zabbix监控数据库

1. 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[]

2. 服务端命令行测试键值

[root@zabbix ~]# zabbix_get -s 172.16.1.51 -k mystat[Uptime]    
496

3. 编写脚本

[root@db01 log]# cat /server/scripts/chk_mysql.sh

4. 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

二, 判断端口是否存活,

1,方法:一:映射值:

0就是down 1就是up

2 ,方法不用值映射

创建触发器

三,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,要改客户端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

之前测试这样写成功启动myslq ,启动nginx就失败不知道怎么回事

visudo
## Same thing without a password
#%wheel ALL=(ALL)       NOPASSWD: ALL
zabbix  ALL=(ALL)       NOPASSWD: ALL

停止nginx,没有远程执行命令

[root@web01 ~]# systemctl stop nginx

查看日志

Jan 12 04:03:42 web01 sudo: pam_unix(sudo:auth): conversation failed
Jan 12 04:03:42 web01 sudo: pam_unix(sudo:auth): auth could not identify password for [zabbix]
Jan 12 04:03:42 web01 sudo: pam_succeed_if(sudo:auth): requirement "uid >= 1000" not met by user "zabbix"

后来改了visudo文件

[root@web01 ~]# visudo 
## Same thing without a password
#%wheel ALL=(ALL)       NOPASSWD: ALL
zabbix ALL=NOPASSWD: ALL

查看日志,远程支持命令成功

[root@web01 ~]# tail -f /var/log/secure
ticationAgent, locale en_US.UTF-8) (disconnected from bus)Jan 12 15:04:26 web01 sudo: zabbix : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/bin/systemctl restart nginx.service
