HSLAB HTTP Monitor Online Help

How it works?

HSLAB HTTP Monitor uses options of Apache web server to display its connection statistics.

The statistical information is obtained from the server using HTTP requests and processed by the program for visualization.

Connection statistics:

·	Server connections diagram;

·	Server connections tree with all virtual servers on this host;

·	All opened documents / files for each virtual host;

·	Unlimited number of server profiles.

·	Server version and operation system type;

·	Time when the server was last restarted;

·	Server uptime;

·	Number of requests for this time and full traffic;

·	Number of requests per second, volume of information per second and average volume of a request;

·	System processor performance counters.

Before using the program, you should enable your web server to respond to queries about connection statistics.

ATTENTION! If you are unfamiliar with the configuration of Apache web servers, ask your system administrator to help you.

For Apache versions 1.3.x - 2.0.x:

LoadModule status_module modules/mod_status.so

This line can differ a little depending on the version of your server and operation system. If this line has ahead a symbol # that remove it.

Now need to proceed to a configuration of the status. Find the lines:

# 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

Also remove a symbol # in line #ExtendedStatus On. In result this section should look like:

# 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

Further we should to install the status handler. Find the lines:

# Change the ".yourdomain.com" to match your domain to enable.

#<Location/server-status>

# SetHandler server-status

# Order deny, allow

# Deny from all

# Allow from .yourdomain.com

#</Location>

Also remove superfluous symbols #. Now the section should look so:

# Allow server status reports, with the URL of http://servername/server-status

# Change the ".yourdomain.com" to match your domain to enable.

SetHandler server-status

Order deny, allow

Deny from all

Allow from .yourdomain.com

</Location>

Allow from .yourdomain.com" enables queries of the status from any computer of your domain(yourdomain.com). If you want to limit access only for the your computer, you should write "Allow from yourcomputer.yourdomain.com". Where your computer is a name of your computer and yourdomain - a name of your domain. Also you can write "Allow from all". In this case, the statistics of your wed server will be accessible from any computer in the Internet. We urgently do not recommend so to do, you should have very serious reason for this purpose!

For Apache versions 2.2.x:

First of all, you should be convinced, that your server uses the mod_status module. For this purpose open in your text editor a web server configuration file httpd.conf. Find the section loading modules and check up, whether there is there a line:

LoadModule status_module modules/mod_status.so

This line can differ a little depending on the version of your server and operation system. If this line has ahead a symbol # that remove it.

Now you should locate lines:

# Real-time info on requests and configuration

#Include conf/extra/httpd-info.conf

and uncomment second line:

# Real-time info on requests and configuration

Include conf/extra/httpd-info.conf

Now need to proceed to a configuration of the status. Open conf/extra/httpd-info.conf file and find the lines:

#ExtendedStatus On

ExtendedStatus On

SetHandler server-status

Order deny,allow

Deny from all

Allow from .yourdomain.com

</Location>

Or for testing:

SetHandler server-status

Deny from all

Allow from all

</Location>

Line "Allow from .yourdomain.com" enables queries of the status from any computer of your domain(yourdomain.com). If you want to limit access only for the your computer, you should write "Allow from yourcomputer.yourdomain.com". Where your computer is a name of your computer and yourdomain - a name of your domain. Also you can write "Allow from all". In this case, the statistics of your wed server will be accessible from any computer in the Internet. We urgently do not recommend so to do, you should have very serious reason for this purpose!

Your web server configuration is finished! Now you should save your changes and restart your web the server.
