Measures reported by ClusterGroupTest

A resource group is a collection of resources, managed by the Cluster service as a single, logical unit. This logical unit is often referred to as a failover unit, because the entire group moves as a single unit between nodes. Resources and cluster elements are grouped logically according to the resources added to a resource group. When a Cluster service operation is performed on a resource group, the operation affects all individual resources contained in the group. Typically, a resource group is created that contains the individual resources required by the clustered program. Cluster resources may include physical hardware devices, such as disk drives and network cards, and logical items such as IP addresses, network names, and application components.

The ClusterGroups test indicates the current status of the resource groups.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Group_online Indicates the number of resource groups in the cluster that are currently online. Number  

Group_offline Indicates the number of groups in the cluster that are currently offline. Number This count includes only those groups in which all resources are offline.

Group_partially_online Indicates the number of groups in the cluster that are partially online. Number This count includes only those groups in which some resources are online and some offline.
