zabbix自定义模板，邮件报警，代理服务器，自动发现与自动添加及snmp

//在客户端创建自定义 key
1.明确需要执行的 linux 命令
who | wc -l
 
2.创建 zabbix 的监控项配置文件，用于自定义 key
vim /etc/zabbix/zabbix_agent2.conf
#可以将自定义的监控项配置文件创建在 zabbix_agent2.d 目录中
268 Include=/etc/zabbix/zabbix_agent2.d/*.conf
#自定义监控项的格式如下
291 #	Format: UserParameter=,
 
cd /etc/zabbix/zabbix_agent2.d/
 
vim UserParameter_login.conf
UserParameter=login.user,who|wc -l
 
systemctl restart zabbix-agent2
 
3.在服务端验证新建的监控项
zabbix_get -s '192.168.73.114' -p 10050 -k 'login.user'

cd /etc/nginx/conf.d
vim default.conf
 
server {
...................
 location /nginx_status {
       stub_status on;
       access_log off;
       allow 127.0.0.1;
       allow 192.168.73.0/24;
       deny all;
...........................
}
