zabbix监控mysql
1、zabbix添加mysql的监控模板（template-app-mysql）之后，还需要在客户端添加key去取值。2、编写脚本，获取mysql的各种状态值。可以固定一个目录，专门存放监控脚本。比如/usr/local/zabbix/scripts/chk_mysql.sh
#!/bin/bash

#获取mysql版本
UserParameter=mysql.version,mysql -V
##获取mysql性能指标,这个是上面定义好的脚本
UserParameter=mysql.status[*],bash /alidata/zabbix-agentd/scripts/chk_mysql.sh $1
##获取mysql运行状态
UserParameter=mysql.ping,/alidata/mysql/bin/mysqladmin -uroot -pliujinWANG1985 -P3306 -h127.0.0.1ping | grep -c alive
UserParameter=mysql.process,/alidata/mysql/bin/mysql -uroot -pliujinWANG1985 -P3306 -h127.0.0.1-e "show processlist" 2>/dev/null|wc -l
4、重启zabbix的客户端
