38 Integrates FPingContinuous as a probe into smokeping. The variable
39 binary must point to your copy of the FPing program. If it is not
40 installed on your system yet, you can get a slightly enhanced version
41 from "pub" in www.smokeping.org.
42
43 The (optional) packetsize option lets you configure the packetsize for
44 the pings sent.
45
46 Continuous output is normally sent to stdout, but you can set usestdout
47 to 'false' to make smokeping read stderr instead of stdout.
48
49 The FPing manpage has the following to say on this topic:
50
51 Number of bytes of ping data to send. The minimum size (normally 12)
52 allows room for the data that fping needs to do its work (sequence
53 number, timestamp). The reported received data size includes the IP
54 header (normally 20 bytes) and ICMP header (8 bytes), so the minimum
55 total size is 40 bytes. Default is 56, as in ping. Maximum is the
56 theoretical maximum IP datagram size (64K), though most systems limit
57 this to a smaller, system-dependent number.
58
60 Supported probe-specific variables:
61
62 binary
63 The location of your fping binary.
64
65 Example value: /usr/bin/fping
66
67 This setting is mandatory.
68
69 hostinterval
70 The fping "-p" parameter, but in (possibly fractional) seconds
71 rather than milliseconds, for consistency with other Smokeping
72 probes. From fping(1):
73
74 This parameter sets the time that fping waits between successive
75 packets to an individual target.
76
77 Example value: 1.5
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 packetsize
93 The ping packet size (in the range of 12-64000 bytes).
94
95 Example value: 5000
96
97 pings
98 How many pings should be sent to each target, if different from the
99 global value specified in the Database section. Note that the
100 number of pings in the RRD files is fixed when they are originally
101 generated, and if you change this parameter afterwards, you'll have
102 to delete the old RRD files or somehow convert them.
103
104 Example value: 20
105
106 sourceaddress
107 The fping "-S" parameter . From fping(1):
108
109 Set source address.
110
111 Example value: 192.168.0.1
112
113 step
114 Duration of the base interval that this probe should use, if
115 different from the one specified in the 'Database' section. Note
116 that the step in the RRD files is fixed when they are originally
117 generated, and if you change the step parameter afterwards, you'll
118 have to delete the old RRD files or somehow convert them. (This
119 variable is only applicable if the variable 'concurrentprobes' is
120 set in the 'General' section.)
121
122 Example value: 300
123
124 timeout
125 The fping "-t" parameter, but in (possibly fractional) seconds
126 rather than milliseconds, for consistency with other Smokeping
127 probes. Note that as Smokeping uses the fping 'counting' mode (-C),
128 this apparently only affects the last ping.
129
130 Example value: 1.5
131
132 tos Set the type of service (TOS) of outgoing ICMP packets. You need
133 at laeast fping-2.4b2_to3-ipv6 for this to work. Find a copy on
134 www.smokeping.org/pub.
135
136 Example value: 0x20
137
138 usestdout
139 Listen for FPing output on stdout instead of stderr ... (continuous
140 output is normally sent to stdout).
141
142 Example value: false
