win2k performance logs

[Draven]

having left performance logs running yesterday and overnight i have these pretty looking graphs

been a while since i did performance logs but to me it says i havent got enough ram which is increasing the swap file usage and extending the disk queu lengths, altho there could be a problem with slow hard disk access aswell

screen grabs of performance viewer log graph attached

what do you guys think?

pretty poor for a dual xeon server with (512) RD-RAM and 10,000 rpm scsi drives isnt it

I agree with your diagnosis, looks like it needs more RAM.

Trouble is with NT and 2000 is that they can swap out anything not used for 7 seconds :eek: , so any app that uses a lot of memory but is idle for a while may be swapped out causing lots of page faults.

If this is just a file and print server that is not used for anything else i would say leave it, access being slightly slower now and then won't matter.

If you are running any apps on it then I'd get more memory, it should increase response.

What size is your page file?
What kind of harddisk setup have you got (RAID0,1,5)?

You say this was running overnight, what else was running? Backup, Virus scanning or some other software?

People often chuck RAM at servers in the hope it solves the problem when it could be something else completely different, i.e harddisk failure if its RAID5.

its not running raid ( :eek: i know i know, cant afford the extra drives on this one) so just straight 3 scsi drives running from an onboard scsi controller

its a webserver and exchange machine that regularly (ish) needs rebooting and suffers explorer corruption (very weird display problems) when the backup has been run
OS is installed on disk 0 swap files are set to 2 gig on both drives 1 and 2 (4 gig swap file total)

it was running during the second half of the day and got left on over night (cos i forgot to turn it off) so standard web serving (all machines have it as their home page) and e-mail services mostly (exchange 2000)

the OS is 2000 server sp4 with updates, exchange sp3 is installed and as of yesterday is running GFI mail security (trial)

You can monitor the Processes that are in memory and are causing the page faults by adding the "Process" object and "Page Faults/sec" to perfmon.

This may help in diagnosing what app is causing the problem.
