DESCRIPTION
       Like DNS, but uses Net::DNS and Time::HiRes instead of dig. This	probe
       does *not* retry	the request three times	before it is considerd "lost",
       like dig	and other resolver do by default. If operating as caching
       Nameserver, BIND	(and maybe others) expect clients to retry the request
       if the answer is	not in the cache. So, ask the nameserver for something
       that he is authoritative	for if you want	measure	the network packet
       loss correctly.

       If you have a really fast network and nameserver, you will notice that
       this probe reports the query time in microsecond	resolution. :-)

VARIABLES
       Supported probe-specific	variables:

       forks
	   Run this many concurrent processes at maximum

	   Example value: 5

	   Default value: 5

       offset
	   If you run many probes concurrently you may want to prevent them
	   from	hitting	your network all at the	same time. Using the probe-
	   specific offset parameter you can change the	point in time when
	   each	probe will be run. Offset is specified in % of total interval,
	   or alternatively as 'random', and the offset	from the 'General'
	   section is used if nothing is specified here. Note that this	does
	   NOT influence the rrds itself, it is	just a matter of when data
	   acqusition is initiated.  (This variable is only applicable if the
	   variable 'concurrentprobes' is set in the 'General' section.)

	   Example value: 50%

       step
	   Duration of the base	interval that this probe should	use, if
	   different from the one specified in the 'Database' section. Note
	   that	the step in the	RRD files is fixed when	they are originally
	   generated, and if you change	the step parameter afterwards, you'll
	   have	to delete the old RRD files or somehow convert them. (This
	   variable is only applicable if the variable 'concurrentprobes' is
	   set in the 'General'	section.)

	   Example value: 300

       Supported target-specific variables:

       ipversion
	   The IP protocol used. Possible values are "4" and "6".  Passed to
	   echoping(1) as the "-4" or "-6" options.

	   Example value: 4

       lookup
	   Name	of the host to look up in the dns.

	   Example value: www.example.org

       mininterval
	   Minimum time	between	sending	two lookup queries in (possibly
	   fractional) seconds.

	   Default value: 0.5

       pings
	   How many pings should be sent to each target, if different from the
	   global value	specified in the Database section. Note	that the
	   number of pings in the RRD files is fixed when they are originally
	   generated, and if you change	this parameter afterwards, you'll have
	   to delete the old RRD files or somehow convert them.

	   Example value: 5

       port
	   The UDP Port	to use.

	   Default value: 53

       protocol
	   The Network Protocol	to use.

	   Default value: udp

       recordtype
	   Record type to look up.

	   Default value: A

       require_answers
	   Only	Count Answers with answer count	>= this	value.

	   Default value: 0

       require_noerror
	   Only	Count Answers with Response Status NOERROR.

	   Default value: 0

       timeout
	   Timeout for a single	request	in seconds.

	   Default value: 5
