Can we use kamon for multiple java application metrics?

[sali...@gmail.com]

Hi.

Multiple akka applications are running on the server.I want every app to throw a kamon metric.when I run applications at the same time, I get error "Address already in use".How do I fix the error.

app1:

INFO . | Started the embedded HTTP server on http://0.0.0.0:9095 | k.p.PrometheusReporter | [akkaSource] | [kamon.prometheus.PrometheusReporter] 

app2:

ERROR. | Metric reporter [kamon.prometheus.PrometheusReporter] failed to start. | k.ReporterRegistry | [akkaSource] | [kamon.prometheus.PrometheusReporter] 

java.net.BindException: Address already in use (Bind failed)

You need to set the Prometheus port of the second app to a different value using the 'kamon.prometheus.embedded-server.port' property
