Best practice vSphere view provides detailed visibility of your virtual environment based on vSphere, in terms of clusters, hosts, resource pool, datastores and VMs. This view automatically provides indicators such as “spare capacity” at cluster level and estimated “days to saturation” for hosts, datastores and VMs. Recommendations on how to increase the efficiency (e.g. reduce resources for overallocated clusters or move idle VMs) and reduce the risk (e.g. remove old VM snapshots) are also provided.
