+ * Notifications can be handled by the following plugins:
+
+ - notify_desktop
+ Send a desktop notification to a notification daemon, as defined in
+ the Desktop Notification Specification. To actually display the
+ notifications, notification-daemon is required.
+ See http://www.galago-project.org/specs/notification/.
+
+ - notify_email
+ Send an E-mail with the notification message to the configured
+ recipients.
+
+ - exec
+ Execute a program or script to handle the notification.
+ See collectd-exec(5).
+
+ - logfile
+ Writes the notification message to a file or STDOUT/STDERR.
+
+ - network
+ Send the notification to a remote host to handle it somehow.
+
+ - perl
+ Notifications are propagated to plugins written in Perl as well.
+ See collectd-perl(5).
+
+ * Miscellaneous plugins:
+
+ - uuid
+ Sets the hostname to an unique identifier. This is meant for setups
+ where each client may migrate to another physical host, possibly going
+ through one or more name changes in the process.
