A little long-winded history (I opened an SR - awaiting feedback) -
So turns out, vROps actually has two different properties (much like RVTools does) to show the VM's Guest OS Type configuration setting and a different one to show the Guest OS as seen by the VMware tools. Unfortunately, the Dashboards, Views, Summary Display, & Reports do not tell you which property they are using in their generic labels. So depending on what and where you're looking in vROps, you could potentially be looking at the wrong thing if you have improperly configured VMs.
For instance, say you build a VM as 2008R2 back in the day, and you did an inplace upgrade to 2012 but forgot to change the Guest OS Type in vCenter to 2012.
Looking at that VM In vROps, "VM > Details > Property|Configuration|Guest Fullname" will show 'Microsoft Windows Server 2008 R2 (64-bit)'.
However, also looking at that VM in vROps, under "VM > Details > Property|Summary|Guest Operating System|Guest OS Full Name" will show 'Microsoft Windows Server 2012 (64-bit)'.
If you look at the VM's Summary page / About Me section, it shows the 'Summary|Guest Operating System|Guest OS Full Name' value.
If you look at that same VM in the default dashboards or canned VM Inventory Summary view, it shows the 'Configuration|Guest Fullname' value. But, you don't know that because a custom label (by VMware-- not me/end-user) was applied to the View to just show "Guest OS" so you don't know what you're looking at unless you edited the view to get the specific property.
It's a major PITA and misleading!
Obviously we need to correct all these so the mismatch doesn't exist in the firstplace; and, I can create a view that shows both properties and then export to xls and filter on ones that aren't equal-- but that's all even more PITA.
I'd like to create a supermetric (call is OSMismatch) that says something like, "if "Configuration|Guest Fullname" != then set OSMismatch = '1'" or something along those lines.
Does anyone know if you can actually DO something like this in a supermetric? ie, compare two properties and set a new boolean value based on the compare results?
