[hobbit] logic dependencies and combined to alerts

I have fping installed and my hobbit install had the --ping option for
bbtest-net enabled by default in hobbitlaunch.cfg.

Yes the way you have shown it will work. Status messages from downed
hosts with route should then show what it relies on is down and report

Why do you want clear? Surely it should still show a warning at these
switches being down but the one in red being the main concern. There may
be an option to change this colour to "clear" in hobbitserver.cfg,
haven't checked though.

Hi Craig,

thanks for the fast answer.

"route" is a tag which follows "ip name # service"
out of that and the "man explanation" i could form 
chains starting with SPF? SPF # Switch1 #     route:SPF Switch2 #     route:SPF Switch2.1 #   route:SPF,Switch2 Switch2.2 #   route:SPF,Switch2 Switch2.2.1 # route:SPF,Switch2,Switch2.2 Switch3 #     route:SPF

Will this work?
In the man page is qouted that the
option has to be used somewhere...
is --ping the default or do i need do recompile?

This would be a possible workaround...but not a real
satisfying state, cause status is changed to yellow
and not "clear" on failingchains.
