= Configuring the TempoStack metrics and alerts

You can enable metrics and alerts of TempoStack instances.

.Prerequisites

* Monitoring for user-defined projects is enabled in the cluster.

.Procedure

. To enable metrics of a TempoStack instance, set the `spec.observability.metrics.createServiceMonitors` field to `true`:
+
[source,yaml]
----
apiVersion: tempo.grafana.com/v1alpha1
kind: TempoStack
metadata:
  name: <name>
spec:
  observability:
    metrics:
      createServiceMonitors: true
----

. To enable alerts for a TempoStack instance, set the `spec.observability.metrics.createPrometheusRules` field to `true`:
+
[source,yaml]
----
apiVersion: tempo.grafana.com/v1alpha1
kind: TempoStack
metadata:
  name: <name>
spec:
  observability:
    metrics:
      createPrometheusRules: true
----

.Verification

You can use the *Administrator* view of the web console to verify successful configuration:

. Go to *Observe* -> *Targets*, filter for *Source: User*, and check that *ServiceMonitors* in the format `tempo-<instance_name>-<component>` have the *Up* status.

. To verify that alerts are set up correctly, go to *Observe* -> *Alerting* -> *Alerting rules*, filter for *Source: User*, and check that the *Alert rules* for the TempoStack instance components are available.
