check_memcached and hits/misses

[Pär Åslund]

Hi,

We solved this with script.

But I'm a bit confused regarding what a misses threshold is suppose to tell me.
Contrary to hits/misses with fixed polling intervals that is stored to
compare previous run with current run. Which does catch a sudden
decrease in hits/misses ratio.

/p
