It is possible that your problem stems from the fact that /tmp is type "none" and that a grep looking for /dev would fail. I'm not exactly sure what Xymon looks for, but I had to manually change some scripts associated with BB to look for even ZFS filesystems which do not have devices under / (or at least they don't appear to from df's POV).
Precisely. The "df" data does not have info about /tmp, so you need to look at the Xymon client script running on the server to have it report data for non-physical filesystems. Look at the ~xymon/client/bin/xymonclient-OSNAME.sh script (or "hobbit" ditto). By default, non-physical filesystems are excluded.
