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.

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 hEINER
vFoglight calculates logical disk space different
