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.
