==Installation steps==

 +
* Get Serverstats from [http://download.berlios.de/serverstats/serverstats-0.8.2.tar.bz2 Berlios]
 +
* Install rddtool (depending on your distro, it should be in the repository. Otherwise download [http://oss.oetiker.ch/rrdtool/ here])
 +

 +
<source lang="bash">
 +
svn checkout http://forge.opensimulator.org/svn/serverstats

</source>
 +
* Copy serverstats to /my/apache/root/serverstats
 +
* Move ./serverstats/config.sample/ to ./serverstats/config/
 +
* Copy the opensim.php module to ./serverstats/config

Check out the CPU-load

Installation steps

  • Get Serverstats from Berlios
  • Install rddtool (depending on your distro, it should be in the repository. Otherwise download here)
  • Get the OpenSim serverstats module: 
svn checkout http://forge.opensimulator.org/svn/serverstats
  • Copy serverstats to /my/apache/root/serverstats
  • Move ./serverstats/config.sample/ to ./serverstats/config/
  • Copy the opensim.php module to ./serverstats/config
  • Edit ./serverstats/config/sources.php, and add this code: 
include "opensim.php";
$config['opensim']['module'] = new opensim();
  • Edit ./serverstats/config/graph.php, and add this code: 
$config['list'][] = array(
        'title' => 'OpenSim CPU',

  • Make sure you allow php to access /proc . Edit php.ini and set open_basedir = ..:/proc
  • Add a crontab with 'crontab -e', and enter a cronjob for update.php: 
* * * * * php /my/apache/root/serverstats/update.php
  • Check out if the script executes the way it's supposed to be, by running it from the shell. 
php update.php

Done! Now check out if the graphs are generated, by pointing your browser to the serverstats directory. You'll see some nice stats if everything went right.
