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

70 Supported probe-specific variables:
71 binary
73 The location of your fping binary.
74 Example value: /usr/bin/fping
76 This setting is mandatory.
78 blazemode
80 Send an extra ping and then discard the first answer since the
81 first is bound to be an outlier.
82 Example value: true
84 hostinterval
86 The fping "-p" parameter, but in (possibly fractional) seconds
87 rather than milliseconds, for consistency with other Smokeping
88 probes. From fping(1):
89 This parameter sets the time that fping waits between successive
91 packets to an individual target.
92 Example value: 1.5
94 interface
96 The name of the network interface to perform the ping on.
97 Example value: eth0
99 mininterval
101 The fping "-i" parameter, but in (probably fractional) seconds
102 rather than milliseconds, for consistency with other Smokeping
103 probes. From fping(1):
104 The minimum amount of time between sending a ping packet to any
106 target.
107 Example value: 0.001
109 Default value: 0.01
111 offset
113 If you run many probes concurrently you may want to prevent them
114 from hitting your network all at the same time. Using the probe-
115 specific offset parameter you can change the point in time when
116 each probe will be run. Offset is specified in % of total interval,
117 or alternatively as 'random', and the offset from the 'General'
118 section is used if nothing is specified here. Note that this does
119 NOT influence the rrds itself, it is just a matter of when data
120 acquisition is initiated. (This variable is only applicable if the
121 variable 'concurrentprobes' is set in the 'General' section.)
122 Example value: 50%
124 packetsize
126 The ping packet size (in the range of 12-64000 bytes).
127 Example value: 5000
129 pings
131 How many pings should be sent to each target, if different from the
132 global value specified in the Database section. Note that the
133 number of pings in the RRD files is fixed when they are originally
134 generated, and if you change this parameter afterwards, you'll have
135 to delete the old RRD files or somehow convert them.
136 Example value: 20
138 protocol
140 Choose if the ping should use IPv4 or IPv6.
141 Example value: 4
143 sourceaddress
145 The fping "-S" parameter . From fping(1):
146 Set source address.
148 Example value: 192.168.0.1
150 step
152 Duration of the base interval that this probe should use, if
153 different from the one specified in the 'Database' section. Note
154 that the step in the RRD files is fixed when they are originally
155 generated, and if you change the step parameter afterwards, you'll
156 have to delete the old RRD files or somehow convert them. (This
157 variable is only applicable if the variable 'concurrentprobes' is
158 set in the 'General' section.)
159 Example value: 300
161 timeout
163 The fping "-t" parameter, but in (possibly fractional) seconds
164 rather than milliseconds, for consistency with other Smokeping
165 probes. Note that as Smokeping uses the fping 'counting' mode (-C),
166 this apparently only affects the last ping.
167 Example value: 1.5
169 tos Set the type of service (TOS) of outgoing ICMP packets. You need
171 at laeast fping-2.4b2_to3-ipv6 for this to work. Find a copy on
172 www.smokeping.org/pub.
173 Example value: 0x20
175 usestdout
177 Listen for FPing output on stdout instead of stderr ... (version
178 3.3+ sends its statistics on stdout).
179 Example value: true
