	timeout	= 1.5
	tos = 0x20
	usestdout = true

	# [...]

	*** Targets ***

	# [...]

	+ mytarget
	# probe	= FPing	# if the default probe is something else
	host = my.host

DESCRIPTION
       Integrates FPing	as a probe into	smokeping. The variable	binary must
       point to	your copy of the FPing program.	 If it is not installed	on
       your system yet,	you can	get a slightly enhanced	version	from "pub" in
       www.smokeping.org.

       The (optional) packetsize option	lets you configure the packetsize for
       the pings sent.

       Since version 3.3 fping sends its statistics to stdout. Set usestdout
       to 'true' so make smokeping read	stdout instead of stderr.

       In blazemode, FPing sends one more ping than requested, and discards
       the first RTT value returned as it's likely to be an outlier.

       The FPing manpage has the following to say on this topic:

       Number of bytes of ping data to send.  The minimum size (normally 12)
       allows room for the data	that fping needs to do its work	(sequence
       number, timestamp).  The	reported received data size includes the IP
       header (normally	20 bytes) and ICMP header (8 bytes), so	the minimum
       total size is 40	bytes.	Default	is 56, as in ping. Maximum is the
       theoretical maximum IP datagram size (64K), though most systems limit
       this to a smaller, system-dependent number.

VARIABLES
       Supported probe-specific	variables:

       binary
	   The location	of your	fping binary.

	   Example value: /usr/bin/fping

	   This	setting	is mandatory.

       blazemode
	   Send	an extra ping and then discarge	the first answer since the
	   first is bound to be	an outliner.

	   Example value: true

       hostinterval
	   The fping "-p" parameter, but in (possibly fractional) seconds
	   rather than milliseconds, for consistency with other	Smokeping
	   probes. From	fping(1):

	   This	parameter sets the time	that fping  waits between successive
	   packets to an individual target.

	   Example value: 1.5

       mininterval
	   The fping "-i" parameter, but in (probably fractional) seconds
	   rather than milliseconds, for consistency with other	Smokeping
	   probes. From	fping(1):

	   The minimum amount of time between sending a	ping packet to any
	   target.

	   Example value: 0.001

	   Default value: 0.01

       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%

       packetsize
	   The ping packet size	(in the	range of 12-64000 bytes).

	   Example value: 5000

       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: 20

       sourceaddress
	   The fping "-S" parameter . From fping(1):

	   Set source address.

	   Example value: 192.168.0.1

       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
	   The fping "-t" parameter, but in (possibly fractional) seconds
	   rather than milliseconds, for consistency with other	Smokeping
	   probes. Note	that as	Smokeping uses the fping 'counting' mode (-C),
	   this	apparently only	affects	the last ping.

	   Example value: 1.5

       tos Set the type	of service (TOS) of outgoing ICMP packets.  You	need
	   at laeast fping-2.4b2_to3-ipv6 for this to work. Find a copy	on
	   www.smokeping.org/pub.

	   Example value: 0x20

       usestdout
	   Listen for FPing output on stdout instead of	stderr ... (version
	   3.3+	sends its statistics on	stdout).

	   Example value: true
