I have a RHEL 5.4 server which runs an Apache web server(2.2.23 compiled with prefork MPM).I want to find out the memory utilised by the web server.
Code:
# ps -ylC httpd | wc -l
245
# ps -ylC httpd | more
S UID PID PPID C PRI NI RSS SZ WCHAN TTY TIME CMD
S 48 376 1074 0 75 0 4640 45817 - ? 00:00:00 httpd
My understanding is that RSS is the amount of real memory used by a process.So am adding the RSS column to arrive at total memory used by all httpd processes.
So the total memory used by my web server is 1190456Kb or 1.19GB. But from "free -m" command i am getting around 1gb cached and 1.6gb used while as the total RAM is just 2GB.
Can someone point where i am wrong? Is this the right way to calculate memory utilised by a webserver?
Any other better methods?
Thanks

Forgot to add this:
Output of top:
Code:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
376 apache 15 0 178m 4784 2076 S 0.0 0.2 0:00.11 httpd
378 apache 15 0 178m 5436 2160 S 0.0 0.3 0:00.13 httpd
426 apache 15 0 178m 5448 2136 S 0.0 0.3 0:00.11 httpd
The top command shows something like VIRT using 178m. The documentation says VIRT = RES + Swap
SO each "httpd" process is using 178mb?? swap usage shows zero(as can be seen in "free -m) command.
Hi,
Is there any way in Unix to check for the system usage processwise ??

bup-web
bup-ftp(1) General Commands Manual bup-ftp(1)NAME
bup-web - Start web server to browse bup repositiory
SYNOPSIS
bup web [[hostname]:port]
DESCRIPTION
bup web starts a web server that can browse bup repositories. The file hierarchy is the same as that shown by bup-fuse(1), bup-ls(1) and
bup-ftp(1).
hostname and port default to 127.0.0.1 and 8080, respectively, and hence bup web will only offer up the web server to locally running
clients. If you'd like to expose the web server to anyone on your network (dangerous!) you can omit the bind address to bind to all avail-
able interfaces: :8080.
EXAMPLE
$ bup web
Serving HTTP on 127.0.0.1:8080...
^C
$ bup web :8080
Serving HTTP on 0.0.0.0:8080...
^C
