6 On the Details tab, review the Resources pane and the Workload graphs to assess the potential capacity
for new virtual machines.
If one or more resources of the host are approaching their limits, you might not want to add a virtual
machine to this ESX host.
What to do next
If the selected ESX host has enough resources, you can add the new virtual machines.
Find a Cluster that Has Resources Available for More Virtual Machines
If the vCenter Server host uses Distributed Resource Scheduler (DRS), you can use the Scoreboard tab to check
the available resources in each cluster and make decisions on moving virtual machines in your virtual
infrastructure.
Prerequisites
Verify that you are logged in to a vSphere Client, and that vCenter Operations Manager is open.
Procedure
1 In the inventory view, click the datacenter that contains the cluster that you want to assess, and click the
Environment tab.
2 On the Scoreboard tab, select Health from the View drop-down menu.
The colored bubbles in the Custom Overview chart represent the health scores for all objects in the
datacenter that are online. The workload is represented by the X-axis.
The objects with highest workload appear to the right on the X-axis.
3 (Optional) To filter object types out of the Custom Overview chart, click their icons.
4 In the Custom Overview chart, click the bubble of a cluster that you think might accommodate more virtual
machines.
Usually, this is a cluster that is situated closer to the Y-axis.
The name of the cluster becomes highlighted in the Members List pane.
5 In the Members List pane, click the object name to open its Details tab.
6 On the Details tab, review the Resources pane and the Workload graphs to assess the potential capacity
for new virtual machines.
If one or more resources are approaching their limits, you might not want to add a virtual machine to this
cluster.
What to do next
If the selected cluster has enough resources, you can add the new virtual machines.
Ranking the Health, Risk, and Efficiency Scores
On the Scoreboard tab, you can compare the scores of the Health, Risk, and Efficiency badges and their sub-
badges for child objects that are directly related to the object selected in the inventory pane.
Each child object is displayed as a circle in the Custom Overview chart. Larger circle size means higher score
for the badge that is selected in the Size drop-down menu.
When you compare the Health scores, you can find health problems and see why the health has degraded.
You can also identify groups of objects that might have similar problems, check whether the workload is high
in the selected population, and whether the population has a lot of faults or anomalies.
