Hobbit client data parsing

[Arnoud Post]

I use Hobbit client and server, but the data was not parsed propperly. This
happend 2 times now.

The disk check gives this error:
 - Filesystems NOT ok
red Expected string (Capacity and Mounted) not found in df output header

And after that the disk graphs are split up because there are 2 extra diskslices
added:
"/status"
"//dev/ad0s1b"
According to the graph the counters for these slices are "nan" instead of 0.0 or
any other number.

Does anybody have familiar problems?

Henrik, is there a smart way to make a copy of the clientdata file if there are
any alerts (red or yellow)?
