Try the mon utility scripts from kernel.org:

Alerts that come with mon:

    * Email notification.
    * Alphanumeric paging notification via modem, using QuickPage.
    * Alphanumeric messaging to portable devices using SNPP.
    * Alphanumeric paging via email.
    * Traps can be delivered to remote mon servers.
    * It is trivial to add your own alert, and it does not require  
      changing any code in the server. 

An example script of what mon can do:

Here's the main mon page:
