48 Connect to Juniper JunOS via OpenSSH to run ping commands. This probe
49 uses the "extended ping" of the Juniper JunOS. You have the option to
50 specify which interface the ping is sourced from as well.
51
53 Supported probe-specific variables:
54
55 forks
56 Run this many concurrent processes at maximum
57
58 Example value: 5
59
60 Default value: 5
61
62 offset
63 If you run many probes concurrently you may want to prevent them
64 from hitting your network all at the same time. Using the probe-
65 specific offset parameter you can change the point in time when
66 each probe will be run. Offset is specified in % of total interval,
67 or alternatively as 'random', and the offset from the 'General'
68 section is used if nothing is specified here. Note that this does
69 NOT influence the rrds itself, it is just a matter of when data
70 acquisition is initiated. (This variable is only applicable if the
71 variable 'concurrentprobes' is set in the 'General' section.)
72
73 Example value: 50%
74
75 packetsize
76 The (optional) packetsize option lets you configure the packetsize
77 for the pings sent.
78
79 Default value: 100
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 tos The (optional) type of service for the pings sent.
100
101 Supported target-specific variables:
102
103 /^influx_.+/
104 This is a tag that will be sent to influxdb and has no impact on
105 the probe measurement. The tag name will be sent without the
106 "influx_" prefix, which will be replaced with "tag_" instead. Tags
107 can be used for filtering.
108
109 Example value: influx_location = In the basement
110
111 junospass
112 The junospass option allows you to specify the password for the
113 username specified with the option junosuser.
114
115 Example value: password
116
117 This setting is mandatory.
118
119 junosuser
120 The junosuser option allows you to specify a username that has ping
121 capability on the JunOS Device.
122
123 Example value: user
124
125 This setting is mandatory.
126
127 pings
128 How many pings should be sent to each target, if different from the
129 global value specified in the Database section. Note that the
130 number of pings in the RRD files is fixed when they are originally
131 generated, and if you change this parameter afterwards, you'll have
132 to delete the old RRD files or somehow convert them.
133
134 Example value: 5
135
136 psource
137 The (optional) psource option specifies an alternate IP address or
138 Interface from which you wish to source your pings from. Routers
139 can have many many IP addresses, and interfaces. When you ping
140 from a router you have the ability to choose which interface and/or
141 which IP address the ping is sourced from. Specifying an
142 IP/interface does not necessarily specify the interface from which
143 the ping will leave, but will specify which address the packet(s)
144 appear to come from. If this option is left out the JunOS Device
145 will source the packet automatically based on routing and/or
146 metrics. If this doesn't make sense to you then just leave it out.
147
148 Example value: 192.168.2.129
149
150 source
151 The source option specifies the JunOS device that is going to run
152 the ping commands. This address will be used for the ssh
153 connection.
154
155 Example value: 192.168.2.1
156
157 This setting is mandatory.

164
166 JunOS configuration
167 The JunOS device should have a username/password configured, as well as
168 the ability to connect to the VTY(s).
169
170 Make sure to connect to the remote host once from the command line as
171 the user who is running smokeping. On the first connect ssh will ask to
172 add the new host to its known_hosts file. This will not happen
173 automatically so the script will fail to login until the ssh key of
174 your juniper box is in the known_hosts file.
175
176 Some JunOS devices have a maximum of 5 VTYs available, so be careful
177 not to hit a limit with the 'forks' variable.
178
179 Requirements
180 This module requires the Net::OpenSSH and IO::Pty.
