Prior to last month everyone was complaining that vsphere is not reading the memeory usage correctly as all virtual machines spike to 90-95%.
Now after the patch that was released a couple of weeks ago, its reporting 5-10% usage. What the heck? thats not possible. Is anybody else seeing this?
We are also experiencing this problem on vSphere ESXi, but only for 64bit W2k8 servers, our Linux boxes are behaving perfectly. FYI, we are running a virtual vCenter, I wonder if this has some bearing?

we got memory usage alarms going on on our ESX servers. when you login into the vm themselves and pull up task manager or perfmon, you see the memory usage, lets say 80-85%. But when you look at the ESX dashboard it reports vm using 5% memory. not making any sense.
Can someone explain how this works?
Hi kfkehua,
Actually what you are mentioning seems to match a certain VMware KB, that describe that Virtual Center report the wrong memory usage for VMs. It report a memory usage way higher than the VM actually need. You can read my following post for more info about this problem & how to resolve it:
Vsphere virtual machine incorrect memory usage report
I hope this help some one, if it does please reward points.
