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 ??

GIT-INSTAWEB(1) Git Manual GIT-INSTAWEB(1)NAME
git-instaweb - Instantly browse your working repository in gitweb
SYNOPSIS
git instaweb [--local] [--httpd=<httpd>] [--port=<port>]
[--browser=<browser>]
git instaweb [--start] [--stop] [--restart]
DESCRIPTION
A simple script to set up gitweb and a web server for browsing the local repository.
OPTIONS -l, --local
Only bind the web server to the local IP (127.0.0.1).
-d, --httpd
The HTTP daemon command-line that will be executed. Command-line options may be specified here, and the configuration file will be
added at the end of the command-line. Currently apache2, lighttpd, mongoose, plackup and webrick are supported. (Default: lighttpd)
-m, --module-path
The module path (only needed if httpd is Apache). (Default: /usr/lib/apache2/modules)
-p, --port
The port number to bind the httpd to. (Default: 1234)
-b, --browser
The web browser that should be used to view the gitweb page. This will be passed to the git web--browse helper script along with the
URL of the gitweb instance. See git-web--browse(1) for more information about this. If the script fails, the URL will be printed to
stdout.
start, --start
Start the httpd instance and exit. Regenerate configuration files as necessary for spawning a new instance.
stop, --stop
Stop the httpd instance and exit. This does not generate any of the configuration files for spawning a new instance, nor does it close
the browser.
restart, --restart
Restart the httpd instance and exit. Regenerate configuration files as necessary for spawning a new instance.
CONFIGURATION
You may specify configuration in your .git/config
[instaweb]
local = true
httpd = apache2 -f
port = 4321
browser = konqueror
modulepath = /usr/lib/apache2/modules
If the configuration variable instaweb.browser is not set, web.browser will be used instead if it is defined. See git-web--browse(1) for
more information about this.
