使用Zabbix4.4自定义模板监控 MySQL 性能

创建脚本

vim /etc/zabbix/zabbix_agentd.d/mysql_status.sh

#主机
HOST="localhost"
#用户
USER="root"
#密码
PASSWORD="123456"
#端口
PORT="3306"
#MySQL连接
CONNECTION="mysqladmin -h ${HOST} -u ${USER} -P ${PORT} -p${PASSWORD}"

if [ $# -ne "1" ];then
    echo "arg error!"
fi

case $1 in
    Uptime)
        result=`${CONNECTION} status 2>/dev/null |awk '{print $2}'`
        echo $result
        ;;
    Questions)
        result=`${CONNECTION} status 2>/dev/null |awk '{print $6}'`
        echo $result
        ;;
    Com_update)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_update" |awk '{print $4}'`
        echo $result
        ;;
    Slow_queries)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Slow_queries" |awk '{print $4}'`
        echo $result
        ;;
    Com_select)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_select" |awk '{print $4}'`
        echo $result
        ;;
    Com_rollback)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_rollback" |awk '{print $4}'`
        echo $result
        ;;
    Com_insert)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_insert" |awk '{print $4}'`
        echo $result
        ;;
    Com_delete)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_delete" |awk '{print $4}'`
        echo $result
        ;;
    Com_commit)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_commit" |awk '{print $4}'`
        echo $result
        ;;
    Bytes_sent)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Bytes_sent" |awk '{print $4}'`
        echo $result
        ;;
    Bytes_received)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Bytes_received" |awk '{print $4}'`
        echo $result
        ;;
    Com_begin)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_begin" |awk '{print $4}'`
        echo $result
        ;;*)
        echo "Usage:$0(Uptime|Questions|Com_update|Slow_queries|Com_select|Com_rollback|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)"
        ;;
esac

chmod +x /etc/zabbix/zabbix_agentd.d/mysql_status.sh #给脚本赋予执行权限

修改zabbix-agent配置文件，默认有一个MySQL的子配置文件，直接编辑该文件即可

vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

#获取MySQL性能指标，这个是上一步编辑好的脚本
UserParameter=mysql.status[*], /etc/zabbix/zabbix_agentd.d/mysql_status.sh $1
#获取MySQL运行状态
UserParameter=mysql.ping,mysqladmin -u root -h localhost -p123456 ping 2>/dev/null | grep -c alive
#获取MySQL版本
UserParameter=mysql.version,mysql -V

#重启 zabbix-agent
systemctl restart zabbix-agent

自定义模板

进入监控项

填写想要监控的键值和名称

添加后,创建图形

添加刚刚创建的监控项
