Examples
The following example demonstrates how to obtain redis server statistics:
redis 127.0.0.1:6379> INFO # Server redis_version:2.8.13 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:c2238b38b1edb0e2 redis_mode:standalone os:Linux 3.5.0-48-generic x86_64 arch_bits:64 multiplexing_api:epoll gcc_version:4.7.2 process_id:3856 run_id:0e61abd297771de3fe812a3c21027732ac9f41fe tcp_port:6379 uptime_in_seconds:11554 uptime_in_days:0 hz:10 lru_clock:16651447 config_file: # Clients connected_clients:1 client-longest_output_list:0 client-biggest_input_buf:0 blocked_clients:0 # Memory used_memory:589016 used_memory_human:575.21K used_memory_rss:2461696 used_memory_peak:667312 used_memory_peak_human:651.67K used_memory_lua:33792 mem_fragmentation_ratio:4.18 mem_allocator:jemalloc-3.6.0 # Persistence loading:0 rdb_changes_since_last_save:3 rdb_bgsave_in_progress:0 rdb_last_save_time:1409158561 rdb_last_bgsave_status:ok rdb_last_bgsave_time_sec:0 rdb_current_bgsave_time_sec:-1 aof_enabled:0 aof_rewrite_in_progress:0 aof_rewrite_scheduled:0 aof_last_rewrite_time_sec:-1 aof_current_rewrite_time_sec:-1 aof_last_bgrewrite_status:ok aof_last_write_status:ok # Stats total_connections_received:24 total_commands_processed:294 instantaneous_ops_per_sec:0 rejected_connections:0 sync_full:0 sync_partial_ok:0 sync_partial_err:0 expired_keys:0 evicted_keys:0 keyspace_hits:41 keyspace_misses:82 pubsub_channels:0 pubsub_patterns:0 latest_fork_usec:264 # Replication role:master connected_slaves:0 master_repl_offset:0 repl_backlog_active:0 repl_backlog_size:1048576 repl_backlog_first_byte_offset:0 repl_backlog_histlen:0 # CPU used_cpu_sys:10.49 used_cpu_user:4.96 used_cpu_sys_children:0.00 used_cpu_user_children:0.01 # Keyspace db0:keys=94,expires=1,avg_ttl=41638810 db1:keys=1,expires=0,avg_ttl=0 db3:keys=1,expires=0,avg_ttl=0
