I'd like to use Prometheus' JMX exporter to collect custom application metrics using Prometheus. I have an application that I've packaged into a jar file ApplicationToMonitor.jar
-- it exposes port 8989 and declares Prometheus metrics, but doesn't expose an end-point for prometheus to scrape (from what I've read, the prometheus javaagent takes care of this).
I'm not sure what the configuration.yaml
file should look like. Also, why is it recommended that one use the shaded.io.prometheus
library (and register new metric variables under the default registry) as opposed to the regular io.prometheus
library and not using a registry at all?
I'm referencing the Prometheus JMX exporter documentation, just simply not understanding the aforementioned components.
