You can monitor the resources consumed by vCLS VMs and their health status.

vCLS VMs are not displayed in the inventory tree in the Hosts and Clusters tab. vCLS VMs from all clusters within a data center are placed inside a separate VMs and templates folder named vCLS. This folder and the vCLS VMs are visible only in the VMs and Templates tab of the vSphere Client. These VMs are identified by a different icon than regular workload VMs. You can view information about the purpose of the vCLS VMs in the Summary tab of the vCLS VMs.

You can monitor the resources consumed by vCLS VMs in the Monitor tab.

Table 1. vCLS VM Resource Allocation
Property Size
VMDK size 245 MB (thin disk)
Memory 128 MB
CPU 1 vCPU
Hard disk 2 GB
Storage on datastore 480 MB (thin disk)
Note: Each vCLS VM has 100MHz and 100MB capacity reserved in the cluster. Depending on the number of vCLS VMs running in the cluster, a max of 400 MHz and 400 MB of capacity can be reserved for these VMs.

You can monitor the health status of vCLS in the Cluster Services portlet displayed in the Summary tab of the cluster.

Table 2. Health status of vCLS
Status Color Coding Summary
Healthy Green If there is at least one vCLS VM running, the status remains healthy, regardless of the number of hosts in the cluster.
Degraded Yellow If there is no vCLS VM running for less than 3 minutes (180 seconds), the status is degraded.
Unhealthy Red If there is no vCLS VM running for 3 minutes or more, the status is unhealthy in a DRS enabled cluster.
