Prometheus reporter and metrics naming differences with Prometheus client

[leszekgruchala]

Hello,
I am using Kamon 2.5.2 with Prometheus exported in some of my apps. I have also the other app that I use directly Prometheus official java client.

I noticed that not all metrics are named accordingly, for example, Kamon produces jvm_memory_used_bytes (histogram) with the Prometheus exporter, and Prometheus official java client produces jvm_memory_bytes_used (gauge) (source).

Because of such differences, we would need to prepare different Grafana graphs for projects that use Kamon and the official Prometheus library.

Is it possible to make Kamon producing same metrics like an official Prometheus client?

Thank you
