These are actually "just" signs of you restarting Hobbit.

This one is a bit odd, but shouldn't prevent you from seeing any graphs.
The message indicates that you do in fact have the RRD files used to track 
the data (these are in the ~hobbit/data/rrd/ directory - or 
/var/lib/hobbit/rrd if you used the RPM install). So that part,
collecting the data, is working.

The most common reason for graphs not appearing appears to be that the
CGI program generating the graphs cannot find one of the libraries it
needs (the rrdtool "librrd.so.*" library). Or if you have installed
a newer version of rrdtool yourself, but the older version is still
available elsewhere on your system.

Try this: Do an "su - www-data" (or whatever userid your webserver
uses) to get the real environment setup. Then run

   REQUEST_METHOD=GET SCRIPT_NAME="hobbitgraph.sh" \
   QUERY_STRING="host=toro&service=bbd&action=view&graph=hourly" \
   ~hobbit/cgi-bin/hobbitgraph.sh

This should provide some more insight into why the graphs won't show up.
