Joerg,
Can you please subscribe to the list so you don't keep being rejected.
I think there's two things going on here:
1. The web interface is showing a different output because, I think,
you are not running check_disk remotely. All check commands run on
the Nagios server. You need NRPE / check_by_ssh / some other
mechanism to run check_disk on the monitored server.
2. The first set of output from head for /storage/media/video looks
correct (bar a rounding error - not sure why that would be true).
The /dev is completely wrong though. What OS are you using? Also, can
you run df --version to see which version of coreutils you are on.
