在zabbix-agent端添加键值
-
vim /etc/zabbix/zabbix_agentd.d/mystat.conf
UserParameter=mystat[*],/server/scripts/chk_mysql.sh '$1' # 键值是mystat[]
服务端命令行测试键值
[root@zabbix ~]# zabbix_get -s 172.16.1.51 -k mystat[Uptime]
496
编写脚本
[root@db01 log]# cat /server/scripts/chk_mysql.sh
#!/bin/bash

web页面操作添加监控项
在对应的主机上创建监控项
创建1个监控项之后就点击克隆修改名称和键值
判断端口是否存活,
用值映射或不用值映射都行
创建触发器
还可以添加远程命令 mysql挂了重启,重启不成功,发送邮件
前提,要改2个配置文件
zabbix-agent配置文件中开启远程命令
EnableRemoteCommands=1
visudo 中添加zabbix用户免密
visudo
## Same thing without a password
#%wheel ALL=(ALL) NOPASSWD: ALL
zabbix ALL=(ALL) NOPASSWD: ALL
配置远程命令
