+ newrelic: add possibility to send akka metrics to the newrelic
Added possibility to send akka metrics to the newrelic as custom metrics.
Externalized categories of newrelic subscription into the configuration file.
This allow to define which metrics categories should be send to newrelic
independent upon which metrics are actually collected.
Akka metrics exported to the newrelic as custom metrics and available in custom
dashboards in some format similar to:
Cusom/akka-actor/{ActorSystemName[user|system|...]\{ActorName}/{MetricName}
for actors and
Custom/akka-thread-pool-executor\Some-Service\akka.io.pinned-dispatcher/ProcessedTasks
for thread pools.
Same metrics for multiple actors can be displayed as a single chart by using *
(star) for part of the actor name. For example
Cusom/akka-actor\MyActor\user\*DatabaseWorker/ProcessingTime
will show processing time for all database workers.
Example of actor metrics displayed by newrelic:
