Once your cache fills up, you can use the "stats" command. Look at the 
ratio between the "bytes" stat (the total amount of memory actually in 
use) and the "limit_maxbytes" stat (the total amount of memory allocated 
once the cache is full.)

That works in both 1.1.x and 1.2.x.

It's also possible to figure out the ratio when the cache isn't full, 
but that's more complicated; you have to use "stats slabs" and subtract 
out the space that hasn't been used yet in each slab.
