GDNSD-PLUGIN-NULL(8) gdnsd GDNSD-PLUGIN-NULL(8)NAMEgdnsd-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
DESCRIPTIONgdnsd-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. With "DYNA" it always returns the IPv4
address 0.0.0.0 and the IPv6 address "::". With "DYNC" it always
returns a CNAME to to the domainname "invalid."
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.
