When [the Prometheus cluster integration is enabled](../../../clusters/integrations.md#prometheus-cluster-integration), GitLab monitors the cluster's health. At the top of the cluster settings page, CPU and Memory utilization is displayed, along with the total amount available. Keeping an eye on cluster resources can be important, if the cluster runs out of memory pods may be shutdown or fail to start.
