What to do next
To further investigate which resources constrain the virtual machine count, click the Views tab and select the
Virtual Machine Capacity - Summary view.
Identify Clusters with the Space for Virtual Machines
Identify the clusters in a datacenter that have space for your next set of virtual machines.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 Click the Analysis tab.
2 In the heat map gallery, narrow the scope from the drop-down menu to display the remaining capacity
for clusters.
Option Action
Focus Area
Select Capacity.
Smallest Box Shows
Select Cluster.
Description
Select Which clusters have the most free capacity and least stress?.
3 Click the Which clusters have the most free capacity and least stress? view.
4 In the heat map, point to each cluster area to view the percentage of remaining capacity.
5 If a color other than green indicates a potential problem, click Details in the pop-up window to investigate
the resources for the cluster or datacenter.
What to do next
Identify the green clusters with the most capacity to store virtual machines.
Investigating Abnormal Host Health
Identifying the source of a performance problem with a host involves investigating its workload.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 In the inventory pane, select the object that you want to inspect.
2 Click the Analysis tab.
3 In the heat map, narrow the scope from the drop-down menu to display the cluster and host health sized
according to workload.
Option Action
Focus Area
Section Health.
Smallest Box Shows
Section Host.
Description
Section Which hosts currently have the most abnormal Workload?.
4 Click the Which hosts currently have the most abnormal Workload? view.
