Not right now. I might come up with something equivalent one day,
but it isn't there now.

Looking at the script, I think it should be possible to make it work
with Hobbit for someone with a bit of Perl knowledge (i.e. not
me!). Some of the changes that need to be done are:

- instead of reading the hostnames from bb-hosts directly, run
  bbhostshow and read them from there. That will make it work with
  hosts-files that use include's.

- Either assume the environment is setup already (put a shell 
  wrapper around larrd-graphs), or load it from the hobbitserver.cfg
  file. I dont think you need the larrd config-file, except for
  the BBRRDS variable which can easily be set in the script.

- Call the hobbitgraph.cgi CGI instead of larrd-grapher.cgi. The
  query-string parameters are the same, except for disk_part

I cannot quite figure out if it scans the directory for the LARRD
rrd-files; if it does, then that will need some work since Hobbit
stores files differently.
