Per virtualhost bandwidth/hitrate statistics for Apache

[Jorge Evangelista]

Hi Anders,

A days ago I have configured a web server with bandwidth manager
(module bwmod) compile with apache web server. It works fine. You
could try install  this module http://bwmod.sourceforge.net/index.html
and test with your virtualhosts.

Here,  my small guide install, it made in spanish.

Instalando el bwmod, primero comentar las lineas mencionadas abajo

vi mod_bw.c

/* Compatibility for APR < 1 */
#if (APR_MAJOR_VERSION >= 1)
    #define apr_atomic_inc32 apr_atomic_inc
    #define apr_atomic_dec32 apr_atomic_dec
    #define apr_atomic_add32 apr_atomic_add
    #define apr_atomic_cas32 apr_atomic_cas
    #define apr_atomic_set32 apr_atomic_set
#endif


Compilar con el siguiente comando

/usr/local/apache2/bin/apxs  -i -a -c mod_bw.c


Habilitar en apache   httpd.conf

BandWidthModule On


Para bandwitdh ilimitado a una IP
BandWidth 200.168.190.6  0


Para colocar  el bandwidth a los virtual hosts

Limit al internal users to 1000 kb/s with a minimum of 50kb/s

    <Virtualhost *>
      BandwidthModule On
      ForceBandWidthModule On
      Bandwidth all 1024000
      MinBandwidth all 50000
      LargeFileLimit * 500 50000
      Servername www.example.com
    </Virtualhost>

    Limit every user to a max of 10Kb/s on a vhost :

    <Virtualhost *>
      BandwidthModule On
      ForceBandWidthModule On
      Bandwidth all 10240
      MinBandwidth all -1
      Servername www.example.com
    </Virtualhost>


   Examples :
              BandWidth    all 102400
              MinBandWidth all 50000

             The example above, will have a top speed of 100kb for the 1º
            client. If more clients come, it will be splitted accordingly but
            everyone will have at least 50kb (even if you have 50 clients)

              BandWidth    all 50000
              MinBandWidth all -1

             This example, makes everyone have 50kb as top speed.
