DESCRIPTION

36       Integrates NFSping as a probe into smokeping. The variable binary must
37       point to your copy of the NFSping program.
38
39       NFSping can be downloaded from:
40
41       <https://github.com/mprovost/NFSping>
42
43       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.

VARIABLES

47       Supported probe-specific variables:
48
49       binary
50           The location of your nfsping binary.
51
52           Example value: /usr/local/bin/nfsping
53
54           This setting is mandatory.
55
56       blazemode
57           Send an extra ping and then discard the first answer since the
58           first is bound to be an outlier.
59
60           Example value: true
61
62       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
68           Example value: 1.5
69
70       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
75           Example value: 0.001
76
77           Default value: 0.01
78
79       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
90           Example value: 50%
91
92       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
99           Example value: 20
100
101       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
110           Example value: 300
111
112       tcp Use TCP insteadof UDP.
113
114           Example value: true
115
116       timeout
117           The nfsping "-t" parameter, but in (possibly fractional) seconds
118           rather than milliseconds, for consistency with other Smokeping
119           probes.
120
121           Example value: 1.5
