Running df -P | grep USB manually results in? the following results, with quite a bit of space between the output sections. /dev/sda?????????????????? 960303848? 268800 911180536?????? 1% /media/user/USB-1TB
Putting df -P | grep USB into the script results in the Server page showing the 'Expected strings (Capacity and Mounted) not found' error

Hi Kris,
in analysis.cfg you can only set thresholds for disks which are reported by the client and thus are already visible in the disk and inode column of your Xymon server. If there is no USB drive and no graph, then you don't need to mess up with server side config. By default the Xymon client will only provide info about local disks (which makes sense, as the remote mounted disks should be monitored at the source and not at dozens of connected servers), and also only for fixed mounted disks to avoid alerts if a removable media gets disconnected. If you want to change this you have to modify the linux client script (but as pointed out, ensure the output as Posix standard to not confuse the server side evaluation!). So it is no problem to remove the "l" from "df -Pl", but not the "P". You can also remove the "-x $EXCLUDES" w/o problems. Does a "df -P | grep USB" show your USB drive? If yes, modify the client script and test by "./xymonclient-linux.sh | grep USB". This also should show your USB drive. If not, the disk is not properly mounted.

Continued thanks for the responses.? I did try commenting everything out of the analysis.cfg except for the default DISK * line, but still no joy.? I don't think analysis.cfg is causing the USB to be ignored.? The xymonclient-linux script has been set back to it's original state.
