NAME
       Smokeping::probes::EchoPingDiscard - an echoping(1) probe for SmokePing

OVERVIEW
       Measures	TCP or UDP discard (port 9) roundtrip times for	SmokePing.

SYNOPSIS
	*** Probes ***

	+EchoPingDiscard

	binary = /usr/bin/echoping
	forks =	5
	offset = 50%
	step = 300

	# The following	variables can be overridden in each target section
	extraopts = -some-letter-the-author-did-not-think-of
	fill = A
	ipversion = 4
	pings =	5
	priority = 6
	size = 510
	timeout	= 1
	tos = 0xa0
	udp = no
	waittime = 1

	# [...]

	*** Targets ***

	probe =	EchoPingDiscard	# if this should be the	default	probe

	# [...]

	+ mytarget
	# probe	= EchoPingDiscard # if the default probe is something else
	host = my.host
	extraopts = -some-letter-the-author-did-not-think-of
	fill = A
	ipversion = 4
	pings =	5
	priority = 6
	size = 510
	timeout	= 1
	tos = 0xa0
	udp = no
	waittime = 1

VARIABLES
       Supported probe-specific	variables:

       binary
	   The location	of your	echoping binary.

	   Default value: /usr/bin/echoping

       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:

       extraopts
	   Any extra options specified here will be passed unmodified to
	   echoping(1).

	   Example value: -some-letter-the-author-did-not-think-of

       fill
	   The "-f" echoping(1)	option.

	   Example value: A

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

	   Example value: 4

       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

       priority
	   The "-p" echoping(1)	option.

	   Example value: 6

       size
	   The "-s" echoping(1)	option.

	   Example value: 510

       timeout
	   The "-t" echoping(1)	option.

	   Example value: 1

	   Default value: 5

       tos The "-P" echoping(1)	option.

	   Example value: 0xa0

       udp The "-u" echoping(1)	option.	Values other than '0' and 'no' enable
	   UDP.

	   Example value: no

       waittime
	   The "-w" echoping(1)	option.

	   Example value: 1
