This section covers notifications in more depth and details how Nagios can tell other people about what is happening. We will discuss a simple approach, as well as a more complex one on how notifications can make your life easier.
In many cases, a plain e-mail notification about a problem may not always be the right thing to do. As people's inboxes get cluttered with e-mails, the usual approach is to create rules to move certain messages that they don't even read to separate folders. There's a pretty good chance that if people start getting a lot of notifications to which they won't need to react, they'll simply ask their favorite mailing program to move these messages into a do not look in here unless you have plenty of time folder. Moreover, in such cases, if there is an issue they should be handling at the time, they will most probably miss the notification e-mail.
