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 The (optional) packetsize option lets you configure the packetsize for
46 the pings sent.
47 Since version 3.3 fping sends its statistics to stdout. Set usestdout
49 to 'true' so make smokeping read stdout instead of stderr.
50 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 The FPing manpage has the following to say on this topic:
55 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.
63
65 Supported probe-specific variables:
66 binary
68 The location of your fping binary.
69 Example value: /usr/bin/fping
71 This setting is mandatory.
73 blazemode
75 Send an extra ping and then discarge the first answer since the
76 first is bound to be an outliner.
77 Example value: true
79 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 This parameter sets the time that fping waits between successive
86 packets to an individual target.
87 Example value: 1.5
89 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 The minimum amount of time between sending a ping packet to any
96 target.
97 Example value: 0.001
99 Default value: 0.01
101 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 Example value: 50%
114 packetsize
116 The ping packet size (in the range of 12-64000 bytes).
117 Example value: 5000
119 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 Example value: 20
128 protocol
130 Choose if the ping should use IPv4 or IPv6.
131 Example value: 4
133 Default value: 4
135 sourceaddress
137 The fping "-S" parameter . From fping(1):
138 Set source address.
140 Example value: 192.168.0.1
142 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 Example value: 300
153 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 Example value: 1.5
161 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 Example value: 0x20
167 usestdout
169 Listen for FPing output on stdout instead of stderr ... (version
170 3.3+ sends its statistics on stdout).
171 Example value: true
