Hello,
I have the 'VM snapshot size (GB)' alarm enabled on my cluster. I have the warning threshold set to 7GB and the alert threshold set to 10GB. I took a single snapshot of a virtual machine. vCenter is now sending me alerts stating that the 'Metric Overhead due to delta disk backings = 10,989,862KB'. I browsed the datastore on which the virtual machines lives and noticed that the vmname-000001.vmdk (the virtual machine disk snapshot) is only 148,000KB. Why am I receiving this alert?
Thanks in advance,
Steve
