zabbix服务--mysql（一）主从监控

基于搭建mysql主从，在客户端操作

1，创建监控mysql主从状态脚本，并创建授权用户

[root@localhost ~] cd /etc/zabbix/scripts/
[root@localhost scripts] vim check_mysql.sh
[root@localhost scripts] cat check_mysql.sh 
#!/bin/bash
case $1 in 
	slave_status)
	mysql -ucheck -p123 -e "show slave status \G"|grep "Running"|grep "Yes"|awk '{print $2}'|wc -l
	;;
esac

#在slave库创建授权用户
MariaDB [(none)]> grant all on *.* to 'check'@'localhost' identified by '123';
MariaDB [(none)]> flush privileges;

2，编辑客户端配置文件，并重启

[root@localhost scripts] cd /etc/zabbix/zabbix_agentd.d/
[root@localhost zabbix_agentd.d] vim check_mysql.conf 

[root@localhost zabbix_agentd.d] cat check_mysql.conf 
UserParameter=mysql_status[*],/etc/zabbix/scripts/check_mysql.sh $1

[root@localhost zabbix_agentd.d] systemctl restart zabbix-agent

3，在服务端测试

[root@localhost ~] zabbix_get -s 192.168.59.112 -k mysql_status[slave_status]
2
#返回值为2，是正常状态

4，在web端设置监控







5，宕掉slave，会触发报警

6，添加图形



二，流量监控
1，过滤出监控内容，并写进脚本

[root@localhost scripts] mysqladmin extended-status |grep "Bytes_sent"|awk '{print $4}'
3969067
[root@localhost scripts] mysqladmin extended-status |grep "Bytes_received"|awk '{print $4}'
8960924

[root@localhost scripts] vim check_mysql.sh 
[root@localhost scripts] cat check_mysql.sh 
#!/bin/bash
case $1 in 
	slave_status)
	mysql -ucheck -p123 -e "show slave status \G"|grep "Running"|grep "Yes"|awk '{print $2}'|wc -l
	;;
	Bytes_sent) #发送流量
	mysqladmin extended-status |grep "Bytes_sent"|awk '{print $4}'
	;;
	Bytes_received)	#接受流量
	mysqladmin extended-status |grep "Bytes_received"|awk '{print $4}'
	;;
esac

2，在服务端设置监控






三，监控增删改查
1，将监控项写进脚本

[root@localhost scripts] vim check_mysql.sh 
[root@localhost scripts] cat check_mysql.sh 
#!/bin/bash
case $1 in 
	slave_status)
	mysql -ucheck -p123 -e "show slave status \G"|grep "Running"|grep "Yes"|awk '{print $2}'|wc -l
	;;
	Bytes_sent) #发送流量
	mysqladmin extended-status |grep "Bytes_sent"|awk '{print $4}'
	;;
	Bytes_received)	#接受流量
	mysqladmin extended-status |grep "Bytes_received"|awk '{print $4}'
	;;
	Com_insert) #增加插入数据
	mysqladmin extended-status |grep -w "Com_insert"|awk '{print $4}'
	;;
Com_delete) #删除数据
mysqladmin extended-status |grep -w "Com_delete"|awk '{print $4}'
;;
Com_update) #修改数据
mysqladmin extended-status |grep -w "Com_update"|awk '{print $4}'
;;
Com_select) #查看数据
mysqladmin extended-status |grep -w "Com_select"|awk '{print $4}'
;;
Com_commit) #数据回滚
mysqladmin extended-status |grep -w "Com_commit"|awk '{print $4}'
;;
Com_rollback) #数据提交
mysqladmin extended-status |grep -w "Com_rollback"|awk '{print $4}'
;;
esac

2，在服务端设置
