如何监控innodbstatus指标-创新互联
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
help_info(){
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"
echo
}
