jmx-cnb

The Cloud Foundry JMX Buildpack is a Cloud Native Buildpack V3 that enables the JMX in JVM applications.

Behavior

This buildpack will participate if all of the following conditions are met

• $BP_JMX is set

The buildpack will do the following:

• Contribute JMX configuration to $JAVA_OPTS

Configuration

Environment Variable	Description
$BP_JMX	Whether to contribute JMX support
$BPL_JMX_PORT	What port the JMX connector will listen on. Defaults to 5000.

Creating SSH Tunnel

After starting an application with JMX enabled, an SSH tunnel must be created to the container. To create that SSH container, execute the following command:

$ cf ssh -N -T -L <LOCAL_PORT>:localhost:<REMOTE_PORT> <APPLICATION_NAME>

The REMOTE_PORT should match the port configuration for the application (5000 by default). The LOCAL_PORT must match the REMOTE_PORT.

Once the SSH tunnel has been created, your JConsole should connect to localhost:<LOCAL_PORT> for JMX access.
