Hi.

This is from the old / soon to be disabled again Nagios Plugins bug tracker that used to be at Nagios itself.
I've just copied this bug over. I'm not the original reporter and have no idea about the thoughts about this bug.

Hello

I use CentOS release 5.6 (Final) 64 bits, with:
check_disk v1.4.15 (nagios-plugins 1.4.15)

When i use:

check_disk -u bytes -w 20% -c 10%

Please NOTE -u bytes

return invalid performance data (negative values):
