I'm having trouble getting prometheus set up with my grails app. I have it completely set up and working with other exporters just don't really know where to go with the actual application.
I am trying to use the jmx exporter found here: https://github.com/prometheus/jmx_exporter
Following the instructions on that page, it seems like the exporter gets attached to a .jar file. But to my knowledge, grails never gets converted to a .jar file? And also there's a difference I know between when grails is running in dev and production where it gets compiled into a .war file. Does there need to be separation in the front and back end? Any information would be much appreciated.

You get to decide if you want to deploy your Grails app as a .jar file. If you are using Grails 3 or 4 the assemble Gradle task will create a .war file if the war Gradle plugin is applied in the project, otherwise an executable .jar file will be created.
And also there's a difference I know between when grails is running in dev and production where it gets compiled into a .war file.
By default, when you generate a .war file (or a .jar file) the app will run in production mode, but you can generate a dev mode .war or a dev mode .jar file if you want to for any reason.

There does not.
