Version 2.14 release notes

Grafana Labs is excited to announce the release of Grafana Enterprise Metrics (GEM) 2.14, which is built on top of Grafana Mimir 2.14.

GEM 2.14 inherits all the features, enhancements, and bug fixes that are in the Grafana Mimir 2.14 release. Given this, it’s best to start with the Grafana Mimir 2.14 release notes.

Features and enhancements

Grafana Enterprise Metrics 2.14 adds the following new configurations:

Configuration to set timeout for query request and label names and values requests in Cross Cluster query federation.
Internal gateway gRPC proxy clients can now have their maximum send and receive size limits configured via proxy.grpc-max-recv-msg-size and proxy.grpc-max-send-msg-size config flags.
Two new command line options, -auth.pass-access-policy-name and -auth.pass-token-name, that enable sending the query author’s access policy name and token name to the downstream query services with request headers. The GEM query-frontend can choose to log the X-Access-Policy-Name and X-Token-Name headers in the query statistics logs, via its query-frontend.log-query-request-headers config flag.

Upgrade considerations

This release also inherits the upgrade considerations from the Grafana Mimir 2.14 release.

After you upgrade to GEM 2.14, upgrade your GEM plugin to the latest version. For more information about the most recent enhancements and bugfixes in the GEM plugin, see the Grafana Enterprise Metrics: Changelog.

Deprecations

The experimental support for Redis caching is now deprecated and set to be removed in the next major release. You are encouraged to switch to Memcached.

Bug fixes
