VMware Cluster VMs Capacity report

We just started evaluating Foglight for capacity planning and assessment. One of the reports I believe our leadership will be interested in is the "VMware Cluster VMs Capacity" report. I see the report provides a value for VMs remaining. I'd like to know a little more about this value and how it is calculated:

  1. What exactly does a "VM" represent in these reports?
  2. Can a similar report be run using a specific type of server based on resource allocation or modeled after an existing VM's wokload?

We will have a small, medium, and large VM offering depending on resource allocation. I'd like to alter the report to display how many of each type of VM I would have available....or point to an existing VM and, based on it's resources and workload, determine how many of that server I have available.

It's based on the average size of the VM in the cluster.  If you look at the Capacity Management dashboard in the UI it can give you more details per cluster.  It's based on the average of the min/max/avg utilization across all the VMs in a given period of time (usually 90 days).  This cannot be changed today, but there is work being done to allow for you to specify a slot size for something like small/medium/large/etc... 

That functionality does however exist in the Foglight for Virtualization, Standard Edition.  It might be worthwhile to look at that if you need it sooner.

Thanks for the information Thomas. At this company, I'm more of a consumer of the service than an implementer. Haven't used Foglight since before Quest acquired it.

Could you provide detial about "Foglight for Virtualization, Standard Edition"?  We are collecting from the virtual infrastructure but, not clear what we are running. Below is the version and build information for our implementation.

The standard edition is the legacy VKernel product that Quest acquired about 2 years ago.  It's not running on the Foglight (Forge) platform, so it would be a seperate virtual appliance you would download and run.  You can see more details about it here.
