You misunderstand. When using ranges, the given range are the limits
on the OK range, and anything outside that triggers the alert.

As per your explanation above, I would assume

-c 500000: -w 550000:

would be reasonable values. That will cause a critical alert when
the value is below 500000 and a warning value when it's below 550000.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
