Migration guide

This is a guide for migrating from Lightbend Telemetry 2.15 to Lightbend Telemetry 2.16.

Akka Actor, Remote, and Router metric name change

The identities of some metrics have been changed because of the introduced message-type dimension.

This change affects the existing Akka Actor, Remote, and Router metric dashboards, meaning they will not work with the new Lightbend Telemetry even if the message-type dimension is not enabled explicitly.

We have updated dashboards for Prometheus and Elastic that you can download here. They are also included in the developer sandboxes that we provide out-of-the-box.

If you use some other metric backends, including Datadog and NewRelic, you will need to update your graph queries that use Akka Actor, Remote, and Router metrics. The Metric Dictionary lists all the metrics, including their identities. This is the list of the metrics that have been changed:

Akka Actor metrics

  • Sent messages
  • Processed messages
  • Processing time
  • Remote sent messages
  • Remote sent message size
  • Remote serialization time
  • Remote received messages
  • Remote received message size
  • Remote deserialization time

Akka Router metrics

  • Router routed messages
  • Router processing time
