[hobbit] Representing disk data for graphing

No, the problem is not the root filesystem, the problem is that
do_disk.c recognize a disk line if that line contains a "/" inside the
line and will skip that line if it start with "&" and it will skip the
line if it contains the string "red" or "yellow".
This is mostly done for Unix filesystem report that looks something
like:
yellow Wed Oct 11 21:55:16 CEST 2006 - Filesystems NOT ok
&yellow /sapdata/QQ8 (94% used) has reached the WARNING level (90%)
Filesystem kbytes used avail capacity Mounted on
swap 15566048 160 15565888 1% /var/run
swap 15807304 241416 15565888 2% /tmp
/dev/md/dsk/d0 20645791 6351115 14088219 32% /
/dev/md/dsk/d2 35009161 2241510 32417560 7% /sapexe
In this case it need to skip line starting with "&red" or "&yellow"
because they are only the alert at the start of the message so that
users know with a direct look what's wrong. Those line have to be
skipped.
So a line containing a "/" and not containing a "&" at the start or the
word yellow and red will not be skipped.
I think that you've to change the way you send data because probably the
line with data you send will be skipped if they're reported to hobbit
with "&red" or "&yellow" too.
You can use something like the test I pasted above to send data that
should be recognized as unix filesystem.
