5.5 u2 memory

[verto]

esxi 5.5 u2 host has 65 gb memory and % memory 92 but when i check Virtual machines use less memory . why ? what is wrong

# Memory	Memory usage %	vRAM
65,501	92	196,608

The value vRAM on the image you posted means the total amount of RAM that you have assigned to virtual machine, that based image m1, if you sum all the values from column memory size the total is 196,608.

Of course, the value 196,608 does not means that virtual machine is using (consuming) all that memory, but it is the value that you have as "configured memory" on virtual machine settings.

I advise you read that doc: Memory Counters

By the way your host is quite heavily over commited. With 5GB of ram left and these big VMs I would be concerned.

The risk to hit the thresholds that trigger the memory reclaiming mecanisms is high.

You should have a look at your swap/balloon counters.
