zabbix監(jiān)控nginx的狀態(tài)頁(yè)面

1.環(huán)境說明

主機(jī)名稱	IP地址	充當(dāng)角色	所需軟件
zabbbix	192.168.195.130	zabbix服務(wù)端	zabbix_server、zabbix_agent(需在lamp或lnmp上部署)
nginx	192.168.195.133	nginx、zabbix客戶端	nginx+zabbix_agent

2.所涉及到的知識(shí)點(diǎn)

1.安裝部署nginx請(qǐng)閱讀源碼編譯安裝部署lnmp

2.安裝部署zabbix服務(wù)端請(qǐng)閱讀監(jiān)控服務(wù)zabbix部署

3.配置郵箱告警和自定義監(jiān)控請(qǐng)閱讀zabbix服務(wù)配置郵箱告警（定義媒介、配置動(dòng)作和zabbix服務(wù)自定義監(jiān)控_碳烤小肥楊…的博客-CSDN博客

3.在nginx主機(jī)上安裝zabbix_agent

//通過zabbix主機(jī)將zabbix源碼包發(fā)送到nginx主機(jī)上

4.開啟nginx狀態(tài)顯示頁(yè)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，要放行本機(jī)和zabbix服務(wù)端   }//重啟服務(wù)后查看nginx狀態(tài)頁(yè)面
[root@nginx ~]# nginx -s stop 
[root@nginx ~]# nginx
[root@nginx ~]# curl http://192.168.195.133/status
Active connections: 1

主機(jī)上的配置完成

5.進(jìn)入zabbix的web頁(yè)面配置主機(jī)，監(jiān)控項(xiàng)，觸發(fā)器

5.1.添加主機(jī)

5.2.創(chuàng)建監(jiān)控項(xiàng)

5.3.創(chuàng)建觸發(fā)器

另外的writing數(shù)值和waiting數(shù)值與此相似，數(shù)值自己定義
