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 discarge the first answer since the first is bound to be an outliner.

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

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 acqusition 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

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
