Version 2.16 release notes

Grafana Labs is excited to announce the release of Grafana Enterprise Metrics (GEM) 2.16, which is built on top of Grafana Mimir 2.16.

Features and enhancements

Grafana Enterprise Metrics 2.16 adds support for partial queries to cross-cluster query federation. It also including the following changes:

Cross-cluster query federation: increase default proxy target timeout to two minutes. This brings it into line with other similar timeouts such as -querier.timeout.

Upgrade considerations

This release also inherits the upgrade considerations from the Grafana Mimir 2.16 release.

After you upgrade to GEM 2.16, upgrade your GEM plugin to the latest version. For more information about the most recent enhancements and bug fixes in the GEM plugin, see the Grafana Enterprise Metrics: Changelog.

Deprecations

Admin API: Deprecate -admin-api.limits.enabled and default to false in preparation for removal. You should change this to true if you want to continue using the Admin API for limits management.
Remove experimental Datadog proxy.
