apache

check Apache server version by creating a simple e.g. serverinfo.php file with following statement: <?php phpinfo(); ?>

and open in your browser: http://your host/serverinfo.php. Find the version info in the Apache Version section:

Apache Version – Apache/2.0.53 (Linux/SUSE)

or run from the command line:

/usr/sbin # apache2ctl -v

Server version: Apache/2.0.53

Server built: Aug 30 2006 13:14:23

h969344:/usr/sbin #

Next add mod_status to your APACHE_MODULES by editing /etc/sysconfig/apache2 configuration – the Status module allows a server administrator to find out how well a server is performing. A HTML page is presented that gives the current server statistics in an easily readable form:

APACHE_MODULES=

“access actions alias auth auth_dbm autoindex cgi

dir env expires headers include log_config mime

mod_status negotiation setenvif

ssl suexec userdir php4 rewrite”

In the same file and if extended logging is needed, set APACHE_EXTENDED_STATUS=”on” – be careful here, this will degrade performance.

Edit httpd.conf and add a Location section to your virtualhost section (remove Include /etc/apache2/mod_status.conf):

<VirtualHost *:80>

….

<Location /server-status>

SetHandler server-status

# Order deny,allow

# Deny from all

Allow from .yourdomain

</Location>

….

</VirtualHost>

restart the HTTP server: /usr/sbin/rcapache2 restart

You should see your Apache server status now by issuing this URL: http://yourHost/server-status providing the following information:

• The number of worker serving requests
• The number of idle worker
• The status of each worker, the number of requests that worker has performed and the total number of bytes served by the worker (*)
• A total number of accesses and byte count served (*)
• The time the server was started/restarted and the time it has been running for
• Averages giving the number of requests per second, the number of bytes served per second and the average number of bytes per request (*)
• The current percentage CPU used by each worker and in total by Apache (*)
• The current hosts and requests being processed (*)

The lines marked “(*)” are only available if ExtendedStatus is On

awstats

To display HTTP server log information in a graphical form, install awstats:

AWStats is a free powerful and featureful tool that generates advanced web, streaming, ftp or mail server statistics, graphically.

Copy awstats to a directory of your choice, installation defaults to /usr/local/awstats. Then run the awstats configuration process: perl awstats_configure.pl, which will add directives to your httpd.conf and create a configuration file (default location: /etc/awstats)

<Directory “/usr/local/awstats/wwwroot”>

Options all

AllowOverride None

Order allow,deny

Allow from all

</Directory>

Alias /awstatsclasses “/usr/local/awstats/wwwroot/classes/”

Alias /awstatscss “/usr/local/awstats/wwwroot/css/”

Alias /awstatsicons “/usr/local/awstats/wwwroot/icon/”

ScriptAlias /awstats/ “/usr/local/awstats/wwwroot/cgi-bin/”

[SinglePic not found]

Once done run the data import process from the cgi-bin folder of your awstats installation (you can automate this in the config file): perl awstats.pl config=yourdomain. See results of your site: http://yourdomain/awstats/awstats.pl or at this demo site
