当运行dstat 监控mysql io 的时候报连接不到mysql server
[root@shylock ~]# dstat --mysql5-io Module dstat_mysql5_io failed to load. (Cannot interface with MySQL server) None of the stats you selected are available.
[root@shylock ~]# cd /usr/share/dstat [root@shylock dstat]# vi dstat_mysql5_io.py 3 global mysql_user 4 mysql_user = os.getenv(‘DSTAT_MYSQL_USER‘) or os.getenv(‘USER‘) 5 6 global mysql_pwd 7 mysql_pwd = os.getenv(‘DSTAT_MYSQL_PWD‘) 在/usr/shared/dstat目录下有dstat的命令和插件 vi dstat_mysql5_io.py 在3-7行里有声明mysql_user 和mysql_pwd os.getenv(环境变量名称) 从环境变量中获取MYSQL的用户名密码
#!/bin/bash #file:mysql5io.sh export DSTAT_MYSQL_USER=‘user‘ export DSTAT_MYSQL_PWD=‘pwd‘ dstat --mysql5-io $@
编写shell脚本 --"$@" 数组 "$*" 字符串
chmod 700 mysql5io.sh ./mysql5io.sh 3 5 #停3秒，获取5次结果

因为在脚本里 dstat --mysql5_io $@ 运行脚本传参数(参考dstat -h)
