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。
| 名称 | 描述 | 指标类型 |
|---|---|---|
| Accepts（接受） | NGINX 所接受的客户端连接数 | 资源: 功能 |
| Handled（已处理） | 成功的客户端连接数 | 资源: 功能 |
| Dropped（已丢弃，计算得出） | 丢弃的连接数（接受 - 已处理） | 工作：错误* |
| Requests（请求数） | 客户端请求数 | 工作：吞吐量 |
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

3.zabbix_web界面加载template
将ngx-statust_templates.xml导入zabbix里，再关联host即可
