This server/ext script walks the FPing targets from your existing Smokeping installation and alerts if the packet loss exceeds a threshold. It's similar in concept to the bbmrtg.pl script.

  1. Make sure your Xymon/BB hostnames and Smokeping hostnames are in agreement, eg.
       /usr/local/hobbit/server/etc/bb-hosts:
          10.20.30.40   myrouter     # conn
    
       /usr/local/smokeping/etc/config:
          ++ myrouter
          menu = myrouter
          title = This Is My Router
          host = 10.20.30.40
  2. Then drop this ext script into /usr/local/hobbit/server/ext and enable it in the launcher, eg add this to /usr/local/hobbit/server/etc/hobbitlaunch.cfg
       [bbsmokeping]
          ENVFILE /usr/local/hobbit/server/etc/hobbitserver.cfg
          NEEDS hobbitd
          CMD $BBHOME/ext/bbsmokeping.pl
          LOGFILE $BBSERVERLOGS/bbsmokeping.log
          INTERVAL 3m
