I have an example akka application (
https://github.com/Michael-List/akka-microservice-sample/tree/kamon) in which I integrated Kamon 2 and the prometheus reporter. On the Kamon status page on port 5266 I can see that the modules host metrics, jvm metrics, process metrics and status page are successfully started. In the metrics section there is a metric akka.actor.mailbox-size but I can't find this metric on the prometheus server, only other kamon metrics. Could you please tell me what I'm doing wrong? If you need further information please ask me.
