VMware Performance Monitoring (Windows 2008 page file)

[VCPGuru]

Today one of my VMs filled up the memory and the Windows 2008 host wrotes a lot of memory to the pagefile.

In VMware under Memory usage only 40% was shown as used memory.

In esxtop I switched to memory but didnt found any counter which indicates that the VM was swapping inside the OS.

Under esxtop the MEMSZ was 4096, SZTGT = 4300, TCHD = 1600, %ACTV = 26%

How could I monitor if a VM is swapping memory inside the OS? Powershell?

Thank you in advance!

You really only have 2 choices to do this:

1) you can monitor pagefiel usage from the guest, as you suggested. Perfmon should be adequate for this, and be able to provide more useful information. I would consider monitoring the Process objects and their page faults and pagefile bytes counters to find out which procs are paging.

2) you can put your pagefile on a dedicated VMDK and somehow monitor that file. This will only give you system-wide IO information to that volume.

Happy virtualizing!

Hello.

The Paging File: % Usage and Paging File: % Usage Peak counters in the native Perfmon could be used.

Good Luck!
