To enable remote JMX, such as for profiling with VisualVM or JMC, set the environment variable `ENABLE_JMX` to "true", set `JMX_HOST` to the IP/host running the Docker container, and add a port forwarding of TCP port 7091, such as:
```
-e ENABLE_JMX=true -e JMX_HOST=$HOSTNAME -p 7091:7091
```
!!! example
With `docker run`
```
-e ENABLE_JMX=true -e JMX_HOST=$HOSTNAME -p 7091:7091
```
If needing to map to a different port, then also set the environment variable `JMX_PORT` to the desired host port.
!!! example
With a compose file:
```yaml
environment:
ENABLE_JMX: true
JMX_HOST: ${HOSTNAME}
JMX_PORT: "7092"
ports:
- "7092:7092"
```
