We get alert in SCOM for High memory pages/sec for 3 Hyper V servers. When we launch Perfmon on server, we noticed that memory pages/sec remains between 40,000-50,000 everyday around same time for 1 hour. For rest of the day, value of this counter remains below thresholds.
How can we further troubleshoot this? Do we need other counters to record?

Were you able to identify the process involved ? ( I am referring to application process )
Get the procmon trace saved , upload to skydrive for analysis.
Usually the Process memory may include both the user mode / kernel mode thread activity ( page table activity ).
How does this impact ? , there might be a specific thread calling for certain network layer drivers to perform the task , or there might be bunch of threads performing CPU related activities , is there any backup / provisioning scheduled during the time ?

We have not done any diagnosis other than launching perfmon for Memory pages/sec.
Can you suggest of any tool/etc that can help identify process responsible for this?
We, do not have any scheduled backups

I would first go with Perfmon tool - which is inbuilt on Server OS .
Configure the necessary counters for memory , CPU , RAM and Network adapter.
If you are seeing the issue at fixed time everyday - use process explorer to check for the CPU spike on specific processes.
Processexplorer can be downloaded from TechNet weblink http://technet.microsoft.com/en-US/sysinternals
From scom end, does the MP provide additional information about the issue ? ( status key words , any refereeing exe / dll ? )
