Server Stats
From OpenSimulator
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', 'lowerLimit' => 0, 'altAutoscaleMax' => true, 'content' => array( array( 'type' => 'AREA', 'source' => 'opensim', 'ds' => 'opensim_cpu_sys', 'cf' => 'AVERAGE', 'legend' => 'OpenSim Sys CPU%', 'color' => 'FF0000', ), array( 'type' => 'AREA', 'source' => 'opensim', 'ds' => 'opensim_cpu_user', 'cf' => 'AVERAGE', 'legend' => 'OpenSim User CPU%', 'color' => '00FF00', 'stacked' => true, ), ) ); $config['list'][] = array( 'title' => 'OpenSim Threads', 'lowerLimit' => 0, 'altAutoscaleMax' => true, 'content' => array( array( 'type' => 'AREA', 'source' => 'opensim', 'ds' => 'opensim_threads', 'cf' => 'AVERAGE', 'legend' => 'number of opensim threads', 'color' => '0000BB', ), ) ); $config['list'][] = array( 'title' => 'OpenSim Memory', 'lowerLimit' => 0, 'altAutoscaleMax' => true, 'content' => array( array( 'type' => 'AREA', 'source' => 'opensim', 'ds' => 'opensim_virt', 'cf' => 'AVERAGE', 'legend' => 'OpenSim Memory (Virt)', 'color' => '00BB00' ), array( 'type' => 'AREA', 'source' => 'opensim', 'ds' => 'opensim_real', 'cf' => 'AVERAGE', 'legend' => 'OpenSim Memory (Real)', 'color' => 'BB0000' ), ) );
- 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.
