NAME
       Smokeping::probes::NFSping - NFSping Probe for SmokePing

SYNOPSIS
        *** Probes ***

        +NFSping

        binary = /usr/local/bin/nfsping # mandatory
        blazemode = true
        hostinterval = 1.5
        mininterval = 0.001
        offset = 50%
        pings = 20
        step = 300
        timeout = 1.5

        # [...]

        *** Targets ***

        probe = NFSping # if this should be the default probe

        # [...]

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

DESCRIPTION
       Integrates NFSping as a probe into smokeping. The variable binary must
       point to your copy of the NFSping program.

       NFSping can be downloaded from:

       <https://github.com/mprovost/NFSping>

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

VARIABLES
       Supported probe-specific variables:

       binary
           The location of your nfsping binary.

           Example value: /usr/local/bin/nfsping

           This setting is mandatory.

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

           Example value: true

       hostinterval
           The nfsping "-p" parameter, but in (possibly fractional) seconds
           rather than milliseconds, for consistency with other Smokeping
           probes. This parameter sets the time that nfsping  waits between
           successive packets to an individual target.

           Example value: 1.5

       mininterval
           The nfsping "-i" parameter, but in (probably fractional) seconds
           rather than milliseconds, for consistency with other Smokeping
           probes. This is the interval between pings to successive targets.

           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%

       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

       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 nfsping "-t" parameter, but in (possibly fractional) seconds
           rather than milliseconds, for consistency with other Smokeping
           probes.

           Example value: 1.5
