[Nagiosplug-help] Monitoring web page change

[Andreas Ericsson]

You need Tripwire, not nagios.


If you still want to do this with nagios, the only thing to do is write 
a plugin that maintains an md5sum library of all the files included in 
the webpage. There is currently no such plugin, and I would stronly 
advice against it due to the load incurred on both the network and the 
CPU of the Nagios server (calculating checksums is a fairly expensive 
business).
