zabbix版本：V2.2
nginx版本：V1.8.0

一、Nginx基础活跃指标

图解一个客户端连接开源版本的Nginx情况：

n1.png

Accepts（接受）、Handled（已处理）、Requests（请求数）是一直在增加的计数器。Active（活跃）、Waiting（等待）、Reading（读）、Writing（写）随着请求量而增减。

NGINX worker 进程接受 OS 的连接请求时 Accepts 计数器增加，而Handled 是当实际的请求得到连接时（通过建立一个新的连接或重新使用一个空闲的）。这两个计数器的值通常都是相同的，如果它们有差别则表明连接被Dropped，往往这是由于资源限制，比如已经达到 NGINX 的worker_connections的限制。

一旦 NGINX 成功处理一个连接时，连接会移动到Active状态，在这里对客户端请求进行处理：

Active状态

Waiting: 活跃的连接也可以处于 Waiting 子状态，如果有在此刻没有活跃请求的话。新连接可以绕过这个状态并直接变为到 Reading 状态，最常见的是在使用“accept filter（接受过滤器）” 和 “deferred accept（延迟接受）”时，在这种情况下，NGINX 不会接收 worker 进程的通知，直到它具有足够的数据才开始响应。如果连接设置为 keep-alive ，那么它在发送响应后将处于等待状态。
Reading: 当接收到请求时，连接离开 Waiting 状态，并且该请求本身使 Reading 状态计数增加。在这种状态下 NGINX 会读取客户端请求首部。请求首部是比较小的，因此这通常是一个快速的操作。
Writing: 请求被读取之后，其使 Writing 状态计数增加，并保持在该状态，直到响应返回给客户端。这意味着，该请求在 Writing 状态时， 一方面 NGINX 等待来自上游系统的结果（系统放在 NGINX “后面”），另外一方面，NGINX 也在同时响应。请求往往会在 Writing 状态花费大量的时间。

通常，一个连接在同一时间只接受一个请求。在这种情况下，Active 连接的数目 == Waiting 的连接 + Reading 请求 + Writing 。

二、Nginx相关指标的收集

首先在nginx配置文件中打开stub_status功能，并通过nginx -s reload命令重新加载配置文件

vim /etc/nginx/nginx.conf

server {
    #zabbix监控nginx基本活跃指标
    location /ngx_status {
        stub_status on;
        access_log off;
        allow 127.0.0.1;
        deny all;
        }

nginx -s reload

通过curl命令，获取指标

curl http://127.0.0.1/ngx_status

Active connections: 1 
server accepts handled requests
 13791578 13791578 13796087 
Reading: 0 Writing: 1 Waiting: 0 

三、zabbix监控脚本

编辑的时候没有找到上传附件的地方，就直接将脚本和模板贴在下面了。

1.配置zabbix_agent.conf

vim /etc/zabbix/zabbix_agent.conf

UnsafeUserParameters=1
UserParameter=nginx.status[*],/opt/zabbix/ngx-status.sh $1

service zabbix-agent restart

2.配置ngx-status.sh

touch /opt/zabbix/ngx-status.sh
chown zabbix:zabbix /opt/zabbix/ngx-status.sh
chmow u+x /opt/zabbix/ngx-status.sh
vim /opt/zabbix/ngx-status.sh

#!/bin/bash

    echo $result

    echo $result

    echo $result
    ;;
    dropped)
    result=`/usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $1-$2}'`
    echo $result
    ;;
    *)
     echo "Usage:$0(ping|active|reading|writing|waiting|accepts|handled|requests|dropped)"
    ;;
esac

3.zabbix_web界面加载template

将ngx-statust_templates.xml导入zabbix里，再关联host即可
