Query - Apache and PHP
Some time when doing Top -d1.... i generally find 2 or 3 httpd process taking a lot CPU
Server is Running PHP, apache, mysql etc.... So my question is, Is there anyway to find which PHP is taking lot CPU that is running behind the Httpd process Here is the Screen Shots top - 13:14:16 up 205 days, 19:01, 1 user, load average: 0.39, 0.32, 0.28 Tasks: 116 total, 1 running, 108 sleeping, 7 stopped, 0 zombie Cpu(s): 9.2%us, 17.0%sy, 0.0%ni, 73.6%id, 0.0%wa, 0.2%hi, 0.0%si, 0.0%st Mem: 7328716k total, 5206584k used, 2122132k free, 431128k buffers Swap: 2031608k total, 92k used, 2031516k free, 3149540k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 22455 ibn 15 0 681m 14m 8604 S 19 0.2 0:07.75 httpd 22169 ibn 15 0 682m 14m 8520 S 1 0.2 0:10.57 httpd 22282 ibn 15 0 681m 14m 8148 S 1 0.2 0:07.06 httpd

Hello,
What I like to do is to use top and sort them by cpu. You can achieve this by invoking top with the -c switch. Code:
[root@radio5 ~]# top -c You will need to setup apache server-status by uncommenting the following lines in httpd.conf. As well as adding ON to a option. A graceful restart is needed on apache. Code:
# ExtendedStatus controls whether Apache will generate "full" status # information (ExtendedStatus On) or just basic information (ExtendedStatus # Off) when the "server-status" handler is called. The default is Off. # ExtendedStatus On Code:
# Allow server status reports, with the URL of http://servername/server-status
# Change the ".your-domain.com" to match your domain to enable.
#
<Location /server-status>
SetHandler server-status
Order deny,allow
Allow from all
# Deny from all
# Allow from .your-domain.com
</Location>
Code:
www.domainame.com/server-status Code:
15-0 4791 0/1967/1967 _ 22.45 7 237 0.0 14.77 14.77 67.72.16.187 www.kyw1060.com GET /pages/1137922.php HTTP/1.0 Also you can use the PID to run a strace on the process. This can help you see what is going on as well. Code:
[root@radio5 ~]# strace -d 1142 Jaysunn Last edited by jaysunn; 7th December 2009 at 08:04 PM.
