List number of vm's created and deleted - past month

    Hi Guys

I've found several article about this but i seem to end up with one of 2 results.

1. All of the queries return no results - just end up at the next prompt with no errors.

     Report of list of VM's created in the last year.

2. Endless issues with the script trying to open exls.

Does anybody have a simple query that can show the list of new vm's for the last 30 days and a list of delete vm's for the past 30 days

Our entire environment is on 5.1 U1a and using PowerCLi 5.1 Release 2

Thanks

Johan
