Can memcache tell you how much memory it is using?

Can memcac开发者_Go百科he tell you how much memory it is using in total?

How about for a particular key?

And on the command line, you could do this:

echo "stats" | nc 127.0.0.1 11211 | grep bytes

In php, but I'm sure you are able to translate to RoR:-

echo "You are using " . $memcache->getstats()["bytes"] . " of storage ";
echo "out of " . $memcache->getstats()["limit_maxbytes"];

See http://php.net/manual/en/memcache.getstats.php
