I have seen this before on that version. It seems to be caused by too long
status messages. Chech your hobbit test and see if it reports any status
messages that are too long. I fixed this problem by increasing the maximum
status message size (in hobbitserver.cfg). There are other discussions about
this on the mailing list.

All,

Please see below, there is a problem with disk monitoring on one of the
server. Can some one tell me if I did something wrong?

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.

Well, that looks good to me.  I have no idea.
