AWStats MultiteSite Summary

What is and does AWStats MultiSite Summary exactly? Unlike other AWStats addons this little tool summarizes multiple sites in a clear and compact way on a per month and a per user basis.

It depends on the following AWStats settings for each site:

AllowAccessFromWebToFollowingAuthenticatedUsers="user1 user2 user3"

and a seperate Apache VirtualHost (might work as subdirectory installation too) to act as centralized AWStats "portal" (see "Apache Configuration" below).

To see a working online demo please go to and login as awstats-mss-demo with password demo.


AWStats MultiSite Summary has been tested with Perl 5.8.x and will most likely work with all Perl5 versions.

Besides AWStats itself the following Perl modules are required and have to be installed. You can find them all on CPAN (

  • CGI
  • File::Find::Rule
  • File::Slurp
  • Math::Round::Var
  • Template Toolkit


To install AWStats MultiSite Summary:

cd /path/to/DocumentRoot
tar xvf AWStats-MultiSite-Summary-1.8.tar.gz
mv AWStats-MultiSite-Summary-1.8/* .

Additionally AWStats' has to be copied to /path/to/DocumentRoot so AWStats MultiSite Summary can link to it from its summary page. Creating a symlink might works too - depending on your Apache/VirtualHost configuration. For people experienced with Apache configuration there are of course other ways to do this.

Configuring AWStats MultiSite Summary

Edit and change the following values to suit your needs. Default values are:

my $awstats_config_dir = '/etc/awstats';
my $awstats_uri        = '/';
my $template_root      = '_system/templates';

NOTE: AWStats MultiSite Summary (= the user your Apache is running as) needs read access to both the directory containinig AWStats configuration files and AWStat's CacheDir.

Configuring AWStats

Besides a seperate AWStats configuration file for each site to be analyzed it is strongly adviced to use the schema awstats.conf, awstats.conf.local and awstats.sitename.conf.

This way you can override package/awstats defaults with system-specific values and site-specific values.

  1. awstats.sitename.conf: Include awstats.conf at the beginning
  2. awstats.conf: Include awstats.conf.local at the end
  3. awstats.conf.local

As mentioned above for each site these parameters have to be set:

AllowAccessFromWebToFollowingAuthenticatedUsers="user1 user2 user3"

You can set AllowAccessFromWebToAuthenticatedUsersOnly in awstats.conf.local for all sites and AllowAccessFromWebToFollowingAuthenticatedUsers for each site's awstats.sitename.conf

Users defined here must be able to login on your AWStats "portal" (see Configuring Apache below) via HTTP 401 Authentication and will then get an overview of all sites analysis they are allowed to access.

This way you can also define a user who is allowed to access all available AWStats sites.

If the authenticated user has access to only one AWStats site, he will be redirected to the correspondig stats. Only if the user is permitted to view multiple sites, a summary page with links to each one will be genareted.

Configuring Apache

It is strongly advised that you create a seperate Apache VirtualHost as centralized AWStats "portal" like e.g.

Furthermore you need to enable HTTP Authentication (Basic or Digest) for AWStats MultiSite Summary to work. You can do this either for the whole VirtualHost or just a Location or Directory directive. The users you add to your UserFile (.htaccess, mod_auth_ldap, ...) have to be identical with the ones you define in the respective sites' AWStats configuration file (see AllowAccessFromWebToFollowingAuthenticatedUsers). You can also use other types of Apache authentication mechanisms (e.g. LDAP), as long as it's an 401 authentication and the environment variable REMOTE_USER is available for AWStats MultiSite Summary.

AWStats MultiSite Summary as well as AWStats itself are written in Perl so you will also have to enable CGI support for the DocumentRoot (see example VirtualHost).

An example Apache VirtualHost would look like:


  DocumentRoot /path/to/DocumentRoot

  ErrorLog /var/log/httpd/stats_yoursite.error_log
  CustomLog /var/log/httpd/stats_yoursite.access_log combined

  <Directory /path/to/DocumentRoot>
    AuthName "HTTP Statistics"
    AuthType Basic
    AuthUserFile /etc/httpd/auth/
    require valid-user

    Options +ExecCGI
    AddHandler cgi-script .pl

For information about how to create and maintain the AuthUserFile please see the Apache documentation at

How it works

AWStats MultiSite Summary matches the authenticated user (HTTP 401 Authentication) with available site configuration files in e.g. /etc/awstats. If a match occures it opens the file, reads some configuration values and tries to open the latest corresponding AWStats cache file in "CacheDir" (e.g. /var/lib/awstats/ for displaying the summary.

If no cache file can be found (e.g. AWStats hasn't analyzed a site yet) the site will not be visibile in the summary.


To ease up installation AWStats MultiSite Summary is also avaiable as a Docker image. Please see for details.
