## What it is
The Prometheus JMX Exporter collects Java Management Extensions (JMX) MBean values and exposes them as Prometheus metrics, or forwards them via OpenTelemetry. It can run as a Java agent inside the target JVM or as a standalone exporter scraping over remote JMX/RMI.

## Use cases
- expose JMX MBean metrics to Prometheus
- monitor JVM applications without setting up remote JMX
- attach a metrics agent to an existing Java process
- export Java app metrics via OpenTelemetry
- scrape a remote JVM over JMX/RMI for metrics
- run multiple isolated metric exporters in one JVM

## When to choose
- you need Prometheus metrics from Java applications exposing JMX MBeans
- you want to avoid remote JMX/RMI configuration by using a Java agent
- you need OpenTelemetry output instead of Prometheus scrape endpoints

## When to avoid
- your application does not expose metrics via JMX MBeans
- you monitor non-JVM runtimes like Go, Python, or Node.js
- you need full application performance profiling rather than metrics collection
