= SRE metrics set example

[role="_abstract"]
When you specify the `SRE` metrics set, the HyperShift Operator looks for a config map named `sre-metric-set` with a single key: `config`. The value of the `config` key must contain a set of `RelabelConfigs` that are organized by control plane component.

You can specify the following components:

* `etcd`
* `kubeAPIServer`
* `kubeControllerManager`
* `openshiftAPIServer`
* `openshiftControllerManager`
* `openshiftRouteControllerManager`
* `cvo`
* `olm`
* `catalogOperator`
* `registryOperator`
* `nodeTuningOperator`
* `controlPlaneOperator`
* `hostedClusterConfigOperator`

A configuration of the `SRE` metrics set is illustrated in the following example:
