This is presumably just a munin issue, but pm-memcache-amo02 is not showing any GETs (and thus no hits).  According to the metrics we're getting from memcache in our app, this is not true.

pm-memcache-amo02: http://munin.mozilla.org/munin/app-memcache/pm-memcache-amo02.mozilla.org/memcached_rates.html

all memcache boxes: http://munin.mozilla.org/munin/app-memcache/comparison-week.html#memcache
munin's busted.

I think this is related to bug 565232. I just wanted to update that I am working on it, even though I haven't updated this bug in a while. Sorry for the delay.

I'm going to call this one closed. It started working again two days ago after what seems like the cache getting cleared on the box. Also, I will track general munin/memcache issues in bug 565232.
