Nagios is a very flexible, open-source, network/host monitoring application. Not only does it do reporting on host uptime and services, it can be configured to send emails and text alerts when a system or service goes down or otherwise changes. I've used this within the corporate realm and it fits well - especially among a heterogeneous network like ours.
Installation
- NOTE: These installation notes were made during the install to Babbage on August 26th, 2009 by Chris Moore.
