redis-benchmark

1.1 简介

第一个就介绍一下,Redis自带的性能检测工具redis-benchmark, 该工具可以模拟 N 个客户端同时发出 Y 个请求。 可以使用 redis-benchmark -h 来查看基准参数。

1.2 命令格式:

redis-benchmark [-h ] [-p ] [-c ] [-n <requests]> [-k ]

 

1.3 参数介绍:

序号选项描述默认值
1 -h 指定服务器主机名 127.0.0.1
2 -p 指定服务器端口 6379
3 -s 指定服务器 socket  
4 -c 指定并发连接数 50
5 -n 指定请求数 10000
6 -d 以字节的形式指定 SET/GET 值的数据大小 2
7 -k 1=keep alive 0=reconnect 1
8 -r SET/GET/INCR 使用随机 key, SADD 使用随机值  
9 -P 通过管道传输 <numreq> 请求 1
10 -q 强制退出 redis。仅显示 query/sec 值  
11 --csv 以 CSV 格式输出  
12 -l 生成循环,永久执行测试  
13 -t 仅运行以逗号分隔的测试命令列表。  
14 -I Idle 模式。仅打开 N 个 idle 连接并等待。  

1.4 实例:

1.4.1 同时执行1000个请求来检测性能:

[root@iZbp143t3oxhfc3ar7jey0Z data]# redis-benchmark -n 1000 -q

monitor

2.1 简介

查看redis的连接及读写操作

2.2 命令格式

2.3 实例:

 由于我现在的环境是集群,哨兵的情况下,看的更细一点,我这边就直接把视频里面的图占出来。

showlog

3.1 简介

redis的slowlog是redis用于记录记录慢查询执行时间的日志系统。由于slowlog只保存在内存中,因此slowlog的效率很高,完全不用担心会影响到redis的性能。Slowlog是Redis从2.2.12版本引入的一条命令。

3.2 命令格式

 命令

  • get :获取慢查询日志
  • len :获取慢查询日志条目数
  • reset :重置慢查询日志

在redis-cli中有关于slowlog的设置:

CONFIG SET slowlog-log-slower-than 6000   #设置慢查询的时间下线,单位:微妙

CONFIG SET slowlog-max-len 25  #设置慢查询命令对应的日志显示长度,单位:命令数 

现在流行的是Prometheus+Grafana搭建监控系统,页面炫酷,也可以监控redis
