vFoglight 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

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.

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,
vFoglight relies on VMware Tools to retrive the logical disk information inside the guest and it probably only report disk with drive letters assigned as you have pointed out.

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...
