What is a Clustered Metric?

A Clustered Metric is a Metric set to calculate service levels for a group of Resources. The calculations are done for each of the Resources individually, without the necessity to duplicate the Metric every time with the registration of a different resource.

The clustering can only be done on a group of Resources that either have no target service level attached to it or have the same target service level. For example, the availability of all application servers should be at least 99.9% per server. In this case, a Metric is clustered over a group of resources that contains all application servers. The Engine calculates a separate service level result for each server, where the target for each server is 99.9%.

In addition to this type of clustering, CA Business Service Insight supports a 'roll-up' type of clustering, enabling multiple levels of resource (and group) reporting from a single metric. This enables the service level to be calculated at multiple levels of the resource hierarchy and a drill up/down feature between this resource structure's related entities. From the Metrics Clustering tab, you can enable this option by selecting the relevant options on this page.
