Nagios offers several ways to let people know that something is wrong. Notifications can range from simple emails to a complex system that deals with multiple ways to communicate problems, as well as the ability to choose the appropriate way dynamically. This will help eliminate people from having to deal with their emails, and will help in resolving issues much more effectively.

Nagios can deliver information about problems in almost any way you can possibly imagine. Notifications can be sent as emails, instant messages, and Windows messaging texts. You can also have a text message over GSM networks; whatever works best for you and your colleagues. You can even set up VoIP combined with speech synthesis to let people know what the problems are.

Nagios also has a very powerful mechanism for escalating problems. When set up correctly, this is a very useful tool which will aid in complex problem resolution. In the case of larger problems, it can also be used to communicate problems properly...
