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.
Identify the Source of Performance Degradation Through Heat Maps
Identifying the source of a performance problem in vCenter Operations Manager involves investigating cluster
and host health heat maps.
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 Host Health Sized By Workload Grouped By Datacenter/Cluster.
4 Click the Host Health Sized By Workload Grouped By Datacenter/Cluster view.
5 In the heat map, point to the cluster area to view the percentage of remaining capacity.
A color other than green indicates a potential problem.
6 Click Details for the ESX host in the pop-up window to investigate the resources for that host.
What to do next
Adjust workloads to balance resources as necessary.
Identify Datastores with Space for Virtual Machines
Identify the datastores that have the most 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 datastore space.
Option Action
Focus Area
Select Storage.
Smallest Box Shows
Select Datastore.
Description
Select Datastore Space Contention Sized By Total Space Grouped By
Datacenter.
