Zabbix监控mysql主从复制状态

原理

mysql slave

　　show slave status\G

　　在输出信息中查看I/O线程和SQL线程的状态值（YES为正常，NO为错误）

　　Slave_IO_Running: Yes

　　Slave_SQL_Running: Yes

配置

定义zabbix监控item key

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

UserParameter=mysql.repl[*],/storage/server/zabbix-agent/scripts/mysql_repl.py $

定义mysql slave监控账号

GRANT SUPER, REPLICATION CLIENT ON *.* TO 'zabbix_check'@'localhost' IDENTIFIED BY PASSWORD 'zabbix@check'

mysql_repl.py  # if Slave_IO_Running=Yes && Slave_SQL_Running=Yes print 1 else print 0

#!/usr/bin/python
# -*- coding: utf-8 -*-
# check mysql slave status
# 2016/1/18 pdd

测试

重启zabbix_agentd使监控key生效

客户端测试

服务器端　# 页面监控主机添加对应的application items
