DESCRIPTION

       Connect to Juniper JunOS via OpenSSH to run ping commands.  This probe uses the "extended
       ping" of the Juniper JunOS.  You have the option to specify which interface the ping is
       sourced from as well.

VARIABLES

       Supported probe-specific variables:

       forks
           Run this many concurrent processes at maximum

           Example value: 5

           Default value: 5

       offset
           If you run many probes concurrently you may want to prevent them from hitting your
           network all at the same time. Using the probe-specific offset parameter you can change
           the point in time when each probe will be run. Offset is specified in % of total
           interval, or alternatively as 'random', and the offset from the 'General' section is
           used if nothing is specified here. Note that this does NOT influence the rrds itself,
           it is just a matter of when data acqusition is initiated.  (This variable is only
           applicable if the variable 'concurrentprobes' is set in the 'General' section.)

           Example value: 50%

       packetsize
           The (optional) packetsize option lets you configure the packetsize for the pings sent.

           Default value: 100

       step
           Duration of the base interval that this probe should use, if different from the one
           specified in the 'Database' section. Note that the step in the RRD files is fixed when
           they are originally generated, and if you change the step parameter afterwards, you'll
           have to delete the old RRD files or somehow convert them. (This variable is only
           applicable if the variable 'concurrentprobes' is set in the 'General' section.)

           Example value: 300

       timeout
           How long a single 'ping' takes at maximum

           Example value: 15

           Default value: 5

       Supported target-specific variables:

       junospass
           The junospass option allows you to specify the password for the username specified
           with the option junosuser.

           Example value: password

           This setting is mandatory.

       junosuser
           The junosuser option allows you to specify a username that has ping capability on the
           JunOS Device.

           Example value: user

           This setting is mandatory.

       pings
           How many pings should be sent to each target, if different from the global value
           specified in the Database section. Note that the number of pings in the RRD files is
           fixed when they are originally generated, and if you change this parameter afterwards,
           you'll have to delete the old RRD files or somehow convert them.

           Example value: 5

       psource
           The (optional) psource option specifies an alternate IP address or Interface from
           which you wish to source your pings from.  Routers can have many many IP addresses,
           and interfaces.  When you ping from a router you have the ability to choose which
           interface and/or which IP address the ping is sourced from.  Specifying an
           IP/interface does not necessarily specify the interface from which the ping will
           leave, but will specify which address the packet(s) appear to come from.  If this
           option is left out the JunOS Device will source the packet automatically based on
           routing and/or metrics.  If this doesn't make sense to you then just leave it out.

           Example value: 192.168.2.129

       source
           The source option specifies the JunOS device that is going to run the ping commands.
           This address will be used for the ssh connection.

           Example value: 192.168.2.1

           This setting is mandatory.

NOTES

   JunOS configuration
       The JunOS device should have a username/password configured, as well as the ability to
       connect to the VTY(s).

       Make sure to connect to the remote host once from the commmand line as the user who is
       running smokeping. On the first connect ssh will ask to add the new host to its
       known_hosts file. This will not happen automatically so the script will fail to login
       until the ssh key of your juniper box is in the known_hosts file.

       Some JunOS devices have a maximum of 5 VTYs available, so be careful not to hit a limit
       with the 'forks' variable.

   Requirements
       This module requires the  Net::OpenSSH and IO::Pty.
