Version 2.8 release notes

Grafana Enterprise Traces (GET) 2.8 uses Tempo 2.8 as its foundation, so it inherits all the features, enhancements, and bug fixes of the upstream project.

Read the Tempo 2.8 blog post for more examples and details about these improvements.

Review the Tempo 2.8 release notes for descriptions of the most notable changes. For a complete list, refer to the Tempo changelog.

GET is fully compatible with Tempo. You can use a GET 2.8 binary in a Tempo 2.8 deployment with minimal changes.

Note

This release has some major upgrade considerations including changing the default http-listen-port from 80 to 3200, removing serverless, and enforcing max attribute size at event, link, and instrumentation scopes.

Refer to Upgrade considerations in the Tempo documentation for details.

Features and enhancements

This release includes the following features and enhancements:

You can configure your spans via standard OpenTelemetry environment variables. For Jaeger exporting, set OTEL_TRACES_EXPORTER=jaeger. This release removes the use_otel_tracer option. For more information, refer to the OpenTelemetry documentation.

In addition, you can now configure metamonitoring to use the K8s-monitoring Helm chart. This change simplifies setting up and configuring metamonitoring for GET. Refer to Grafana Enterprise Traces metamonitoring documentation for more information.
