Monitor vCLS in Skyline Health


The new vSphere Clustering Services (vCLS) feature is introducted in vSphere 7 Update 1, to create a de-coupled control-plane for the vSphere Distributed Resource Scheduler (DRS) feature.

Skyline Health

Skyline Health helps to monitor the health of the vCLS agent VMs. By default, there are 3 lightweight agent VM's spun up per cluster. When selecting the vCenter Server instance in the vSphere Client and you go to Monitor > Skyline Health, it'll list all the vCLS enabled clusters. The health and status is monitored. If there's an issue with a vCLS control-plane for a specific cluster, an alert will be raised so the VI-admin can start troubleshooting.

If for example, the vCLS agent VM's need to be re-created, the retreat mode procedure can be started.
