hi,
there is a website which pageviews/day about 3M+,
and there are 1G x 6 memcached servers for caching role.
here is stat of one of the memcached server

i'm wondering is there a way(or standard) to measure that memcached server
in OVERLOAD or not?
if it's in OVERLOAD status. what can i do ? just add more memcached servers
and add more RAM usage?
any tips are appreciated. thank you all!!!
