Fetch detailed Metrics data of non-Spring Java application

I am using JMX Server, to fetch Metrics data of my application running at Karaf container.

JMX exporter server used: https://github.com/prometheus/jmx_exporter

I tried with Sample Spring application, using Micrometer dependency, the Metric logs were very detailed, bearing data about the number of requests, etc data.

But, my target application is not based on Spring. [It runs on Talend]

The logs I received over this, do not show any data about the number of REST requests received by the application.

What additional/alternative should I do, to fetch more details, like Number of requests, etc ?

Metrics logs received for my application:
