46 Connect to Juniper JunOS via OpenSSH to run ping commands. This probe
47 uses the "extended ping" of the Juniper JunOS. You have the option to
48 specify which interface the ping is sourced from as well.
49
51 Supported probe-specific variables:
52 forks
54 Run this many concurrent processes at maximum
55 Example value: 5
57 Default value: 5
59 offset
61 If you run many probes concurrently you may want to prevent them
62 from hitting your network all at the same time. Using the probe-
63 specific offset parameter you can change the point in time when
64 each probe will be run. Offset is specified in % of total interval,
65 or alternatively as 'random', and the offset from the 'General'
66 section is used if nothing is specified here. Note that this does
67 NOT influence the rrds itself, it is just a matter of when data
68 acqusition is initiated. (This variable is only applicable if the
69 variable 'concurrentprobes' is set in the 'General' section.)
70 Example value: 50%
72 packetsize
74 The (optional) packetsize option lets you configure the packetsize
75 for the pings sent.
76 Default value: 100
78 step
80 Duration of the base interval that this probe should use, if
81 different from the one specified in the 'Database' section. Note
82 that the step in the RRD files is fixed when they are originally
83 generated, and if you change the step parameter afterwards, you'll
84 have to delete the old RRD files or somehow convert them. (This
85 variable is only applicable if the variable 'concurrentprobes' is
86 set in the 'General' section.)
87 Example value: 300
89 timeout
91 How long a single 'ping' takes at maximum
92 Example value: 15
94 Default value: 5
96 tos The (optional) type of service for the pings sent.
98 Supported target-specific variables:
100 junospass
102 The junospass option allows you to specify the password for the
103 username specified with the option junosuser.
104 Example value: password
106 This setting is mandatory.
108 junosuser
110 The junosuser option allows you to specify a username that has ping
111 capability on the JunOS Device.
112 Example value: user
114 This setting is mandatory.
116 pings
118 How many pings should be sent to each target, if different from the
119 global value specified in the Database section. Note that the
120 number of pings in the RRD files is fixed when they are originally
121 generated, and if you change this parameter afterwards, you'll have
122 to delete the old RRD files or somehow convert them.
123 Example value: 5
125 psource
127 The (optional) psource option specifies an alternate IP address or
128 Interface from which you wish to source your pings from. Routers
129 can have many many IP addresses, and interfaces. When you ping
130 from a router you have the ability to choose which interface and/or
131 which IP address the ping is sourced from. Specifying an
132 IP/interface does not necessarily specify the interface from which
133 the ping will leave, but will specify which address the packet(s)
134 appear to come from. If this option is left out the JunOS Device
135 will source the packet automatically based on routing and/or
136 metrics. If this doesn't make sense to you then just leave it out.
137 Example value: 192.168.2.129
139 source
141 The source option specifies the JunOS device that is going to run
142 the ping commands. This address will be used for the ssh
143 connection.
144 Example value: 192.168.2.1
146 This setting is mandatory.

156 JunOS configuration
157 The JunOS device should have a username/password configured, as well as
158 the ability to connect to the VTY(s).
159 Make sure to connect to the remote host once from the commmand line as
161 the user who is running smokeping. On the first connect ssh will ask to
162 add the new host to its known_hosts file. This will not happen
163 automatically so the script will fail to login until the ssh key of
164 your juniper box is in the known_hosts file.
165 Some JunOS devices have a maximum of 5 VTYs available, so be careful
167 not to hit a limit with the 'forks' variable.
168 Requirements
170 This module requires the Net::OpenSSH and IO::Pty.
