## 12.10. Cluster Monitoring

A Cluster Monitor page may be available in the Jobs section if EKM is being deployed on the ANSYS Enterprise Cloud, or integrating with a visualization server or cluster.

### Monitoring an HPC Cluster

The HPC tab is available on the Cluster Monitor page if an administrator has configured CycleCloud in the ekm.xml file (see the `clusterMonitors` setting in Specifying Remote Process Policies (<remoteProcess>) in the Administration Guide).

Information about individual node arrays is gathered from CycleCloud and displayed in graphs on the HPC tab:

Each graph shows the following metrics:

- Not started: Idle nodes that can be brought up if required.

- Starting: Nodes that are being brought up but are not yet ready to use.

- Started: Nodes that have been brought up and are ready to use.

- Busy: Nodes that are currently being used.

The number of Available nodes is displayed at the center of each graph. This value is the combined sum of nodes that are Not Started, Starting and Started.

Note: Cluster monitors will not be displayed if the administrator has not specified credentials for accessing CycleCloud. If you encounter this issue, contact your administrator.

### Monitoring a Visualization Server or Cluster

The Visualization tab is available on the Cluster Monitor page if EnginFrame is using the Neutro job scheduler to start a remote visualization session on a visualization server or cluster. It shows graphs for the overall cluster status, and visualization hosts categorized by tags. If a node does not have a tag, it will be categorized by its memory, as shown in the example below:

Each graph shows the following metrics:

- Not started: Idle nodes that can be brought up if required.

- Started: Nodes that have been brought up and are ready to use.

- Busy: Nodes that are currently being used.

To monitor usage in busy visualization instances, click in the upper right corner of the view window. This displays the Busy Visualization Instances dialog box, where you can see who is using each instance:
