如何监控innodb status指标

这篇文章主要介绍如何监控innodb status指标，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

输入被监控机器的ip 实时获取innodb相关status指标，包含：
---------|--- MySQL Command Status --|----- Innodb row operation ----|-- Buffer Pool Read --
---QPS---|select insert update delete|  read inserted updated deleted|   logical    physical


#需要编译脚本 写入账号密码  
#可以给自己维护的所有DB创建一个监控专用账号 密码统一 这样写死在脚本中 直接用即可
]$ cat innodb_status.sh 
#!/bin/bash


#参数变量
host=$1
port=$2
username=用户
passwd=密码


#echo "sh $0 $host $username $passwd $port"


#fountion 脚本说明、帮助

    echo "NAME"  
    echo "      $0"  
    echo "SYNOPSIS"  
    echo "      $0 is a shell script and monitor innodb status,eg:qps,tps......"  
    echo "DESCRIPTION"  
    echo "      option like mysql client -h host -u username -p password -P port"  
    echo "Usage:"
    echo "      sh $0 ipaddr username password port"
    echo "      E.g sh $0 10.111.7.31 3306 yujx yujxpw"
