snapshot for web server

MSafty · 01-03-2006, 01:40 PM

i have a web server running fedora core 2 with apache and is running number of websites,
i made #top -c command to check the load average
and i found that the load average rises from 1.05 for the normal average and reaches 4.0 load average instantly but i found that there's any abnormal or strange processes,
so, i want something to take snapshot from the server processes every definite time and make history for it if anybody have an idea.

Code:

#!/bin/bash
mkdir -p processdumps

while [ true ]; do
ps aux > processdumps/$(date +%s)
sleep $1
done

Save that in a file, chmod +x it, and run it like this:

Code:

./snapshotter.sh 10

Where the number is the amount of seconds to wait between snapshots. Hit ^C to stop. The dumps will be at processdumps/

Also check out the "vmstat", "sar" and the "w" commands for troubleshooting. These don't take the specific snapshots you asked for, but may be of some use to you.
