It appears that Xymon has slipped one field to the left in parsing the df
output. The string at the beginning of each of the lines before the actual
df ouput should be the name of the filesystem (plus an icon, but we'll
ignore that for now). Then it is using the available number as the percent
used, which, of course, is huge.

I don't know if this is causing the problem but there is some funkiness with
the first line of the df output. It is broken between the 10 and the 4 and
there is a ']' instead of an 'l' in the word "blocks". Maybe this is a
cut/paste error, but if not, it is certainly not right.

I think it should read something like

Filesystem          1K-blocks            Used   Available  Use%    Mounted
on

If your df actually outputs a broken first line I think that should be fixed
first, then see if Xymon parses the output correctly.
