The following best practices help you design and use super metrics.
Design super metrics for performance
Avoid calculating large objects or using world level metrics that works on all VMs. Apply to only relevant objects and never apply to all objects.
Make super metrics reusable
Use Depth greater than 1 to allow vRealize Operations to expand higher levels. Use a clear naming convention without including a specific object name but use Function Object Metric Units.
Enabling super metrics only for the relevant policy
Enable super metrics for the relevant policy, not the base policy.
Use group instead of the where clause.
Using group instead of the where clause is easier to understand.
