VVAARRIIAABBLLEESS
       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 dif-
           ferent from the one specified in the 'Database' section. Note that
           the step in the RRD files is fixed when they are originally gener-
           ated, 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:

       dns_request
           The DNS request (domain name) to be queried.

           Example value: example.org

           This setting is mandatory.

       dns_tcp
           The echoping_dns '--tcp' option: use only TCP ('virtual circuit').
           Enabled if specified with a value other than 'no' or '0'.

           Example value: yes

       dns_type
           The echoping_dns '-t' option: type of data requested (NS, A, SOA
           etc.)

           Example value: AAAA

           Default value: A

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

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

       ipversion
           The IP protocol used. Possible values are "4" and "6".  Passed to
           _e_c_h_o_p_i_n_g(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 num-
           ber 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

       plugin
           The echoping plugin that will be used. See _e_c_h_o_p_i_n_g(1) for details.
           This can either be the name of the plugin or a full path to the
           plugin shared object.

           Example value: /path/to/dns.so

           Default value: dns

       pluginargs
           Any extra arguments needed by the echoping plugin specified with
           the _p_l_u_g_i_n_n_a_m_e variable. These are generally provided by the sub-
           class probe.

           Example value: -p plugin_specific_arg

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

           Example value: 6

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

           Example value: 1

           Default value: 5

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

           Example value: 0xa0

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

           Example value: 1
