Next, we can see the active counters that moxi tracks on a per-bucket basis. First, we can see that nothing's happened to the frontcache counters (unsurprisingly, as the frontcache feature has been configured off):

STAT 11211:default:stats:listening 2
STAT 11211:default:stats:listening_failed 0
STAT 11211:default:frontcache:max 0
STAT 11211:default:frontcache:oldest_live 0
STAT 11211:default:frontcache:tot_get_hits 0
STAT 11211:default:frontcache:tot_get_expires 0
STAT 11211:default:frontcache:tot_get_misses 0
STAT 11211:default:frontcache:tot_get_bytes 0
STAT 11211:default:frontcache:tot_adds 0
STAT 11211:default:frontcache:tot_add_skips 0
STAT 11211:default:frontcache:tot_add_fails 0
STAT 11211:default:frontcache:tot_add_bytes 0
STAT 11211:default:frontcache:tot_deletes 0
STAT 11211:default:frontcache:tot_evictions 0

Then, we can see more interesting and useful per-bucket statistics.

In general, counters named num_xxx are active counters (they increase and decrease). And, tot_xxx are counters that only increase (until there's a "stats proxy reset" command).

Below, "upstream" refers to client-side statistics (from your application). And "downstream" refers to Couchbase server-side statistics.

Of note, moxi acquires downstream connections from a connection pool, assigns them to upstream clients, and releases the downstream connections back into the connection when the upstream client has finished a request/response, if there were no errors (in which case moxi might close the downstream connection rather than releasing it back into the connection pool). Because of this, you'll see that "tot_downstream_conn_acquired" will often grow (hopefully, only slightly) faster than "tot_downstream_conn_released".

Of note in the previous section, if "tot_upstream_paused" grows much greater than "tot_upstream_unpaused", that means that client connections are stuck in a "paused" state, awaiting some event that wakes them up (such as moxi receiving a response from a Couchbase server or a reserved/assigned downstream connection getting closed).
