you just see the config of memcached. To see more you need admin tools, I use "phpMemcachedAdmin" for this. But with these tools you just see the detail status and config of memcached, the hitrates and the Slab details. If you know the size of the session data, you can look into the slab details and see the data there.
Cool! Thanks for the advice. I just set this up! Looks good. One question for you tho. In my about 1.9% of memcached used and 41.6% as 'wasted'. So I guess that means that my wiki setup isn't using that much of memcached. How can I determine the best size of the cache for my memcached setup? Currently I'm only using the default which is 64MB of cache.
Thanks, Tim

Hey guys,
Using the stats command to the memcached telnet interface, what am I looking for in the outuput to verify that sessions are indeed being stored in memcached?
Here's what I see in the output of that command:

What other stats are interesting to look at in relation to mediawiki and why?
Thanks,
