Redis状态与性能监控命令

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 ======

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
