"This section covers notifications in depth and
describes the details of how Nagios can tell other people about
what is happening. We will discuss a simple approach, as well as a
more complex approach on how notifications can make your life
"Probably, most people already know that a plain email
notification about a problem may not always be the right thing to
do. As people's inboxes get cluttered with emails, the usual
approach is to create rules to move certain messages that they
don't even look at to separate folders. There's a pretty good
chance that if people start getting a lot of notifications that
they won't need to react to, 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, they will most probably
not even see the notification email.
"This section talks about the things that can be implemented in
your company to make notifications more convenient to the IT staff.
Limiting the amount of irrelevant information sent to various
people tends to increase their response time, as they will have
much less information to filter out."
