Configuration/Cluster Data Sources page

Contributors netapp-adityaw

The Configuration/Cluster Data Sources page displays information about the clusters that Unified Manager is currently monitoring. This page enables you to add additional clusters, edit cluster settings, and remove clusters.

A message at the bottom of the page indicates how frequently Unified Manager collects performance data from clusters. The default collection interval is five minutes, but you can modify this interval through the maintenance console if you find that collections from large clusters are not completing on time.

Command buttons

  • Add

    Opens the Add Cluster dialog box, which enables you to add clusters.

  • Edit

    Opens the Edit Cluster dialog box, which enables you to edit the settings of the selected cluster.

  • Remove

    Removes the selected cluster and all the associated events and storage objects. After the cluster is removed, it is no longer monitored.


    The cluster, its storage objects, and all associated events are removed, and the cluster is no longer monitored by Unified Manager. The instance of Unified Manager registered with the removed clustered is also unregistered from the cluster.

  • Rediscover

    Forces a rediscover operation of the cluster so you can update the collection of health and performance data.

Clusters list

The Clusters list displays the properties of all the discovered clusters. You can click a column header to sort the clusters by that column.

  • Status

    Displays the current discovery status of the data source. The status can be Failed (Icon for event severity – error), Completed (Icon for event severity – normal), or In Progress (in progress).

  • Name

    Displays the cluster name.

    Note that the name might take fifteen minutes or more to appear after the cluster is first added.

  • Maintenance Mode

    Enables you to specify the timeframe, or “maintenance window”, when a cluster will be down for maintenance so that you do not receive a storm of alerts from the cluster while it is being maintained.

    When maintenance mode is scheduled for the future this field displays “Scheduled”, and you can hover your cursor over the field to display the scheduled time. When the cluster is in the maintenance window this field shows “Active”.

  • Host Name or IP Address

    Displays the host name, fully qualified domain name (FQDN), short name, or the IP address of the cluster-management LIF that is used to connect to the cluster.

  • Protocol

    Displays the type of protocol that can be configured on the cluster: HTTP or HTTPS (for a secure connection).

    If a connection is established with the cluster by using both protocols, HTTPS is chosen over HTTP. The default is HTTPS.

  • Port

    Displays the port number of the cluster.

    If the port is not specified, the default port for the selected protocol is used (80 for HTTP or 443 for HTTPS).

  • User Name

    Displays the user name that can be used to log in to the cluster.

  • Operation

    Displays the current operation that is supported by the cluster data source.

    The following operations are supported by the data source:

    • Discovery

      Specifies the operation when the data source is being discovered.

    • Health Poll

      Specifies the operation when the data source is successfully discovered and has started sampling data.

    • Deletion

      Specifies the operation when the data source (cluster) is deleted from the respective storage objects list.

  • Operation State

    Displays the state of the current operation. The state can be Failed, Completed, or In Progress.

  • Operation Start Time

    The date and time the operation started.

  • Operation End Time

    The date and time the operation ended.

  • Description

    Any message related to the operation.
