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
