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

OVERVIEW
       Measures	HTTP roundtrip times (web servers and caches) for SmokePing.

SYNOPSIS
	*** Probes ***

	+EchoPingHttp

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

	# The following	variables can be overridden in each target section
	accept_redirects = yes
	extraopts = -some-letter-the-author-did-not-think-of
	ignore_cache = yes
	ipversion = 4
	pings =	5
	port = 80
	priority = 6
	revalidate_data	= no
	timeout	= 20
	tos = 0xa0
	url = /
	waittime = 1

	# [...]

	*** Targets ***

	probe =	EchoPingHttp # if this should be the default probe

	# [...]

	+ mytarget
	# probe	= EchoPingHttp # if the	default	probe is something else
	host = my.host
	accept_redirects = yes
	extraopts = -some-letter-the-author-did-not-think-of
	ignore_cache = yes

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:

       accept_redirects
	   The echoping(1) "-R"	option:	Accept	HTTP  status  codes  3xx
	   (redirections) as normal responses instead of treating them as
	   errors. Note	that this option is only available starting with
	   Echoping 6.

	   Enabled if the value	is anything other than 'no' or '0'.

	   Example value: yes

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

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

       ignore_cache
	   The echoping(1) "-A"	option:	force the proxy	to ignore the cache.
	   Enabled if the value	is anything other than 'no' or '0'.

	   Example value: yes

       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

       port
	   The TCP port	to use.

	   Example value: 80

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

	   Example value: 6

       revalidate_data
	   The echoping(1) "-a"	option:	force the proxy	to revalidate data
	   with	original server. Enabled if the	value is anything other	than
	   'no'	or '0'.

	   Example value: no

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

	   Example value: 20

	   Default value: 10

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

	   Example value: 0xa0

       url The URL to be requested from	the web	server or cache. Can be	either
	   relative (/...) for web servers or absolute (http://...) for
	   caches.

	   Default value: /

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

	   Example value: 1

NOTES
       You should consider setting a lower value for the "pings" variable than
       the default 20, as repetitive URL fetching may be quite heavy on	the
       server.

       The fill, size and udp EchoPing variables are not valid for
       EchoPingHttp.
