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: 10.01% <= 0 milliseconds23.09% <= 1 milliseconds85.82% <= 2 milliseconds95.60% <= 3 milliseconds97.20% <= 4 milliseconds97.96% <= 5 milliseconds98.83% <= 6 milliseconds99.41% <= 7 milliseconds99.70% <= 8 milliseconds99.99% <= 9 milliseconds100.00% <= 12 milliseconds24274.27 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"#p#分页标题#e#


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

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 ([phone]         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        #p#分页标题#e#


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 latency1: 0.16 ms2: 0.11 ms3: 0.15 ms4: 0.11 ms5: 0.18 ms6: 0.14 ms
