Re: Per virtualhost bandwidth/hitrate statistics for Apache

Hi,

Thanks. But this is to limit bandwidth. I didn't want that. I just want
to measure how much bandwidth is used (and other things), per virtual
host, in real time.

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.

I just wonder if anyone has any good hints about software to use (Apache

What do people use to measure statistics per virtualhost?

I use Apache's logrotate and a separate log directory for each
virtualhost. I
have a script that runs from cron every day that runs the logs through
webalizer and then cleans up logs older than a specified number of days. In
fact (since I'm feeling like sharing), here it is:

#!/bin/sh
for path in `cat /usr/local/scripts/logpaths.txt` ; do
for log in `find ${path} -name access\* | sort -n` ; do
if [ -r ${path}/hostname.txt ]; then
host=`cat ${path}/hostname.txt`
/usr/local/bin/webalizer -Q -p -n ${host} \
-o ${path} ${log}
else
/usr/local/bin/webalizer -Q -p -o ${path} ${log}
fi
done
find ${path} -name \*.log\* ! -newermt '1 month ago' -delete
done

The script depends on the existence of a "logpaths.txt" file, which
contains a
list of directories to scan, one per line. It also supports an
optional "hostname.txt" for each directory so webalizer can use the right
one
in the title of its reports. Webalizer output is stored in the log
directory
but that could easily be changed.

The output is plain HTML, so you can publish it on a (presumably private)
webserver somewhere. Since I give certain clients access to their reports I
use webmin for this. However I just point webmin to a dummy file within
each
log directory and don't let it actually run webalizer (since my script
already takes care of that). So just the "View report" button works, but it
gets the job done.
