Configure Grafana Enterprise Metrics

From the Grafana Helm chart point of view, the main differences between Grafana Mimir and Grafana Enterprise Metrics (GEM) are:

  • GEM requires a valid license.
  • Instead of using NGINX as the router of requests to internal components, GEM deploys its own enterprise gateway component that authenticates and routes requests.
  • More mandatory and optional components are available, such as the admin API and various proxies.

Before you begin

  • Follow the instructions and Choose a name for your GEM cluster.

    It is recommended, but not required to use the same name as the Helm release. For example if the cluster name is mygem, you’d install the chart with helm install mygem grafana/mimir-distributed.

  • Follow the instruction in Get a GEM license to acquire a license.

Handling the license file

There are two options:

  • Provide the license as a value for the license.contents Helm value.

    Either on the command line for the helm command as --set-file 'license.contents=./license.jwt' or by writing the contents into your custom values:

    yaml 
    license:
  contents: "iyJhbGci..."

  • Store the license in a Kubernetes Secret.

    In this case use the following custom values:

    yaml 
    license:
  external: true
  secretName: <name-of-your-secret>

Enable GEM in the configuration

Add the following value to your custom values:

yaml 
enterprise:
  enabled: true

If you want to use a different cluster name for the license and a different Helm release name on the command line, also set:

yaml 
mimir:
  structuredConfig:
    cluster_name: <cluster-name-in-license>
