NAME

	*** Probes ***

	+DNS

	binary = /usr/bin/dig #	mandatory
	forks =	5
	offset = 50%
	step = 300
	timeout	= 15

	# The following	variables can be overridden in each target section
	lookup = www.example.org
	pings =	5
	server = ns1.someisp.net

	# [...]

	*** Targets ***

	probe =	DNS # if this should be	the default probe

	# [...]

	+ mytarget
	# probe	= DNS #	if the default probe is	something else
	host = my.host
	lookup = www.example.org
	pings =	5
	server = ns1.someisp.net

DESCRIPTION
       Integrates dig as a probe into smokeping. The variable binary must
       point to	your copy of the dig program. If it is not installed on	your
       system yet, you should install bind-utils >= 9.0.0.

       The Probe asks the given	host n-times for it's name. Where n is the
       amount specified	in the config File.

VARIABLES
       Supported probe-specific	variables:

       binary
	   The location	of your	dig binary.

	   Example value: /usr/bin/dig

	   This	setting	is mandatory.

       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

       timeout
	   How long a single 'ping' takes at maximum

	   Example value: 15

	   Default value: 5

       Supported target-specific variables:

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

	   Example value: www.example.org

       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

       server
	   Name	of the dns server to use.

	   Example value: ns1.someisp.net
