40 Integrates ssh-keyscan as a probe into smokeping. The variable binary
41 must point to your copy of the ssh-keyscan program. If it is not
42 installed on your system yet, you should install openssh >= 3.8p1
43
44 The Probe asks the given host n-times for it's public key, where n is
45 the amount specified in the config File.
46
47 As part of the initialization, the probe asks 127.0.0.1 for it's public
48 key and tries to parse the output. Make sure you have SSH running on
49 the localhost as well.
50
52 Supported probe-specific variables:
53
54 binary
55 The location of your ssh-keyscan binary.
56
57 Example value: /usr/bin/ssh-keyscan
58
59 This setting is mandatory.
60
61 forks
62 Run this many concurrent processes at maximum
63
64 Example value: 5
65
66 Default value: 5
67
68 offset
69 If you run many probes concurrently you may want to prevent them
70 from hitting your network all at the same time. Using the probe-
71 specific offset parameter you can change the point in time when
72 each probe will be run. Offset is specified in % of total interval,
73 or alternatively as 'random', and the offset from the 'General'
74 section is used if nothing is specified here. Note that this does
75 NOT influence the rrds itself, it is just a matter of when data
76 acqusition is initiated. (This variable is only applicable if the
77 variable 'concurrentprobes' is set in the 'General' section.)
78
79 Example value: 50%
80
81 step
82 Duration of the base interval that this probe should use, if
83 different from the one specified in the 'Database' section. Note
84 that the step in the RRD files is fixed when they are originally
85 generated, and if you change the step parameter afterwards, you'll
86 have to delete the old RRD files or somehow convert them. (This
87 variable is only applicable if the variable 'concurrentprobes' is
88 set in the 'General' section.)
89
90 Example value: 300
91
92 timeout
93 How long a single 'ping' takes at maximum
94
95 Example value: 15
96
97 Default value: 5
98
99 Supported target-specific variables:
100
101 keytype
102 Type of key, used in ssh-keyscan -t keytype
103
104 Example value: dsa
105
106 Default value: rsa
107
108 pings
109 How many pings should be sent to each target, if different from the
110 global value specified in the Database section. Note that the
111 number of pings in the RRD files is fixed when they are originally
112 generated, and if you change this parameter afterwards, you'll have
113 to delete the old RRD files or somehow convert them.
114
115 Example value: 5
116
117 port
118 Port to use when testing the ssh connection -p port
119
120 Example value: 5000
121
122 Default value: 22
