Go to SolutionvFoglight calculates logical disk space different
Hi there,
I found out that I have several logical disks on virtual machines, where vFoglight does not take the whole capacity, e.g. I have a virtual machine assigned a 40 GB disk, which is showing up in vFoglight with 39,9 GB. Does anybody had this issue also and probably help me out ?
Interesting is that this does not happen on all disks !
Best regards

I found that vFoglight does only report on logical disks with given drive letters, e.g. Windows 2008 you have a system partition which has no drive letter assigned, so vFoglight does not report or calculate it.
So I'm thinking about reporting about the size of the vmdk file associated to a virtual machine, anyone an idea about that ?hEINER
Hi Matthias,
thanks for the answer. That was what I already assumed.
Any Idea about question 2: "So I'm thinking about reporting about the size of the vmdk file associated to a virtual machine, anyone an idea about that ?"

Also I'm thinking that no one of Quest support team ever reads these forum posts, as I have already 3 or 4 different posts not even answered...

Hi,
found the answer on my own. To calculate the really used disk space of a virtual machine, you need to calculate the size given in the vmdkFileLayouts.
I'm using a groovy script for that:
Parameter: vm Monitoring:VMWVirtualMachine
vm = args['vm'];
vmdkList = vm.get("vmdkFileLayouts");
def total = new Double("0");
for (vmdk in vmdkList)
{
total += vmdk.get("diskSize",specificTimeRange);
}
return total/1048576;
Giving the total used disk space of all vmdk files for that virtual machine in MB.
