zabbix监控nginx的状态页面

1.环境说明

主机名称	IP地址	充当角色	所需软件
zabbbix	192.168.195.130	zabbix服务端	zabbix_server、zabbix_agent(需在lamp或lnmp上部署)
nginx	192.168.195.133	nginx、zabbix客户端	nginx+zabbix_agent

2.所涉及到的知识点

1.安装部署nginx请阅读源码编译安装部署lnmp

2.安装部署zabbix服务端请阅读监控服务zabbix部署

3.配置邮箱告警和自定义监控请阅读zabbix服务配置邮箱告警（定义媒介、配置动作和zabbix服务自定义监控_碳烤小肥杨…的博客-CSDN博客

3.在nginx主机上安装zabbix_agent

//通过zabbix主机将zabbix源码包发送到nginx主机上

最后报这个则表示编译成功，可直接使用make install安装[root@nginx zabbix-6.4.6]# make install//修改zabbix客户端的配置文件

4.开启nginx状态显示页面

[root@nginx ~]# vim /usr/local/nginx/conf/nginx.conf
[root@nginx ~]# cat /usr/local/nginx/conf/nginx.conf
......
location /status {stub_status on;allow 192.168.195.0/24;       //放行的ip，要放行本机和zabbix服务端   }//重启服务后查看nginx状态页面
[root@nginx ~]# nginx -s stop 
[root@nginx ~]# nginx
[root@nginx ~]# curl http://192.168.195.133/status
Active connections: 1 
server accepts handled requests1 1 1 
Reading: 0 Writing: 1 Waiting: 0//为监控nginx状态编写脚本文件
[root@nginx ~]# mkdir /scripts && cd /scripts
[root@nginx scripts]# vim nginx_status.sh
[root@nginx scripts]# chmod +x nginx_status.sh
[root@nginx scripts]# cat nginx_status.sh 
#!/bin/bashif [ $1 == 'reading' ]; thencurl -s 192.168.195.133/status | awk 'NR==4{print $2}'elif [ $1 == 'writing' ]; thencurl -s 192.168.195.133/status | awk 'NR==4{print $4}'elif [ $1 == 'waiting' ]; thencurl -s 192.168.195.133/status | awk 'NR==4{print $6}'
fi
[root@nginx scripts]# //进入配置文件，创建自定义监控任务
[root@nginx ~]# vim /usr/local/etc/zabbix_agentd.conf
[root@nginx ~]# tail -1 /usr/local/etc/zabbix_agentd.conf
UserParameter=check_nginx[*],/scripts/nginx_status.sh $1//因为我们修改了配置文件，所以需要重启服务，重新读取配置文件内容
[root@nginx ~]# systemctl restart zabbix_agentd.service//创建自定义监控任务后，我们需要在server端去测试一下是否能接受到被监控端的值
[root@zabbix ~]# zabbix_get -s 192.168.195.133 -k check_nginx['reading']
0
[root@zabbix ~]# zabbix_get -s 192.168.195.133 -k check_nginx['writing']
1
[root@zabbix ~]# zabbix_get -s 192.168.195.133 -k check_nginx['waiting']
0
[root@zabbix ~]#            //成功接收到值

主机上的配置完成

5.进入zabbix的web页面配置主机，监控项，触发器

5.1.添加主机

5.2.创建监控项

5.3.创建触发器

另外的writing数值和waiting数值与此相似，数值自己定义
