+Submits a notification to the daemon which will then dispatch it to all plugins

+The B<PUTNOTIF> if followed by a list of options which further describe the

+mandatory.

+Valid options are:

+=item B<message=>I<Message> (B<REQUIRED>)
+
+Sets the message of the notification. This is the message that will be made
+accessible to the user, so it should contain some useful information. This
+option must be the last option because the rest of the line will be its value,
+even if there are spaces and equal-signs following it! This option is
+mandatory.

+=item B<severity=failure>|B<warning>|B<okay> (B<REQUIRED>)
+
+Sets the severity of the notification. This option is mandatory.

+=item B<time=>I<Time> (B<REQUIRED>)

+Sets the time of the notification. The time is given as "epoch", i.E<nbsp>e. as
+seconds since January 1st, 1970, 00:00:00. This option is mandatory.

+These "associative" options establish a relation between this notification and
+collected performance data. This connection is purely informal, i.E<nbsp>e. the
+daemon itself doesn't do anything with this information. However, websites or
+GUIs may use this information to place notifications near the affected graph or
+table. All the options are optional, but B<plugin_instance> without B<plugin>
+or B<type_instance> without B<type> doesn't make much sense and should be
