Pandora FMS is an open source application that can be used to monitor anything online like:

• if a website is up or down
• if the content of a website is changed (deface control or when value of a stock changes..)
• diskspace or CPU usage of a remote server (via SNMP or TCP/IP)
• & many more..

Pandora FMS can run on any operating system, with specific agents for each platform, getting the data and sending it to a server.

You can get real-time reports for every monitor & have them sent to an e-mail adrdess.

It can also send notifications of events via e-mail, SMS or Jabber (MSN, GTalk..) to the desired users.

P.S. To mention, Pandora FMS is not a simple script to install. It is made up by several shellscript files (UNIX/Linux Agents), a Web application in PHP (Console), some code in C++ (Windows Agent), some code in PERL5 (Server) and some structure and data in SQL (Database).
