If you would like your server to be monitored by , you will need to download a copy of the data gathering client script (rrd-client.pl). Click here to download a copy of rrd-client.pl. rrd-client.pl currently works best on Linux 2.6 installs or higher, but will does have limited support for Linux 2.4 distributions, BSD, Darwin and Solaris. Cross platform support will improve over time. To get the best results by monitoring as much as possible, you should make sure that you have the following programs installed:

/usr/bin/iostat - Required to monitor hard disk IO
/usr/bin/vmstat - Required to monitor CPU utilisation
/usr/bin/sensors - Required to monitor CPU temperature
/usr/bin/hddtemp - Required to monitor hard disk temperature

Tree-hugging debian users can install these using the following command:

sudo apt-get install sysstat hddtemp lm-sensors procps

Once you have downloaded rrd-client.pl and tested that it generates output, you should add it to your crontab to HTTP POST the data to our server run every 4 or 5 minutes. A typical crontab entry might be:

*/4If you are not using a Vixie complaint
      cron daemon, or which to offset execution another minute, you may wish to
      use the following instead:
1,6,11,16,21,26,31,36,41,46,51,56
      * * * * sleep 10;By delaying the execution
      of your rrd-client.pl script until 10 seconds after the minute, you will help
      avoid taking misrepresentative elevated data samples due to spawning
      cran tasks that happen on the minute. /usr/local/bin/rrd-client.pl
       -p http:///cgi-bin/rrd-server.cgi >/dev/null
