Class DefaultNamer

java.lang.Object

com.lightbend.cinnamon.chmetrics.reporter.namer.DefaultNamer

All Implemented Interfaces:

Namer

public class DefaultNamer
extends java.lang.Object
implements Namer

Default metric key naming starts with the descriptor category, then includes all visible and non-unique parts of the identity using pairs of identity category and name, and then adds the descriptor key.

For example, using the default formatter, an actor will have the following metric key:

 "metrics.akka.systems.<system>.dispatchers.<dispatcher>.actors.<actor>.<metric>"
