Hi, and I guess you meant when an object is expired. Well, actually the only thing you can get from memcached regarding expired objects (AFAIK) is looking at the *reclaimed* variable of the memcached stats command. This variable was introduced in version 1.4.10 (IMO) and means " Number of times an entry was stored using memory from an expired entry" .
This is very limited and also doesn't tell anything about the number of objects that were expired and but were not reclaimed. There are bunch of other related stats you can look at using "stats slabs" (see more details here<https://github.com/memcached/memcached/blob/master/doc/protocol.txt>) but non of them really help you to understand the actual number of expired objects.
