DESCRIPTION
Integrates FPingContinuous as a probe into smokeping. The variable
binary must point to your copy of the FPing program. If it is not
installed on your system yet, you can get a slightly enhanced version
from "pub" in www.smokeping.org.
The (optional) packetsize option lets you configure the packetsize for
the pings sent.
Continuous output is normally sent to stdout, but you can set usestdout
to 'false' to make smokeping read stderr instead of stdout.
The FPing manpage has the following to say on this topic:
Number of bytes of ping data to send. The minimum size (normally 12)
allows room for the data that fping needs to do its work (sequence
number, timestamp). The reported received data size includes the IP
header (normally 20 bytes) and ICMP header (8 bytes), so the minimum
total size is 40 bytes. Default is 56, as in ping. Maximum is the
theoretical maximum IP datagram size (64K), though most systems limit
this to a smaller, system-dependent number.
VARIABLES
Supported probe-specific variables:
binary
The location of your fping binary.
Example value: /usr/bin/fping
This setting is mandatory.
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
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
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
usestdout
Listen for FPing output on stdout instead of stderr ... (continuous
output is normally sent to stdout).
Example value: false
