I am running a server with Windows 2008 Server SP2. The application is working ok, but I'm slightly worried that we're running out of memory.
The server has 4GB RAM. The application installed is a 32bit application, however it has 3 main processes.
I went to Perfmon, and looked at the following counters:
Available Mbyes: Average is 300MB
% Commited Bytes in Use: Average is 22%
Pages/ Sec: Average is 5
Commited Bytes: Average is 2.5 GB
Pages Output/Sec: 0
I've been reading a couple of articles on the Net, and a lot seem to contradict each other!
The later says that if Available Mbytes is less than 20-25% of installed RAM, then we have an issue, but the first one says 5%.
Likewise, for Pages/Sec, the latter says anything higher than 5 is a problem. The second says 1000! Whereas for Pages/ Sec, this article says 40
Could someone confirm?
Basically, I need a reliable counter that will tell me:
i. How much Physical memory I have left
ii. How much memory applications get from RAM as opposed to paging?
Any help appreciated!!!
