performance - identify process

[Bob]

We have an application server running W2k server SP4. IT has four
processors, 4gb of ram.

during business hours, from about 10:00 to 12:30 every day, page faults sky
rocket and disk i/o goes crazy.

what i need to do is find some tools to pinpoint what application process is
triggering the paging.

in other words, i need to find out root cause.

their is a db server that i suspect is causing the issue. but i need to
confirm WHICH process is causing paging.

the O/S has 4gb of physical RAM and never peaks more than 3gb committed. yet
paging is significant during these time periods.

it could be that there's some report tool running that is scanning millions
of records that is causing the O/S to page. i'm not sure.

if i can identify which process(es) are triggering the paging, then i can
begin to dig into those applications to see what's happening within them to
tune.

i have more than enough free RAM on the system that is not being used, so if
i can identify the process, maybe there are ways i can allocate more ram or
adjust it's settings to utilize memory more effectively.

so to summarize:

1. heavy paging for 2.5 hour period every day (consistent)
2. need to identify root process / root cause.

Hi Bob,

Thanks for posting!

I understand that some application is triggering page faults from about
10:00 to 12:30 every day and you need to trace what application is
triggering the page faults. If I have misunderstood your concerns, please
feel free to let me know.

Based on my research, the Windows Task Manager can monitor the page faults.

1. Ctrl+ Alt+ Del -> Click Task Manager

2. Click View tab->Select Columns->Check Page Faults

Then you can view which applications are using the Page Faults.

In addition, I would like to suggest the following steps.

Step 1: Running Spyware software and cleaning the system.
=======================================================

Microsoft Windows Anti-Spyware (Beta)

Spy-killer

Ad-Aware (free version)

SpyBot

Step 2: Try the following on-line free virus scanner.

Hope the information helps. If there is anything that is unclear, please
feel free to let me know.
