[hobbit] Representing disk data for graphing

Not really a problem I think but some misinterpretation by the do_disk.c
that is happening if the first line have a "/" 
your first line is:
"color" 11 Oct 2006 07:45:23 Disk/SFS Utilization OK 

I added "color" because it's passed also if you don't see it on the
first line because it's the page color.
The line checking the various line of disk report to get data line are:


                /* AS/400 reports must contain the word DASD */
                if ((dsystype == DT_AS400) && (strstr(curline, "DASD")
== NULL)) goto nextline;

                /* All clients except AS/400 report the mount-point with
slashes - ALSO Win32 clients. */
                if ((dsystype != DT_AS400) && (strchr(curline, '/') ==
NULL)) goto nextline;

                /* red/yellow filesystems show up twice */
-->                if ((dsystype != DT_NETAPP) && (dsystype !=
DT_NETWARE) && (dsystype != DT_AS400)) {
-->                        if (*curline == '&') goto nextline;
-->                        if ((strstr(curline, " red ") ||
strstr(curline, " yellow "))) goto nextline;
                }

                for (columncount=0; (columncount<20); columncount++)
columns[columncount] = "";
                fsline = xstrdup(curline); columncount = 0; p =
strtok(fsline, " ");
                while (p && (columncount < 20)) { columns[columncount++]
= p; p = strtok(NULL, " "); }

So your dstype is not DT_NETAPP or DT_NETWARE or DT_AS400, the first
line have a "/", if the color is not "red" or "yellow" that line will be
treated as a data line and it will get some data from it and construct a
rrd file.

I had the same problem with netapp filers disk reporting of my script
when sending data with the /group option because the /group will be sent
to the rrd disk module (you'll not see it in the page but it's there
like the color) and in that case I started to have rrd file named with
HH:MM:SS ... I got the problem when i started to get 50-60 of those
files in each filers rrd file.

So it should be safe to skip the first line of the data reported by the
do_disk because it will not contain filesystems data (don't know if it
can create problem with netware or as400 but it works with
netapp/unix/windows clients at least).
