```

## DESCRIPTION

Integrates FPing6 as a probe into smokeping. This probe is derived from FPing; the only difference is that the target host used for checking the fping command output is ::1 instead of localhost.

## VARIABLES

Supported probe-specific variables:

- binary

  The location of your fping binary.

  Example value: /usr/bin/fping6

  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 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

- interface

  The name of the network interface to perform the ping on.

  Example value: eth0

- 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 acquisition 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

- protocol

  Choose if the ping should use IPv4 or IPv6.

  Example value: 6

  Default value: 6

- sourceaddress

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

  Set source address.

  Example value: ::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
