Working on network workstations, I found I needed a method to tell when they came online. I wanted a script to email me so I could receive it on my PDA when the connection worked. This way I could be working in the wiring cabinet and hear it successfully connect.
The following script can easily be modified to notify when a server is up or down. I've also added an option to loop the script continuously until specific triggers are met. These triggers can be set at the command line, or hard set into the code for quick deployment. You'll just need to put your email address into the script before you run it.
Requirements: Latest version of BLAT (note the path in line 75).
