Using Tags and Attributes with Policies

When creating a policy, you first select a data source. Then you can use Tags and Attributes to identify compute instances within the data source to which the policy should apply. If you don't use tags and attributes to narrow the list of affected instances, then the policy applies to all compute instances in the data source.

With tags and attributes you can include or exclude resources based on factors such as the resource name, resource owner, availability zone, region, application, etc. Using tags and attributes you reduce the scope of the report output so it is more focused on the information you want to view. For example, you can filter the report to display only compute instances tagged with the availability zone sa-east-1 and the application DNS.


If no guest diagnostic metrics are enabled, Virtana Platform cannot collect memory utilization details, so recommendations will be based on an assumed percentage. We recommend installing the CloudWatch Agent on EC2 instances to receive more accurate right sizing recommendations.

When selecting a data source, you can include one, multiple, or all cloud provider data sources under a single policy. If you select a parent data source, any linked children are also associated with that policy.
