Mode of operation. This option controls the manner in which the gatherer operates. The modes currently supported are "once" (the default, best used manually or via cron) which runs all tests once then exits, and "wait" (best used when daemonized) which will run all tests, wait for the gatherer interval to expire, and then repeat.
Types of notifications that can be tied to events.
Name - Descriptive name of the notification
