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
