DESCRIPTION

39       Integrates FPing as a probe into smokeping. The variable binary must
40       point to your copy of the FPing program.  If it is not installed on
41       your system yet, you can get a slightly enhanced version from "pub" in
42       www.smokeping.org.
43
44       The (optional) packetsize option lets you configure the packetsize for
45       the pings sent.
46
47       Since version 3.3 fping sends its statistics to stdout. Set usestdout
48       to 'true' so make smokeping read stdout instead of stderr.
49
50       In blazemode, FPing sends one more ping than requested, and discards
51       the first RTT value returned as it's likely to be an outlier.
52
53       The FPing manpage has the following to say on this topic:
54
55       Number of bytes of ping data to send.  The minimum size (normally 12)
56       allows room for the data that fping needs to do its work (sequence
57       number, timestamp).  The reported received data size includes the IP
58       header (normally 20 bytes) and ICMP header (8 bytes), so the minimum
59       total size is 40 bytes.  Default is 56, as in ping. Maximum is the
60       theoretical maximum IP datagram size (64K), though most systems limit
61       this to a smaller, system-dependent number.

VARIABLES

64       Supported probe-specific variables:
65
66       binary
67           The location of your fping binary.
68
69           Example value: /usr/bin/fping
70
71           This setting is mandatory.
72
73       blazemode
74           Send an extra ping and then discarge the first answer since the
75           first is bound to be an outliner.
76
77           Example value: true
78
79       hostinterval
80           The fping "-p" parameter, but in (possibly fractional) seconds
81           rather than milliseconds, for consistency with other Smokeping
82           probes. From fping(1):
83
84           This parameter sets the time that fping  waits between successive
85           packets to an individual target.
86
87           Example value: 1.5
88
89       mininterval
90           The fping "-i" parameter, but in (probably fractional) seconds
91           rather than milliseconds, for consistency with other Smokeping
92           probes. From fping(1):
93
94           The minimum amount of time between sending a ping packet to any
95           target.
96
97           Example value: 0.001
98
99           Default value: 0.01
100
101       offset
102           If you run many probes concurrently you may want to prevent them
103           from hitting your network all at the same time. Using the probe-
104           specific offset parameter you can change the point in time when
105           each probe will be run. Offset is specified in % of total interval,
106           or alternatively as 'random', and the offset from the 'General'
107           section is used if nothing is specified here. Note that this does
108           NOT influence the rrds itself, it is just a matter of when data
109           acqusition is initiated.  (This variable is only applicable if the
110           variable 'concurrentprobes' is set in the 'General' section.)
111
112           Example value: 50%
113
114       packetsize
115           The ping packet size (in the range of 12-64000 bytes).
116
117           Example value: 5000
118
119       pings
120           How many pings should be sent to each target, if different from the
121           global value specified in the Database section. Note that the
122           number of pings in the RRD files is fixed when they are originally
123           generated, and if you change this parameter afterwards, you'll have
124           to delete the old RRD files or somehow convert them.
125
126           Example value: 20
127
128       sourceaddress
129           The fping "-S" parameter . From fping(1):
130
131           Set source address.
132
133           Example value: 192.168.0.1
134
135       step
136           Duration of the base interval that this probe should use, if
137           different from the one specified in the 'Database' section. Note
138           that the step in the RRD files is fixed when they are originally
139           generated, and if you change the step parameter afterwards, you'll
140           have to delete the old RRD files or somehow convert them. (This
141           variable is only applicable if the variable 'concurrentprobes' is
142           set in the 'General' section.)
143
144           Example value: 300
145
146       timeout
147           The fping "-t" parameter, but in (possibly fractional) seconds
148           rather than milliseconds, for consistency with other Smokeping
149           probes. Note that as Smokeping uses the fping 'counting' mode (-C),
150           this apparently only affects the last ping.
151
152           Example value: 1.5
153
154       tos Set the type of service (TOS) of outgoing ICMP packets.  You need
155           at laeast fping-2.4b2_to3-ipv6 for this to work. Find a copy on
156           www.smokeping.org/pub.
157
158           Example value: 0x20
159
160       usestdout
161           Listen for FPing output on stdout instead of stderr ... (version
162           3.3+ sends its statistics on stdout).
163
164           Example value: true
