I added them to the release notes (and they've been documented in
full context in protocol.txt). I'm pretty sure that was all of them.
If I missed something, please let me know.
1.3.1 New Stats
----------------
* Delete
The global stats now contain statistics on deletion.
delete_hits refers to the number of times a deletion command was
issued which resulted in a modification of the cache while
delete_misses refers to the number of times a deletion command was
issued which had no effect due to a key mismatch.
* Incr/Decr
Incr and decr each have a pair of stats showing when a
successful/unsuccessful incr occurred. incr_hits, incr_misses,
decr_hits, and decr_misses show where such mutations worked and
where
they failed to find an existing object to mutate.
* CAS
CAS stats are tracked in three different ways:
+ cas_hits
Number of attempts to CAS in a new value that worked.
+ cas_misses
Number of attempts to CAS in a value where the key was not found.
+ cas_badval
Number of attempts to CAS in a value where the CAS failed due to
the
object changing between the gets and the update.
* slab class evicted time
Per slab class, you can now see how recently accessed the most
recent
evicted data was. This is a useful gauge to determine eviction
velocity on a slab so you can know whether evictions are healthy or
if
you've got a problem.
1.3.2 More Granular Stats
--------------------------
Where possible, stats are now tracked individually by slab class. The
following stats are available on a per-slab-class basis (via "stats
slabs"):
* get_hits
* cmd_set
* delete_hits
* incr_hits
* decr_hits
* cas_hits
* cas_badval
(misses are obviously not available as they refer to a non-existent
item)
1.3.3 Removed stats
--------------------
"stats malloc" and "stats maps" have been removed.
If you depended on these commands for anything, please let us know so
we can bring them back in a more maintainable way.
