[hobbit] Monitor/graph multiple interfaces with Hobbit?

[Jeremy Worrells]

Thanks, Henrik. I will look into some custom scripts. 

One more question: Is is possible to monitor multiple items with a
single bulb on the status page? For instance, a firewall with 4
interfaces would have a single status bulb for "interfaces".

It's not available "out of the box" - you'll have to write some scripts
to collect the data you're after, check it against the thresholds, and
sends the result of that check to Hobbit as a status message. This
status can then include the raw data which can go into a graph shown by
Hobbit.

What you're asking for doesn't seem terribly out of the ordinary, so it
would make sense to provide this as a standard part of Hobbit. 
A merge of MRTG's data collection with Hobbit's alerting and graph
features would be a pretty powerful setup.

I do have plans for Hobbit to trigger alerts based on the data that is
reported into the RRD files, which would take care of the alerting part
of your scenario. Then there's the SNMP-based data collection; a user
from Belgium has done some work on this so there might be something
available soon.

So - it will happen one day. But it's not there yet.
