If the RRDs are already being generated, you can put symlinks from the
respective host directory to the RRDs wherever they are as long as you
have read access. Then add a section to graphs.cfg (you may need to use
'rrdtool info' to look at the variables and data) and make sure the
graph name is added to GRAPHS variable in server.cfg so they will appear
in the trends. A small gotcha is that the start of the file name of the
RRD file has to match the graph name.

For example, I just created a bunch of symlinks under various SAN
devices to point to the RRDs being generated for the interface they were
connected to on the switch:

$ ls -l /var/lib/hobbit/rrd/fc01-1.fc.ausport.gov.au/
total 40
