A custom object group is a container that includes one or more objects. vRealize Operations Manager uses custom groups to collect data from the objects in the group, and report on the data collected.

Why Use Custom Object Groups?

You use groups to categorize your objects and have vRealize Operations Manager collect data from the groups of objects and display the results in dashboards and views according to the way you define the data to appear.

You can create static groups of objects, or dynamic groups with criteria that determines group membership as vRealize Operations Manager discovers and collects data from new added to the environment.

vRealize Operations Manager provides commonly used object group types, such as World, Environment, and Licensing. vRealize Operations Manager uses the object group types to categorize groups of objects. You assign a group type to each group so that you can categorize and organize the groups of objects that you create.

Types of Custom Object Groups

When you create custom groups, you can use rules to apply dynamic membership of objects to the group, or you can manually add the objects to the group. When you add an adapter to vRealize Operations Manager, the groups associated with the adapter become available in vRealize Operations Manager.

  • Dynamic group membership. To dynamically update the membership of objects in a group, define rules when you create a group. vRealize Operations Manager adds objects to the group based on the criteria that you define.

  • Mixed membership, which includes dynamic and manual.

  • Manual group membership. From the inventory of objects, you select objects to add as members to the group.

  • Groups associated with adapters. Each adapter manages the membership of the group. For example, the vCenter Server adapter adds groups such as datastore, host, and network, for the container objects in the vSphere inventory. To modify these groups, you must do so in the adapter.

Administrators of vRealize Operations Manager can set advanced permissions on custom groups. Users who have privileges to create groups can create custom groups of objects and have vRealize Operations Manager apply a policy to each group to collect data from the objects and report the results in dashboards and views.

When you create a custom group, and assign a policy to the group, vRealize Operations Manager can use the criteria defined in the applied policy to collect data from and analyze the objects in the group. vRealize Operations Manager reports on the status, problems, and recommendations for those objects based on the settings in the policy.

Note:

Only custom groups defined explicitly by users can be exported from or imported to vRealize Operations Manager. Users are able to export or import multiple custom groups. Once an import function has been executed, the user must check to determine if a policy or policies should be associated with the imported group. Export-import operations are available for user defined (created explicitly by user) custom groups only.

How Policies Help vRealize Operations Manager Report On Object Groups

vRealize Operations Manager analyzes the objects in the object group and reports on the workload, capacity, stress, anomalies, and faults of the object group, among other attributes.

When you apply a policy to an object group, vRealize Operations Manager uses threshold settings, metrics, super metrics, attributes, properties, alert definitions, and problem definitions that you enabled in the policy to collect data from the objects in the group, and report the results in dashboards and views.

When you create a new object group, you have the option to apply a policy to the group.

  • To associate a policy with the custom object group, select the policy in the group creation wizard.

  • To not associate a specific policy with the object group, leave the policy selection blank. The custom object group will be associated with the default policy. If the default policy changes, this object group will be associated with the new default policy.

vRealize Operations Manager applies policies in priority order, as they appear on the Active Policies tab. When you establish the priority for your policies, vRealize Operations Manager applies the configured settings in the policies according to the policy rank order to analyze and report on your objects. To change the priority of a policy, you click and drag a policy row. The default policy is always kept at the bottom of the priority list, and the remaining list of active policies starts at priority 1, which indicates the highest priority policy. When you assign an object to be a member of multiple object groups, and you assign a different policy to each object group, vRealize Operations Manager associates the highest ranking policy with that object.
