[xymon] Problem with disk monitoring

[Johan Sjöberg]

Are you using Xymon 4.3.0 beta?

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.
