1、redis-benchmark
redis基准信息，redis服务器性能检测
redis-benchmark -h localhost -p 6379 -c 100 -n 100000
100个并发连接，100000个请求，检测host为localhost 端口为6379的redis服务器性能
[root@architect redis-1.2.6]# redis-benchmark -h localhost -p 6379 -c 100 -n 100000 ====== ping ====== 10001 requests completed in 0.41 seconds 50 parallel clients 3 bytes payload keep alive: 1 0.01% <= 0 milliseconds 23.09% <= 1 milliseconds 85.82% <= 2 milliseconds 95.60% <= 3 milliseconds 97.20% <= 4 milliseconds 97.96% <= 5 milliseconds 98.83% <= 6 milliseconds 99.41% <= 7 milliseconds 99.70% <= 8 milliseconds 99.99% <= 9 milliseconds 100.00% <= 12 milliseconds 24274.27 requests per second
2、redis-cli
redis-cli -h localhost -p 6380 monitor
dump all the received requests in real time;
监控host为localhost，端口为6380，redis的连接及读写操作
[root@architect redis-1.2.6]# redis-cli -h localhost -p 6380 monitor +ok +1289800615.808225 "monitor" +1289800615.839079 "get" "name" +1289800615.853694 "ping" +1289800615.853783 "ping" +1289800615.854646 "ping" +1289800615.854974 "ping" +1289800615.857693 "ping" +1289800615.866862 "ping" +1289800615.871944 "ping"
redis-cli -h localhost -p 6380 info
provide information and statistics about the server ;
提供host为localhost，端口为6380，redis服务的统计信息
[root@architect redis-1.2.6]# redis-cli -h localhost -p 6380 info redis_version:2.0.4 redis_git_sha1:00000000 redis_git_dirty:0 arch_bits:32 multiplexing_api:epoll process_id:21990 uptime_in_seconds:490580 uptime_in_days:5 connected_clients:103 connected_slaves:0 blocked_clients:0 used_memory:4453240 used_memory_human:4.25m changes_since_last_save:200 bgsave_in_progress:0 last_save_time:1290394640 bgrewriteaof_in_progress:0 total_connections_received:809 total_commands_processed:44094018 expired_keys:0 hash_max_zipmap_entries:64 hash_max_zipmap_value:512 pubsub_channels:0 pubsub_patterns:0 vm_enabled:0 role:slave master_host:localhost master_port:6379 master_link_status:up master_last_io_seconds_ago:18 db0:keys=1319,expires=0
3、redis-stat
redis-stat host localhost port 6380 overview
print general information about a redis instance;
实时打印出host为localhost，端口为6380，redis实例的总体信息
[root@architect redis-1.2.6]# redis-stat port 6380 overview ------- data ------ ------------ load ----------------------------- - childs - keys used-mem clients requests connections 1319 5.37m 103 44108021 (+44108021) 810 1319 5.38m 103 44108124 (+103) 810 1319 5.38m 103 44108225 (+101) 810 1319 5.39m 103 44108326 (+101) 810 1319 5.40m 103 44108427 (+101) 810 1319 5.41m 103 44108528 (+101) 810
redis-stat host localhost port 6380 overview
measure redis server latency;
输出host为localhost，端口为6380，redis服务中每个请求的响应时长
[root@architect redis-1.2.6]# redis-stat port 6380 latency 1: 0.16 ms 2: 0.11 ms 3: 0.15 ms 4: 0.11 ms 5: 0.18 ms 6: 0.14 ms
