2 In the heat map gallery, narrow the scope from the drop-down menu to display the virtual machines with
waste across datastores.
Option Action
Focus Area
Select Storage.
Smallest Box Shows
Select VM.
Description
Select VM Sized by Space Usage Grouped By Datastore.
3 Click the VM Sized by Space Usage Grouped By Datastore view.
4 In the heat map, point to each virtual machine to view the waste statistics.
5 If a color other than green indicates a potential problem, click Details for the virtual machine in the pop-
up window to investigate the disk space and disk I/O resources.
What to do next
Identify the red, orange, or yellow virtual machines with the highest amount of wasted space.
Identify the Host and Datastore with the Highest Latency
Identify the host and datastore pair with the highest latency to prevent a potential performance problem.
The heat map statistics for host I/O contention measure the latency or the time it takes to gain access to a
resource.
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 waste.
Option Action
Focus Area
Select Storage.
Smallest Box Shows
Select Host.
Description
Select Host I/O Contention Sized by I/O Usage Grouped By Datastore.
3 Click theHost I/O Contention Sized by I/O Usage Grouped By Datastore view.
4 In the heat map, point to each datacenter area to view the latency statistics.
What to do next
Identify the host and datastore pair with the highest latency. Then determine how many hosts are using the
datastore. If only one VM is using the datastore, or if more than one is but none of the others have high latency,
there might be a problem with the host. Find out which VMs are on the host and what their storage usage is.
If there are multiple hosts and they all are red, there might be a population pressure problem on the datastore.
If this is the case, you should consider relocating some VMs.
