1. In the first line, click the icon.
The Match drop-down list is displayed.
2. Select Any.
3. Click the icon.
4. Use the drop-down menus to complete the new line:
Type = VMWARE ESX VMGUEST
5. Click the blank area in the Type = MICROSOFT HYPERV VMGUEST line and drag the
expression so that it is just below the Match Any option.
The filter looks like this before the drag-and-drop operation:
After dragging the first row to the sub-expression, the filter looks like this:
6. Click Save to save the revised query.
Example: Reducing licensing costs by finding VMs with one too many cores
Background
The predefined query “VMs with over provisioned vCPUs” checks for virtual machines where the
CPU utilization never goes above 35% utilization. But any VM that matches this query over a long
period of time is probably a good candidate for removing half of its virtual CPUs (vCPUs).
Many IT organizations use the power of two for the number of cores in their virtual machines. This
means they have VMs with one, two, four, or eight cores. Because the overhead for having a few
extra cores in a VM is small, it is reasonable to standardize the number of cores per VM to the
power of two. In terms of savings on the VM host, taking the time to decide if seven cores will
suffice instead of eight cores is generally not worth the effort.
