Hello, you will only be able to use New Relic if your environment is Mendix Cloud or on premises. In other environments such as Kubernetes, it is not possible, since Java Agents do not respect the settings for security reasons.
Here is the documentation for Mendix Cloud https://docs.mendix.com/developerportal/operate/newrelic-metrics/
And here for on-premises - https://docs.mendix.com/developerportal/deploy/setting-up-monitoring-with-new-relic/
