GDNSD-PLUGIN-NULL(8)		     gdnsd		  GDNSD-PLUGIN-NULL(8)

NAME
       gdnsd-plugin-null - gdnsd null plugin

SYNOPSIS
       Example null service_types config:

	 service_types => {
	   my_null_mon => {
	     plugin => null,
	     # ... other generic service_type params
	   }
	 }

       Zonefile	RRs using null resolution

	 foo 300 DYNA null
	 bar 300 DYNC null!whatever

DESCRIPTION
       gdnsd-plugin-null exists	mostly as an example of	the minimum possible
       plugin of both types.  It is simultaneously both	a monitoring plugin
       and a resolution	plugin.

       When used as a resolution plugin	in "DNYA" or "DYNC" RRs, it ignores
       any resource name provided.  It always returns the IPv4 address 0.0.0.0
       and the IPv6 address "::".

       When used as a monitoring plugin	by defining a service_type as shown in
       the example above it emulates the behavior of a real monitoring plugin
       (updating at correct intervals, etc) but	sends a	"DOWN" result at every
       monitoring check	interval without actually checking anything.
