    Cluster utilization #

    Cluster utilization lets you analyze CPU usage, memory, and size metrics of your cluster deployments. To access the cluster utilization view, click the cluster name in the cluster list. 

    Cluster utilization details are not available for free clusters and are only accessible to the owner of the cluster or to roles with administrative privileges.

    Top row #

    The top row of the cluster utilization pane shows the name of the cluster, a Connection info button, and an options menu. For currently suspended clusters, there is also a Resume button.

    If the cluster is currently running, the Resume button does not display.

    Click Connection info to view and copy the connection strings required to connect to this cluster from various client programs.

    The options menu provides the following actions:

    • Query: Opens the query editor using the current cluster as context.
    • Resume: For suspended clusters, lets you resume the cluster.
    • Edit cluster: To edit the cluster.
    • Change owner: To change the owner of the cluster to a different role.
    • View cluster activity: To view the recent activity of a running cluster.
    • Delete cluster: To delete the cluster.

    Cluster attribute row #

    The shaded row of cluster attributes includes the following:

    • Status: The cluster’s current status.
    • Catalogs: Lists the configured catalogs used in the cluster.
    • Cloud provider region: Shows the cloud provider and region.
    • Size: The configured cluster size.
    • Auto suspend: The configured time for an inactive cluster to automatically transition to suspended status.
    • Execution mode: Standard, Fault-tolerant, or Accelerated.
    • Owner: The role that owns the cluster.
    • Enabled: The toggle switch to enable or disable the cluster.

    Cluster metrics #

    • Use the drop-down menu in the Dates field to filter cluster activity by date. If no graphs are drawn, select Last 30 days or longer.

    • When the End date is in the future, the cluster metrics automatically update every 15 seconds.

    • Analyze metrics with the following charts:

      • The CPU usage chart shows CPU usage of the cluster system.

      • The Memory chart shows the memory usage of the cluster.

      • The Cluster size chart shows the number of running workers.
