Moxi, as part of it's support of memcached protocol, has support
for the memcached stats command. Regular
memcached clients can request statistics through the memcached
stats command. The stats command accepts optional arguments, and
in the case of Moxi, there is a stats proxy sub-command. A
detailed description of statistics available through Moxi can be
found
here.
For example, one simple client one may use is the commonly available netcat (output elided with ellipses):
$ echo "stats proxy" | nc localhost 11211 STAT basic:version 1.6.0 STAT basic:nthreads 5 … STAT proxy_main:conf_type dynamic STAT proxy_main:behavior:cycle 0 STAT proxy_main:behavior:downstream_max 4 STAT proxy_main:behavior:downstream_conn_max 0 STAT proxy_main:behavior:downstream_weight 0 … STAT proxy_main:stats:stat_configs 1 STAT proxy_main:stats:stat_config_fails 0 STAT proxy_main:stats:stat_proxy_starts 2 STAT proxy_main:stats:stat_proxy_start_fails 0 STAT proxy_main:stats:stat_proxy_existings 0 STAT proxy_main:stats:stat_proxy_shutdowns 0 STAT 11211:default:info:port 11211 STAT 11211:default:info:name default … STAT 11211:default:behavior:downstream_protocol 8 STAT 11211:default:behavior:downstream_timeout 0 STAT 11211:default:behavior:wait_queue_timeout 0 STAT 11211:default:behavior:time_stats 0 STAT 11211:default:behavior:connect_max_errors 0 STAT 11211:default:behavior:connect_retry_interval 0 STAT 11211:default:behavior:front_cache_max 200 STAT 11211:default:behavior:front_cache_lifespan 0 STAT 11211:default:behavior:front_cache_spec STAT 11211:default:behavior:front_cache_unspec STAT 11211:default:behavior:key_stats_max 4000 STAT 11211:default:behavior:key_stats_lifespan 0 STAT 11211:default:behavior:key_stats_spec STAT 11211:default:behavior:key_stats_unspec STAT 11211:default:behavior:optimize_set STAT 11211:default:behavior:usr default … STAT 11211:default:pstd_stats:num_upstream 1 STAT 11211:default:pstd_stats:tot_upstream 2 STAT 11211:default:pstd_stats:num_downstream_conn 1 STAT 11211:default:pstd_stats:tot_downstream_conn 1 STAT 11211:default:pstd_stats:tot_downstream_conn_acquired 1 STAT 11211:default:pstd_stats:tot_downstream_conn_released 1 STAT 11211:default:pstd_stats:tot_downstream_released 2 STAT 11211:default:pstd_stats:tot_downstream_reserved 1 STAT 11211:default:pstd_stats:tot_downstream_reserved_time 0 STAT 11211:default:pstd_stats:max_downstream_reserved_time 0 STAT 11211:default:pstd_stats:tot_downstream_freed 0 STAT 11211:default:pstd_stats:tot_downstream_quit_server 0 STAT 11211:default:pstd_stats:tot_downstream_max_reached 0 STAT 11211:default:pstd_stats:tot_downstream_create_failed 0 STAT 11211:default:pstd_stats:tot_downstream_connect 1 STAT 11211:default:pstd_stats:tot_downstream_connect_failed 0 STAT 11211:default:pstd_stats:tot_downstream_connect_timeout 0 STAT 11211:default:pstd_stats:tot_downstream_connect_interval 0 STAT 11211:default:pstd_stats:tot_downstream_connect_max_reached 0 … END
