zabbix で nginx 監視を設定する方法

vim /usr/local/nginx/conf/nginx.conf location /nginx_status { stub_status; } 说明： nginx_status 自定义字段，访问地址（例：192.168.169.131/nginx_status） stub_status 固定参数 # 重启 nginx ./nginx reload

浏览器访问状态说明： Active connections Nginx正处理的活动链接数个数；重要 server Nginx启动到现在共处理了多少个连接。 accepts Nginx启动到现在共成功创建几次握手。 handled requests Nginx总共处理了几次请求。 Reading Nginx读取到客户端的 Header 信息数。 Writing Nginx返回给客户端的 Header 信息数。 Waiting Nginx已经处理完正在等候下一次请求指令的驻留链接，开启。 Keep-alive的情况下，Waiting这个值等于active-（reading + writing）。 请求丢失数=(握手数-连接数)可以看出,本次状态显示没有丢失请求
