36 Integrates NFSping as a probe into smokeping. The variable binary must
37 point to your copy of the NFSping program.
38 NFSping can be downloaded from:
40 <https://github.com/mprovost/NFSping>
42 In blazemode, NFSping sends one more ping than requested, and discards
44 the first RTT value returned as it's likely to be an outlier.
45
47 Supported probe-specific variables:
48 binary
50 The location of your nfsping binary.
51 Example value: /usr/local/bin/nfsping
53 This setting is mandatory.
55 blazemode
57 Send an extra ping and then discard the first answer since the
58 first is bound to be an outlier.
59 Example value: true
61 hostinterval
63 The nfsping "-p" parameter, but in (possibly fractional) seconds
64 rather than milliseconds, for consistency with other Smokeping
65 probes. This parameter sets the time that nfsping waits between
66 successive packets to an individual target.
67 Example value: 1.5
69 mininterval
71 The nfsping "-i" parameter, but in (probably fractional) seconds
72 rather than milliseconds, for consistency with other Smokeping
73 probes. This is the interval between pings to successive targets.
74 Example value: 0.001
76 Default value: 0.01
78 offset
80 If you run many probes concurrently you may want to prevent them
81 from hitting your network all at the same time. Using the probe-
82 specific offset parameter you can change the point in time when
83 each probe will be run. Offset is specified in % of total interval,
84 or alternatively as 'random', and the offset from the 'General'
85 section is used if nothing is specified here. Note that this does
86 NOT influence the rrds itself, it is just a matter of when data
87 acqusition is initiated. (This variable is only applicable if the
88 variable 'concurrentprobes' is set in the 'General' section.)
89 Example value: 50%
91 pings
93 How many pings should be sent to each target, if different from the
94 global value specified in the Database section. Note that the
95 number of pings in the RRD files is fixed when they are originally
96 generated, and if you change this parameter afterwards, you'll have
97 to delete the old RRD files or somehow convert them.
98 Example value: 20
100 step
102 Duration of the base interval that this probe should use, if
103 different from the one specified in the 'Database' section. Note
104 that the step in the RRD files is fixed when they are originally
105 generated, and if you change the step parameter afterwards, you'll
106 have to delete the old RRD files or somehow convert them. (This
107 variable is only applicable if the variable 'concurrentprobes' is
108 set in the 'General' section.)
109 Example value: 300
111 tcp Use TCP insteadof UDP.
113 Example value: true
115 timeout
117 The nfsping "-t" parameter, but in (possibly fractional) seconds
118 rather than milliseconds, for consistency with other Smokeping
119 probes.
120 Example value: 1.5
