DESCRIPTION
Integrates the remote execution of FPing via ssh/rsh into smokeping. The variable binary must point to your copy of the ssh/rsh program.
The variable rbinary must point to your copy of the fping program at the remote end.
VARIABLES
Supported probe-specific variables:
binary
This variable specifies the path of the remote shell program (usually ssh, rsh or remsh). Any other script or binary that can be called
as
binary [ -l ruser ] rhost rbinary
may be used.
Example value: /usr/bin/ssh
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
rbinary
The location of your fping binary.
Example value: /usr/bin/fping
This setting is mandatory.
rhost
The rhost option specifies the remote device from where fping will be launched.
Example value: my.pinger.host
This setting is mandatory.
ruser
The (optional) ruser option allows you to specify the remote user, if different from the one running the smokeping daemon.
Example value: foo
sourceaddress
The fping "-S" parameter . From fping(1):
Set source address.
Example value: 192.168.0.1
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

NOTES
It is important to make sure that you can access the remote machine without a password prompt, otherwise this probe will not work properly.
To test just try something like this:
$ ssh foo@HostA.foobar.com fping HostB.barfoo.com
The next thing you see must be fping's output.
The rhost, ruser and rbinary variables used to be configured in the Targets section of the first target or its parents They were moved to
the Probes section, because the variables aren't really target-specific (all the targets are measured with the same parameters). The
Targets sections aren't recognized anymore.
BUGS
This functionality should be in a generic 'remote execution' module so that it could be used for the other probes too.
