Virtual Environment - Esxi 4.0
I have a virtual environment I am trying to trouble shoot, on one of the host machines the memory % is maxed out. I am having users that are having memory issues, example can't send an email not enough memory. I have check that particular server and it's using low memory.
How can I tell what is eating up all my memory on the host?
Thanks

This particular host has 8 virtual machines, all xenappvm servers.
memory on this host is 73717.3 mb
725531 mb to virtual machines
1186.3 mb to the system.
I have checked the summary in VSphere and during this period of time while having this issue the memory is pegged out.
How can I tell what or which server is using it?

There our Application servers serving how many concurrent users per server, what are the properties of the Virtual Machines? CPU, Memory?
If you highlight the virtual machine, and select the Performance Tab, and check Resource Allocation and Summary Sheet.
So you allocate 8-9GB per machine?

servings between 8 - 10 users each server.
each vm server is allocated for 8192 MB
CPU's 2
memory over head is at 340.50 MB

do you need 8G per server for 8 users?

That's what was determined we thought we would need. We are running Exchange 2010 with office 2007, Outlook is a killer on the memory. But when Iook at the individual servers nothing stands out, none of the servers are really maxed out on memory. But I have noticed just moving around the VSphere client from server to server is slow. This morning I am looking at the performance tab, of course there is only 2 or 3 people in at this time but the memory percentage is at 20%, later today when things start to slow down the percentage will go up to 35 %. The chart goes from 17.5 to 35 percent so it's almost maxing out on the chart.
I am going to shut down one of the servers today on the host that I am having issues with and see if that helps.
Any other suggestions of finding out what is using the resources.

Got it... I will check into that.
just spotted should read "you cannot shrink the memory on the VMs".
How much memory does the host server have?
How much memory is allocated to the Virtual Machines?
Maybe you need to increase the memory in the host?
Look at the Summary in vSphere client for VMs using memory, check performance CPU and Memory charts.
