VMware Asset Discovery Inspectors

Hello

Using Notepad++ to view the VMwareAssetDiscoveryPlugin 1.4.19 Inspector file. There are a number of interesting items in the file That I am not seeing being reported. For example The various usage statistics, the snapshot inspectors, the virtualization inspectors for disk for Guest VM, are all examples of items NOT being reported. The account we are using to connect to the vCenter has read permissions. I believe I have every analysis enabled. Many fo the properties Not being displayed are items we would like to be able to return as they can be very useful. Not sure what we maybe missing. Is there something additional that is required from the account we are using on the vmware configuration side? Any advice would be appreciated. Thank you.
