mysql> show slave status \G

Slave_IO_Running: Yes
Slave_SQL_Running: Yes
|
主从正常的情况是
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
现在使用命令语句获取主从状态YES的值:
|
1
2
|
[root@data]
# echo "show slave status \G"|/usr/local/mysql/bin/mysql -uzabbix 2>/dev/null|grep -E "Slave_IO_Running|Slave_SQL_Running"|awk '{print $2}'|grep -c Yes
2
|
值为2说明状态正常,如果为0或者1,主从复制不正常,这个时候zabbix应该报警.

在zabbix服务器控制端创建一个Template模板:
选择"Configuration"-"Template",然后点击"Create template",
名称为:Template App MySQL Replication
创建Items,
Name:MySQL slave status
Type:Zabbix agent (active)
Key:mysql.replication
创建Triggers
Name:MySQL Replication error on {HOST.NAME}
Expression:{Template App MySQL Replication:mysql.replication.last()}<2
模板创建好之后,将模板Link到要监控的主机.最终的监控状态如下
其中有一段时间内Mysql 主从失败,zabbix会发出报警.
