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|logicalphysical


#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

username=用户
passwd=密码


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