Measures reported by ClusterNodeTest
Every server in a cluster is referred to as a Node. Using the ClusterNodes test, you can identify how many nodes in the cluster are currently not available.

Measurement
Unit |
Interpretation |
| Up_status |
Indicates the number of nodes that are currently up and running in the cluster. |
Number |
An online node or a node whose status is 'Up', is an active member of the cluster. It adheres to cluster database updates, contributes input into the quorum algorithm, maintains cluster network and storage heartbeats, and can own and run resource groups.
|
| Down_status |
Indicates the number of nodes in the cluster that are currently offline. |
Number |
A node whose status is 'down' or 'offline' is considered to be an inactive member of the cluster. The node and its Cluster service might or might not be running.
|
| Paused_status |
Indicates the number of nodes in the cluster that are paused. |
Number |
This refers to nodes that are active members of the cluster. The node adheres to cluster database updates, contributes input into the quorum algorithm, and maintains network and storage heartbeats, but it cannot accept resource groups. It can support only those resource groups that it currently owns. The paused state enables maintenance to be performed. Online and paused states are treated as equivalent states by the majority of the server cluster components.
