Process information?

Process information?

am 09.12.2003 02:37:32 von Neo Wee Teck

Hi,

I saw some difference in the process info when using RedHat kernel 2.4.20-8 and the kernel from kernel.org (2.4.23)

With Redhat's kernel, process show something like this

www 10186 0.0 0.1 2536 1272 ? S Dec08 0:01 [httpd]
www 10187 0.0 0.1 2536 1272 ? S Dec08 0:01 [httpd]
www 10188 0.0 0.1 2536 1276 ? S Dec08 0:01 [httpd]

But with 2.4.23 kernel it shows

www 5673 0.0 0.1 2536 1272 ? S Dec08 0:01 /usr/local/apache/bin/httpd
www 5674 0.0 0.1 2536 1272 ? S Dec08 0:01 /usr/local/apache/bin/httpd
www 5675 0.0 0.1 2536 1276 ? S Dec08 0:01 /usr/local/apache/bin/httpd

Any configuration in the kernel that i missed out? I prefer the way processes are shown in Redhat's kernel but would like to use the 2.4.23's kernel.

Cheers

Neo

try adding c to whatever ps options you use.

[whit@giftie whit]$ ps -C xfstt u
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 510 0.0 0.9 1896 740 ? S Dec02 0:00 /usr/X11R6/bin/xf

[whit@giftie whit]$ ps -C xfstt uc
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

[whit@giftie whit]$ tty

[whit@giftie whit]$ cat /dev/vcc/4|fold|trail >oops

This is nothing to do with the kernel patch level, I think.

But in redhat's kernel, even with ps ax, it shows [httpd]

From man ps:

Programs swapped out to disk will be shown without command
line arguments, and unless the c option is given, in
brackets.

Anything about the RedHat kernel that would cause httpd's to be swapped
out? Of course, if they are inactive, they will get swapped out
eventually.

OH Thanks for the information!

Now I clearly understand :)


But it is wierd for redhat to swap "almost" every process into disk. Doesn't matter, i'm not using also ;)

Thanks again
