Cacti - nginx -

前期准备

探测nginx

#!/bin/bashhostname=$1result=`curl http://$hostname/nginx_status`echo $result

Active connections: 28500 server accepts handled requests 135478105597 135478105597 210542656774 Reading: 16175 Writing: 305 Waiting: 12020

提取有价值的信息

active connections -- 对后端发起的活动连接数server accepts handled requests -- nginx 总共处理了 16630948 个连接, 成功创建 16630948 次握手 (证明中间没有失败的), 总共处理了 31070465 个请求 (平均每次握手处理了 1.8个数据请求)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 -- 开启 keep-alive 的情况下，这个值等于 active - (reading + writing)，意思就是Nginx说已经处理完正在等候下一次请求指令的驻留连接

activeConnections -- 当前活跃,对后端发起的活动连接数handledTotal -- 启动后,一共处理了这么多,有成功的也有失败的handledSuccess  -- 启动后,一共处理了多少次成功的requestTotal -- 启动后,http request请求一共请求了多少次activeReading -- 当前活跃, 读取client发送的header 数目activeWriting -- 当前活跃, 返回给client的header 数目activeWaiting -- 当前活跃, client和server都在等待

说明下数据获取方式

• 只需要直接从server端获取就可以了
• 参数有两个,一个是ip地址,一个是type类型(类型我们直接放到data input method)里面

data input method

<path_cacti>/scripts/bigbig_nginx.sh <server_addr> activeConnections

data template

三个value放在一块更合适一些
