Absolutely you can monitor VMware Tools status - there is an out-of-box Monitor for this built into the nworks MP
it is disabled by default, all you need to do is enable it with an override.
Monitor name is 'nworks VMware: VMware Tools Service Out-of-date'.
When you enable this, you will get a Warning alert for every VM where the VMTools version does not match the build of the ESX Host.
Upgrade the VMTools for a VM, and the alert will automatically close.
Note - there is also a Monitor for 'VMware Tools not running' that you also could find useful.
For Memory Limits - we do capture the memory Reservation
for each VM, but not any Limit settings. I can take that as a feature request for a future update though!
Meantime, if you want really detailed configuration reporting, have you looked at our Veeam Reporter product?
Hope the above help, any questions let me know,
