration in general terms, but the nuances are related to your specific application, deployment environment, etc.

I would start with "Running the Agent" https://github.com/prometheus/jmx_exporter?tab=readme-ov-file#running-the-java-agent.
