Rule-Based Notifier

Project Notes

The included simple Perl script is a rule-based notification addon for Nagios.
Nagios has its own notification logic which decides whether a notification
for an alert should be sent. If this script is defined as the notification
commands, further conditions can be defined by admins to control whether a
notification should be "actually" sent.

By using this script, Nagios admins can decide:

WHO should (or not) be notified,
notification for WHICH hosts/services should (or not) be controlled,
on WHAT states should (or not) be concerned,
at WHEN a notification should (or not) be sent,
HOW to send a notification,
and so on.

All these features are implemented by defining some "rules" which will
be matched by this script while Nagios hand off a notification to it.
Rules are defined in a plain text config file (see inside), no database is
needed.

Changes of v1.1
------------------
* Support partial wildcard in some fields of rules, e.g. "abc*" is a group of all object IDs beginning with "abc"
* Group matching has a priority between exactly matching and wildcard matching (*)
* Admins can supply an extra condition, by matching a Nagios macro with some values, in each rule
* Some bugs fixed
