How can calculate how much memory is using by guest OS

I want to see the amount of memory that is using by guest OS . Memory usage is not suitable because is shows memory usage for my VM 95% although in the guest os via linux command free -m show just 2GB is using and most of it is caching thus I think if I want see memory usage from OS had to select Memory Guest Demand

Is that correct ? if no please say which metric can show the how much memory is using by OS

also I was read vrops doc about these metrics but really It did not explain clearly

Can anyone say which metric can exactly say how much memory guest os is using ?

I think Guest memory demand is such as Active memory thus can show how much memory is using for guest os

Is that correct?

Memory|Workload (%) is based on memory usage inside the guest OS (assuming vROps is able to collect the data from VMTools via vCenter)

Check this article;

I've hardly ever seen that vROps and OS show precisely the same amount of memory used. They have a different starting point from which they calculate memory used.

That is correct . Actually there are not any metrics with same value in vROPS  and OS but they are close to each others. but here memory workload , memory usage are 95% although in the OS memory usage is about 2% this is not normal thus I think memory usage or memory workload not relate to guest OS memory

Did you checked Mem|Guest Usage (KB)? If it is not there check in the policy if it is disabled.

Yes. I checked it also it show memory usage is about 90% . but value of memory active is close to guest os  memory usage.

Do you see this on one or many VMs? Also which VMware tools version are you running?

I have the same issue with 1 of my VMs. Memory|Workload% and Memory|Guest (kb) both show 100% usage... whiles on the VM itself Windows is at 60%.

This just happen most on vms with Linux OS and most of them that use vmware tools with guest manage
