In VMware vRealize Operations, policies determine how objects are analyzed and managed. They include settings for metrics collection, alert definitions, symptoms, recommendations, and more. If an administrator disables some virtual machine metrics in the Production policy, only objects assigned to that specific policy will be affected. The changes won't impact other policies or globally affect all objects. This is because policies are hierarchical and inherit settings from their parent policies, unless overridden by the child policies. In the exhibit, the Production policy and the TestDev policy are both child policies of theCompany default policy, which is a child policy of the vSphere solution's default policy, which is a child policy of the Base settings.
Therefore, any changes made to the Production policy will only apply to the objects assigned to that policy, and not to the objects assigned to the TestDev policy or any other policy. References:
