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.
