When you create a custom group, and assign a policy to the group, vRealize Operations Manager can use
the criteria dened 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 seings in the policy.
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 aributes.
When you apply a policy to an object group, vRealize Operations Manager uses threshold seings, metrics,
super metrics, aributes, properties, alert denitions, and problem denitions 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.
n
To associate a policy with the custom object group, select the policy in the group creation wizard.
n
To not associate a specic 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 congured
seings 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 boom 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
dierent policy to each object group, vRealize Operations Manager associates the highest ranking policy
with that object.
User Scenario: Creating Custom Object Groups
As a system administrator, you must monitor the capacity for your clusters, hosts, and virtual machines.
vRealize Operations Manager must monitor them at dierent service levels to ensure that these objects
adhere to the policies established for your IT department, and discover and monitor new objects added to
the environment. You will have vRealize Operations Manager apply policies to the object groups to analyze,
monitor, and report on the status of their capacity levels.
To have vRealize Operations Manager monitor the capacity levels for your objects to ensure that they adhere
to your policies for your service levels, you will categorize your objects into Platinum, Gold, and Silver
object groups to support the service tiers established.
You will create a group type, and create dynamic object groups for each service level. You will dene
membership criteria for each dynamic object group to have vRealize Operations Manager keep the
membership of objects current. For each dynamic object group, you will assign the group type, and add
criteria to maintain membership of your objects in the group. To associate a policy with the custom object
group, you can select the policy in the group creation wizard.
Prerequisites
n
Know the objects that exist in your environment, and the service levels that they support.
n
Understand the policies required to monitor your objects.
n
Verify that vRealize Operations Manager includes policies to monitor the capacity of your objects.
Procedure
