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.
