[users@httpd] Increasing httpd server load...
Hello All,
I am using redhat 7.2 with apache 1.3.27 running on it. From last few days I
am seeing that server load on my server increases drastically and again
comes down to normal after some time. When I checked the running processes I
found user nobody consuming maximum resources on my server. Is there anyway
to trace out what makes the server load goes up and who is executing that
process?
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
nobody 29545 1.6 0.0 0 0 ? RW 14:03 0:12 [httpd]
nobody 29850 1.9 0.0 0 0 ? RW 14:05 0:12 [httpd]
nobody 29887 2.0 0.0 0 0 ? RW 14:05 0:12 [httpd]

Thank you,

As I said, load average is pretty-much meaningless for a web server. Is
the server responsive to requests? If so, don't worry about it. If not,
then you need to either do some performance tuning or you need to get more
hardware.

This is what my server load goes because of httpd.
load average: 31.78, 23.97, 14.08
Thankx

"nobody" is simply the user that apache is server requests under. Seeing
load spikes is not at all unusual for web servers. In particular, you can
pretty much ignore the "load average" figures. They are not important.
The "cpu usage" is a little more interesting, but what you should focus on
is actual performance.
Are you asking for help identifying exactly which requests are taking up
the processor time? If so, you can see mod_status, or you can add the PID
to your LogFormat and correlate your access_log with your process listing.
