I’m sorry for asking a rookie question, but you seem to know memcached really well and I couldn’t find an answer online.

Is there a way to obtain/monitor the time stamp of LTU evictions?

I want to get a sense of how memory constrained my memcached server is, and it seems intuitive to me to monitor the “last used” date of recent evictions. Like, if The server is evicting values that haven’t been accessed in 3 months; great. But if the server is evicting values that were last used < 24 hours ago; I have concerns.

There are stats in "stats items" / "stats slabs". Last access time for most recent eviction per slab class, etc. (see doc/protocol.txt from the tarball).

"watch evictions" command will also show a stream of details for items being evicted.
