I monitor filesystems on one of my xymon clients. This went really well until switching to NFS. I managed to list and monitor the NFS mount, but the parsing of the transmitted string for the disk usage seems to go wrong at some point
I would think that NFS-mounted filesystems would be monitored on the server that hosted them, rather than other servers that mount them.

Youve replaced "df -Pl" with "df -hP". The "-h" changes the headers. This is important because the [df] parser specifically looks for columns with the titles "Available", "Capacity" and "Mounted" to work out what each column is for. By adding "-h" you instead get "Avail", "Use%" and "Mounted". I think when the column headers cant be found, the parser will assume that the values are in position 1, hence the "172" being interpreted as disk space usage.
Try changing "df -hP" to "df -P" and see if that works better.
