There are many occasions when you may need to produce a report showing some aspect of your VM environment.

Many companies have various types of inventory databases which grab information from various sources to provide tracking and reporting of the various IT assets.

An example of a database could be one which pulls information from the software inventory system, patch management system, anti-virus console showing latest file update, AD etc. which could show a dashboard view of the workstations and highlight where they are not in compliance to company standards.

As a virtual workstation environment grows there is plently of information from vCenter that would be very useful to gather.

Grouping VMs by VDI groups in vCenter folders so you know how many VMs x department has would be useful to have. For the dashboard view it may be usedful having the VM Tools status. It’s could also be useful knowing which VMs are in which cluster and datastore, what virtual CPU and RAM they have and how big their disks are which can be used for capacity planning, performance analysis and reporting on what is deployed where.

A daily PowerCLI report can then be run which pulls this all from vCenter and dumps a .CSV file which the workstation database sucks in and mashes together with the other feeds providing a single place to view everything related to workstations.

The script builds an always useful hash table which is very easy to add to and then exports the resulting report to CSV.

The Get-Member powershell command is the best way to find out what information is available for a particular object. There are two simple lines you can run which will output most of the objects you can report on, for this example it is Get-VM but you could use Get-Cluster etc.

Get-VM "AnyVM" | Get-Member Get-VM "AnyVM"| Get-View | Get-Member

I’ve also used the great Get-FolderPath function from Maish which is excellent.
