You do eventually find out when the status turns purple.
This is a pretty hard one to deal with, from my experience. A hang on something NFS-related is pretty difficult to get out of. I've seen that mounting NFS with the "bg" option can improve this somewhat, but that might create other problems.

Hello,
I'm running a xymon-client on a Debian Jessie.
OS: Debian OS-Release: 8 (Jessie) xymon-client version : 4.3.17
The error happend due to a nfs ressource not responding. I suppose that as xymon launch "df" to get information and as the nfs was hanging, the xymon-client is no able to detect that the df hangs and it does not send any data to the server. Worst, the xymon-client is not verbose at all, it does not tell this test (df) takes too long to accomplish.
Many thanks for xymon.
Regards.
