Thanks for the patch.  Is there something in the first line itself that might be causing the problem?

Hi, One of the problem  is that the first line is got from the do_disk.c and
it have a "/" so it's checked as a data source.
I posted a patch some days ago to solve this problem that also happen if
you use the /group with the bb command. I don't know if this alo

This will skip the first line of the do_disk message and it should then
work as expected (at least it work with /group)

Oops, I spoke too soon.  It did not work with the icons as I thought. I'm back to no icons and four data points per graph (which looks good) and the mysterious third token on the first line data point.

Indeed.  I got a suggestion to add the &clear icon to the 
heading and 
now it works.  Unfortunately I now get one very crowded graph, otherwise good progress.

Thanks for your help!

Yes, the "&color" now counts as a token, so any grep/awk/sed (or
equivalent) is going to be off by one.  Is this 
information included 
in the overall data blast from the Hobbit client?  If so, 
you might 
consider tacking the colors at the END of each line and see if the Hobbit parser starts working again.

For reference, here is something from a Solaris system:

Wed Oct 11 12:19:50 CDT 2006 - Filesystems OK
Filesystem            kbytes    used   avail capacity  Mounted on
swap                 18665136  107640 18557496     1%    /tmp
/dev/vx/dsk/rootvol  9210413 1561203 7557106    18%    /
/dev/vx/dsk/var      8263373 1775692 6405048    22%    /var
/dev/vx/dsk/opt2     34291077 2384649 31563518     8%    /opt2
/dev/vx/dsk/home     1021735  614185  346246    64%    /export/home

Notice that the filesystem is token 1, the usage is token 2, and available space is token 3, etc., etc.

These are just ideas.  I've written 7 or 8 custom tests of my own with my own RRD parsing at the end, so I quickly became acquainted with the need for agreement between the "pitcher" and the 
"catcher".
