Version 2.13 release notes

Grafana Labs is excited to announce the release of Grafana Enterprise Metrics (GEM) 2.13, which is built on top of Grafana Mimir 2.13.

GEM 2.13 inherits all the features, enhancements, and bug fixes that are in the Grafana Mimir 2.13 release. Given this, it’s best to start with the Grafana Mimir 2.13 release notes.

Features and enhancements

GEM has implemented enhanced usage statistics for more accurate reporting.

GEM has followed suit with Mimir 2.13 by limiting Go’s GOMAXPROCS setting to be no more than NumCPU to reduce scheduler overhead.

The grafana/enterprise-metrics docker image is now based on gcr.io/distroless/static-debian12 image. The Alpine-based docker image is still available as grafana/enterprise-metrics-alpine.

Upgrade considerations

With Grafana Mimir 2.13, mimir-continuous-test is no longer a standalone binary and is now part of Mimir as its own target. The published Docker image has been updated to use the new packaging.

The configuration option -log.buffered, deprecated in Grafana Mimir 2.11, has now been removed from Mimir 2.13. Logs are now always written in a buffered fashion.

Bug fixes
