* PHP Probe for PRTG Network Monitor (http://www.paessler.com/prtg)

* With this script you can monitor the diskspace of a php-enabled webserver with PRTG Network Monitor

*                  

*    - Copy the script below into a folder of your web server that is configured to run PHP scripts (e.g. /yourpath)

*    - Edit the $username and $password constants below to your liking

*    - Test the script by calling it in a web browser, e.g. 

*

*        http://yourserver/yourpath/prtgphpprobe.php?drive=C:&user=myuser&pass=mypass

*

*    - In the URL, replace the "drive" value C: with the according value: 

*

*        Windows server    The drive letter you want to monitor, followed by a colon

*        Linux server    The path you want to monitor, for example / for root

*

*    - In the URL, replace myuser and mypass by the values you entered in the script.

*    - As soon as the script returns the desired values, you can add it as a HTTP Content sensor in PRTG. 

*

*     - See /en/topic/1023 for more details.
