I'll second this.  I came to Nagios from the BigBrother (BB) world.
BB's disk checks were based on utilitization, like df(1), so I tend to
think in terms of % used not % free.  I've found it very confusing
trying to switch to the % free methodology.

I guess that makes me a glass 1/2 full kind of person. :)
