zabbix监控mysql

一、数据库给只读权限

1.1  grant usage on *.* to 'zabbix'@'127.0.0.1' identified by 'zabbix';
flush privileges;
1.2  mysql -uzabbix -pzabbix -h 127.0.0.1 -e "show global status"
Com_select从mysql启动以来接收的select语句的数量，它是一直往上增的。
Threads_connected获取的是一种当前的状态
1.3  mysql -uzabbix -pzabbix -h 127.0.0.1 -e "show global status"|grep 'Threads_connected'

二、zabbix监控mysql脚本（check_mysql.sh）

#!/bin/sh
while getopts "u:p:P:k:" opt
do
        case $opt in
                u ) user=$OPTARG;;
                p ) password=$OPTARG;;
                P ) port=$OPTARG;;
                k ) key=$OPTARG;;
                ? )
                echo 'parameter is wrong!'
                exit 1;;
        esac
done
if [ ! "${user}" ] || [ ! "${password}" ] || [ ! "${port}" ];then
        echo "parameter is null"        
        exit 1
fi

mysql -u ${user} -p${password} -h 127.0.0.1 -P${port} -e "show global status"|grep "${key}[[:space:]]"|awk '{print $2}'

三、zabbix自定义监控mysql的agent配置(vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/mysql.conf)

UserParameter=mysql.status[*],sh /usr/local/zabbix/check_mysql.sh -u zabbix -p zabbix -P $1 -k $2 2>/dev/null
配置完需要重启zabbix_agentd(pkill zabbix_agentd; sleep 3; /usr/local/zabbix/sbin/zabbix_agentd)

四、测试下看能否获取到值

zabbix_get -s 172.16.0.3 -k mysql.status[3306,Com_select]

五、网页上添加监控

net.tcp.service.perf[tcp,,3306]
mysql.status[3306,Threads_connected]
mysql.status[3306,Com_select]
mysql.status[3306,Com_update]
mysql.status[3306,Com_insert]
mysql.status[3306,Com_delete]

六、创建图形进行查看

七、触发器的增加

八、可设置成模板
