3 Click the Which datastores have the most wasted space and total space usage? view.
4 In the heat map, point to each datacenter area to view the waste statistics.
5 If a color other than green indicates a potential problem, click Details for the datastore 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 datastores with the highest amount of wasted space.
Address a Problem with a Specific Virtual Machine
Identifying the cause of a problem with a specific virtual machine involves investigating whether the
problem is because of a constraining environment or because of changes in the guest operating system
configuration.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
Procedure
1 Search for the problematic virtual machine name in the vCenter Operations Manager search box.
2 Check the Health, Risk and Efficiency scores for the virtual machine.
n
If any of the badges are in the yellow, orange or red state, click the badge and investigate the
subbadges.
n
If the problem is because of Health, check the Anomalies badge for changes in expected behavior
and the Workload badge to assess whether heavy resource demand exists.
n
If the problem results from chronic stress, identify the constraining resource, such as CPU or
memory, and click the Stress badge under the Risk pane for more information.
3 Click the Summary tab under the Planning tab to check the trend and forecast of CPU and memory
demand for that virtual machine and the host that stores it.
If the forecast indicates a virtual machine resource demand problem, increase the resources allocated to
the virtual machine.
4 Identify an object candidate to which to move the virtual machines, click the Analysis tab, and select
the CPU or memory focus areas depending on the constrained resource for the virtual machine.
The heat map gallery helps identify cluster or host candidates to which to move the virtual machines.
5 If the problem results from changes to the guest operating system configuration, click the Events tab
under the Operations tab for that virtual machine.
6 Examine the Events graph to see if the guest operating system change events or vSphere events caused
the problem.
The guest change events will have a different icon shape.
Identify the Virtual Machines with Resource Waste Across Datastores
Identify the virtual machines that waste resources because of idle, oversized, or powered off virtual machine
states or because of snapshots.
Prerequisites
Verify that you are logged in to a vSphere Client and that vCenter Operations Manager is open.
