To the readers that are sysadmins like me that have a Nagios setup to monitor the network, I got a treat for you..
nagg is a Nagios plugin that takes your regular Nagios messages, compresses them into small strings with a special syntax, and shoves as many as it can into as few SMS messages as possible. It also handles redundant messages and contradictory messages intelligently to minimize the message count. For people with limited text-messaging plans, this is a really useful solution. Besides, in this economy, who wants to pay more to AT&T/Verizon/TMobile needlessly?
