Prometheus Exporter

[GoutamVerma]

Hello Everyone,

In order to implement exporter for Prometheus,
-First I have taken a look at implementation of Kamon(Kanela agent) and traced up the coding part of it.
-Then Instead of creating new object. I have added the Prometheus code stuff in Metrics and Monitoring object.
-At initial point, I will scrape metrics of "balance".

Note: All Prometheus libraries and classes are stored in io.prometheus.client.Gauge and in our code base we have another package named "io" which consist client, clientspawner, etc. The problem is when I build our complete code It will show error

error: object prometheus is not a member of package io  
[ERROR] import io.prometheus.client.Gauge

According to me this error is due to naming convection or dual name of name thing.

Please comments your views!

That doesn't matter at all, the full namespace is fr.acinq.eclair.io so it doesn't clash in any way with io.prometheus.xxx.
I suspect that the error you're having is because you didn't add the prometheus package to the pom.xml file, did you?
Did you add the <dependency> tag to pom.xml as indicated in the Kamon documentation here: https://kamon.io/docs/latest/reporters/prometheus/ ? Don't forget that we're using Maven, not sbt, so you need to follow the Maven documentation.

Yes mentor, I have already added the package to the pom.xml file and in project structure.
But now the issue is resolved and yes I have taken a look at https://kamon.io/docs/latest/reporters/prometheus/ .

And also got an exposed metrics on port 9095. But it is exposed by kamon-prometheus

Metrics on port: 9095

One more thing mentor for exposing metrics through client_java. There is three options HTTP, Exporting to a Pushgateway and Bridges.
And I am using HTTP for our project
