关于redis状态监控和性能调优详解
前言
对于任何应用服务和组件，都需要一套完善可靠谱监控方案。
尤其redis这类敏感的纯内存、高并发和低延时的服务，一套完善的监控告警方案，是精细化运营的前提。
本文主要给大家介绍了关于redis状态监控和性能调优的相关内容，分享出来供大家参考学习，下面话不多说了，来一起看看详细的介绍吧。
1、redis-benchmark
redis基准信息，redis服务器性能检测
例如：
检测redis服务器性能，本机6379端口的实例，100个并发连接，100000个请求
redis-benchmark-hlocalhost-p6379-c100-n100000

2、redis-cli
例1：监控本机6379端口的实例的数据操作，redis的连接及读写操作
redis-cli-hlocalhost-p6379monitor
先开启一个终端1，用于redis监控
[root@redis-server~]#redis-cli-hlocalhost-p6379monitor OK 1504689350.635365[0127.0.0.1:57996]"COMMAND" 1504689361.944610[0127.0.0.1:57996]"set""a""1" 1504689369.782029[0127.0.0.1:57996]"get""a"
然后在开启一个redis终端2进行操作
[root@redis-server~]#redis-cli-p6379 127.0.0.1:6380>seta1 OK 127.0.0.1:6380>geta "1" 127.0.0.1:6380>
可以看到终端2上面进行的数据操作会在终端1上面被记录下来
例2：查询本机redis实例的信息，端口6379
redis-cli-hlocalhost-p6379info
备注：该命令也可以在redis终端里面进行查询
[root@redis-server~]#redis-cli-hlocalhost-p6379info #Server redis_version:3.2.10 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:eae5a0b8746eb6ce redis_mode:standalone os:Linux2.6.32-431.el6.x86_64x86_64 arch_bits:64 multiplexing_api:epoll gcc_version:4.4.7 process_id:6003 run_id:0057d03b2e908ee036c2aa1c3531e8aa051d7468 tcp_port:6379 uptime_in_seconds:159221 uptime_in_days:1 hz:10 lru_clock:11517636 executable:/usr/local/redis/bin/redis-server config_file:/usr/local/redis/conf/redis.conf #Clients connected_clients:1 client_longest_output_list:0 client_biggest_input_buf:0 blocked_clients:0 #Memory used_memory:1828104 used_memory_human:1.74M used_memory_rss:4050944 used_memory_rss_human:3.86M used_memory_peak:8439360 used_memory_peak_human:8.05M total_system_memory:1960443904 total_system_memory_human:1.83G used_memory_lua:37888 used_memory_lua_human:37.00K maxmemory:0 maxmemory_human:0B maxmemory_policy:noeviction mem_fragmentation_ratio:2.22 mem_allocator:jemalloc-4.0.3 #Persistence loading:0 rdb_changes_since_last_save:0 rdb_bgsave_in_progress:0 rdb_last_save_time:1504689256 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:3603 total_commands_processed:3600007 instantaneous_ops_per_sec:0 total_net_input_bytes:192800186 total_net_output_bytes:2634476722 instantaneous_input_kbps:0.00 instantaneous_output_kbps:0.00 rejected_connections:0 sync_full:0 sync_partial_ok:0 sync_partial_err:0 expired_keys:0 evicted_keys:0 keyspace_hits:1000003 keyspace_misses:0 pubsub_channels:0 pubsub_patterns:0 latest_fork_usec:408 migrate_cached_sockets:0 #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:99.45 used_cpu_user:108.88 used_cpu_sys_children:0.01 used_cpu_user_children:0.01 #Cluster cluster_enabled:0 #Keyspace db0:keys=7,expires=0,avg_ttl=0 [root@redis-server~]#
