[Kurt Huwig]

Yeah, it it this line:

def free = output.find{ it =~ /avail free bytes/ }

This only works on English installations. A German installation will print

C:\npa\bin>fsutil volume diskfree d:
Gesamtanzahl an freien Bytes : 27177152512
Gesamtanzahl Bytes : 147819851776

[Chris Gilbert]

Thanks for your feedback Kurt. I'll see what I can do about making it work properly on other languages. Do you have issues with any of the other checks too, or just the disk space one - i.e. do cpu, memory and so on run correctly?

[Kurt Huwig]

It is just the disk check; the rest works fine, besides the HD temperature, but this might have other reasons.

[simon]

is there a solution for this problem?
