The value field in the values.yaml file for your Platform is platform.export.jmx.enabled. Setting this value to true enables the Prometheus server to scrape the JMX metrics from the Platform. Additionally, you can configure a port for your JMX exporter using platform.export.jmx.port and assigning it any port number allows the JMX exporter to expose the metrics on that particular port.

You need to expose the JMX port on your Platform if you have applied the changes to the values.yaml on an already installed Platform. You can use this command to forward the port.

kubectl port-forward <pod name> <arbitrary port>:<jmx port defined in debug.jmx.port>

kubectl port-forward platform-0 30103:8888

This is an example of a values.yaml file where the JMX exporter is enabled for Platform on port 8888.

    jmx:
	  export:
        enabled: true
	    port: 8888
