Expose java metrics to prometheus

[Nidhi Sharma]

Hi, I have a web app running on tomcat. There is a hello resource (REST API) to check the health of the app. Output if this resource gives the version of the app. I want output of this resource to be captured as a metric and pulled by Prometheus. Please help on how can I proceed.

Thanks for replying. Can we do this by Mbeans and JMX ? I can create Mbeans and register it in my application but I dont know how to capture the output in Prometheus time series format. For ex : Product_version{product="SomeProduct",version="2.9.1"}

Create a metric name as you wanted and add labels to it https://github.com/prometheus/client_java#labels
