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.

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.
