Hi,
I'm running memcached-1.4.14 in CentOS 6 x86_64 system, and my clients
write small objects in memcached. I'm staring memcached with this
directives:
memcached -d -p 11211 -u memcache -m 18432 -c 12288 -P
/var/run/memcached/memcached.pid -t 64
The memory has enough space, the slabs are not
free_chunks_end is just a counter for how many chunks are available in a
recently allocated slab page. So if a slab class grabs 1MB of new memory,
it'll have something in free_chunks_end temporarily, then it all moves
into free_chunks or otherwise gets used.
In 1.4.15 this counter is gone complete
Dormando,
Thank you for your reply!
I understood your explanation. But I installed 1.4.15 version in a test
server (not production) and the behaviour is the same:
# Item_Size Max_age Pages Count Full? Evicted Evict_Time OOM
2 224B59s 1 2 yes0
Maybe I forgot to remove the stat.
Again, you're not doing anything wrong. free_chunks_end is just a weird
indicator.
free_chunks == free_chunks + free_chunks_end. that's all.

Actually I think I made that change in 1.4.14, not 1.4.15. but whatever :P
I'll remove the stat for the next cut, sorry!

No problem! :)
But, without free_chunks_end indicator, what about the column "Full?" of
memcached-tool?

I think that's just misleading.
It means the slab is in full use... memcached can't actually tell if a
slab class is full or not. you measure that by eviction rate evicted_time,
evicted_nonfetched, etc. there's some discussion at the wiki.

Perfect.
One more time, thank you Dormando!
