Monitor system performance

[Vic S. Kelan]

Just wondering if anybody has a script that will monitor and capture to a file that I could use to make a chart my memory, CPU and disk utilization every 1hour? Also If this script can be run by non-root user?
I have glance but of course can only see at a point in time and I am having an unusual spike in memory and disk utilization.
Thanks!!

You will need to modify it slightly to make it work. It is designed to collect the info you desire in the background.

Most of it should work with a non-root user.

Here is a script I use to capture CPU load, Memory Usage and Waiting on IO percentage. I load it into a DB and graph out everything for easy viewing. You will have to change user names and passwords to suit your needs, obviously, but it should work.

Good luck!

If you have glance plus pak, then you can use extract:

55 23 * * 1-5 /opt/perf/bin/extract -xp -r /home/gwild/zgbltemplate -g -b today 7:00 -e today 18:00 -f stdout | /bin/mailx -s 'svr004 performance report' sysadm >/tmp/performance.log 2>&1

Even if this document is for solaris i find it usefull for all UNIX variations some more that others :-).
http://www.adminschoice.com/docs/iostat_vmstat_netstat.htm

It will give some knowhow as to how the standard UNIX performance tools works.

Hi,
I'm using glance in adviser_only mode to registser in a file CPu, disk, memory e swap utilization.
See teh attached script.
It uses this gln_syntax_file:
print "-- ",
gbl_statdate,
" ",
gbl_stattime,
" ",
gbl_cpu_total_util|3|0,
" ",
gbl_disk_util_peak|3|0,
" ",
gbl_mem_util|3|0,
" ",
gbl_swap_space_util|3|0
