45 Integrates Cisco IOS as a probe into smokeping. Uses the rsh / remsh
46 protocol to run a ping from an IOS device.
47
49 Supported probe-specific variables:
50 binary
52 The binary option specifies the path of the binary to be used to
53 connect to the IOS device. Commonly used binaries are /usr/bin/rsh
54 and /usr/bin/remsh, although any script or binary should work if
55 can be called as
56 /path/to/binary [ -l user ] router ping
58 to produce the IOS ping dialog on stdin & stdout.
60 Example value: /usr/bin/rsh
62 This setting is mandatory.
64 forks
66 Run this many concurrent processes at maximum
67 Example value: 5
69 Default value: 5
71 offset
73 If you run many probes concurrently you may want to prevent them
74 from hitting your network all at the same time. Using the probe-
75 specific offset parameter you can change the point in time when
76 each probe will be run. Offset is specified in % of total interval,
77 or alternatively as 'random', and the offset from the 'General'
78 section is used if nothing is specified here. Note that this does
79 NOT influence the rrds itself, it is just a matter of when data
80 acquisition is initiated. (This variable is only applicable if the
81 variable 'concurrentprobes' is set in the 'General' section.)
82 Example value: 50%
84 packetsize
86 The (optional) packetsize option lets you configure the packetsize
87 for the pings sent.
88 Default value: 56
90 step
92 Duration of the base interval that this probe should use, if
93 different from the one specified in the 'Database' section. Note
94 that the step in the RRD files is fixed when they are originally
95 generated, and if you change the step parameter afterwards, you'll
96 have to delete the old RRD files or somehow convert them. (This
97 variable is only applicable if the variable 'concurrentprobes' is
98 set in the 'General' section.)
99 Example value: 300
101 timeout
103 How long a single 'ping' takes at maximum
104 Example value: 15
106 Default value: 5
108 Supported target-specific variables:
110 /^influx_.+/
112 This is a tag that will be sent to influxdb and has no impact on
113 the probe measurement. The tag name will be sent without the
114 "influx_" prefix, which will be replaced with "tag_" instead. Tags
115 can be used for filtering.
116 Example value: influx_location = In the basement
118 ioshost
120 The ioshost option specifies the IOS device which should be used
121 for the ping.
122 Example value: my.cisco.router
124 This setting is mandatory.
126 iosint
128 The (optional) iosint option allows you to specify the source
129 address or interface in the IOS device. The value should be an IP
130 address or an interface name such as "Ethernet 1/0". If this option
131 is omitted, the IOS device will pick the IP address of the outbound
132 interface to use.
133 Example value: Ethernet 1/0
135 iosuser
137 The (optional) iosuser option allows you to specify the remote
138 username the IOS device. If this option is omitted, the username
139 defaults to the default user used by the remsh command (usually the
140 user running the remsh command, ie the user running SmokePing).
141 Example value: admin
143 pings
145 How many pings should be sent to each target, if different from the
146 global value specified in the Database section. Note that the
147 number of pings in the RRD files is fixed when they are originally
148 generated, and if you change this parameter afterwards, you'll have
149 to delete the old RRD files or somehow convert them.
150 Example value: 5

161 IOS Configuration
162 The IOS device must have rsh enabled and an appropriate trust defined,
163 eg:
164 !
166 ip rcmd rsh-enable
167 ip rcmd remote-host smoke 192.168.1.2 smoke enable
168 !
169 Some IOS devices have a maximum of 5 VTYs available, so be careful not
171 to hit a limit with the 'forks' variable.
172 Password authentication
174 It is not possible to use password authentication with rsh or remsh due
175 to fundamental limitations of the protocol.
176 Ping packet size
178 The FPing manpage has the following to say on the topic of ping packet
179 size:
180 Number of bytes of ping data to send. The minimum size (normally 12)
182 allows room for the data that fping needs to do its work (sequence
183 number, timestamp). The reported received data size includes the IP
184 header (normally 20 bytes) and ICMP header (8 bytes), so the minimum
185 total size is 40 bytes. Default is 56, as in ping. Maximum is the
186 theoretical maximum IP datagram size (64K), though most systems limit
187 this to a smaller, system-dependent number.
