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
vimzabbix-agent/etc/zabbix_agentd.conf.d/userparameter_mysql.conf
UserParameter=mysql.repl[*],/storage/server/zabbix-agent/scripts/mysql_repl.py $1
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#/1/18 pdd
'''sys.argv[1] -> (/tmp/mysql3306.sock,/tmp/mysql3307.sock ...) 因为有多个mysql slave运行在mysqld_multi上'''

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
