DESCRIPTION

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

VARIABLES

65       Supported probe-specific variables:
66
67       binary
68           The location of your fping binary.
69
70           Example value: /usr/bin/fping
71
72           This setting is mandatory.
73
74       blazemode
75           Send an extra ping and then discarge the first answer since the
76           first is bound to be an outliner.
77
78           Example value: true
79
80       hostinterval
81           The fping "-p" parameter, but in (possibly fractional) seconds
82           rather than milliseconds, for consistency with other Smokeping
83           probes. From fping(1):
84
85           This parameter sets the time that fping  waits between successive
86           packets to an individual target.
87
88           Example value: 1.5
89
90       mininterval
91           The fping "-i" parameter, but in (probably fractional) seconds
92           rather than milliseconds, for consistency with other Smokeping
93           probes. From fping(1):
94
95           The minimum amount of time between sending a ping packet to any
96           target.
97
98           Example value: 0.001
99
100           Default value: 0.01
101
102       offset
103           If you run many probes concurrently you may want to prevent them
104           from hitting your network all at the same time. Using the probe-
105           specific offset parameter you can change the point in time when
106           each probe will be run. Offset is specified in % of total interval,
107           or alternatively as 'random', and the offset from the 'General'
108           section is used if nothing is specified here. Note that this does
109           NOT influence the rrds itself, it is just a matter of when data
110           acqusition is initiated.  (This variable is only applicable if the
111           variable 'concurrentprobes' is set in the 'General' section.)
112
113           Example value: 50%
114
115       packetsize
116           The ping packet size (in the range of 12-64000 bytes).
117
118           Example value: 5000
119
120       pings
121           How many pings should be sent to each target, if different from the
122           global value specified in the Database section. Note that the
123           number of pings in the RRD files is fixed when they are originally
124           generated, and if you change this parameter afterwards, you'll have
125           to delete the old RRD files or somehow convert them.
126
127           Example value: 20
128
129       protocol
130           Choose if the ping should use IPv4 or IPv6.
131
132           Example value: 4
133
134           Default value: 4
135
136       sourceaddress
137           The fping "-S" parameter . From fping(1):
138
139           Set source address.
140
141           Example value: 192.168.0.1
142
143       step
144           Duration of the base interval that this probe should use, if
145           different from the one specified in the 'Database' section. Note
146           that the step in the RRD files is fixed when they are originally
147           generated, and if you change the step parameter afterwards, you'll
148           have to delete the old RRD files or somehow convert them. (This
149           variable is only applicable if the variable 'concurrentprobes' is
150           set in the 'General' section.)
151
152           Example value: 300
153
154       timeout
155           The fping "-t" parameter, but in (possibly fractional) seconds
156           rather than milliseconds, for consistency with other Smokeping
157           probes. Note that as Smokeping uses the fping 'counting' mode (-C),
158           this apparently only affects the last ping.
159
160           Example value: 1.5
161
162       tos Set the type of service (TOS) of outgoing ICMP packets.  You need
163           at laeast fping-2.4b2_to3-ipv6 for this to work. Find a copy on
164           www.smokeping.org/pub.
165
166           Example value: 0x20
167
168       usestdout
169           Listen for FPing output on stdout instead of stderr ... (version
170           3.3+ sends its statistics on stdout).
171
172           Example value: true
