nginx版本：V1.8.0
一、Nginx基礎(chǔ)活躍指標(biāo)
圖解一個(gè)客戶端連接開源版本的Nginx情況：
n1.png
Accepts（接受）笋除、Handled（已處理）浪汪、Requests（請求數(shù)）是一直在增加的計(jì)數(shù)器务冕。Active（活躍）竟贯、Waiting（等待）盗誊、Reading（讀）、Writing（寫）隨著請求量而增減士葫。
| 名稱 | 描述 | 指標(biāo)類型 |
|---|---|---|
| Accepts（接受） | NGINX 所接受的客戶端連接數(shù) | 資源: 功能 |
| Handled（已處理） | 成功的客戶端連接數(shù) | 資源: 功能 |
| Dropped（已丟棄乞而，計(jì)算得出） | 丟棄的連接數(shù)（接受 - 已處理） | 工作：錯(cuò)誤* |
| Requests（請求數(shù)） | 客戶端請求數(shù) | 工作：吞吐量 |
NGINX worker 進(jìn)程接受 OS 的連接請求時(shí) Accepts 計(jì)數(shù)器增加，而Handled 是當(dāng)實(shí)際的請求得到連接時(shí)（通過建立一個(gè)新的連接或重新使用一個(gè)空閑的）慢显。這兩個(gè)計(jì)數(shù)器的值通常都是相同的晦闰，如果它們有差別則表明連接被Dropped放祟，往往這是由于資源限制，比如已經(jīng)達(dá)到 NGINX 的worker_connections的限制呻右。
一旦 NGINX 成功處理一個(gè)連接時(shí)跪妥，連接會移動到Active狀態(tài)，在這里對客戶端請求進(jìn)行處理：
Active狀態(tài)
Waiting: 活躍的連接也可以處于 Waiting 子狀態(tài)声滥，如果有在此刻沒有活躍請求的話眉撵。新連接可以繞過這個(gè)狀態(tài)并直接變?yōu)榈?Reading 狀態(tài)，最常見的是在使用“accept filter（接受過濾器）” 和 “deferred accept（延遲接受）”時(shí)落塑，在這種情況下纽疟，NGINX 不會接收 worker 進(jìn)程的通知，直到它具有足夠的數(shù)據(jù)才開始響應(yīng)憾赁。如果連接設(shè)置為 keep-alive 污朽，那么它在發(fā)送響應(yīng)后將處于等待狀態(tài)。
Reading: 當(dāng)接收到請求時(shí)龙考，連接離開 Waiting 狀態(tài)蟆肆，并且該請求本身使 Reading 狀態(tài)計(jì)數(shù)增加。在這種狀態(tài)下 NGINX 會讀取客戶端請求首部晦款。請求首部是比較小的炎功，因此這通常是一個(gè)快速的操作。
Writing: 請求被讀取之后缓溅，其使 Writing 狀態(tài)計(jì)數(shù)增加蛇损，并保持在該狀態(tài)，直到響應(yīng)返回給客戶端坛怪。這意味著淤齐，該請求在 Writing 狀態(tài)時(shí)， 一方面 NGINX 等待來自上游系統(tǒng)的結(jié)果（系統(tǒng)放在 NGINX “后面”）袜匿，另外一方面更啄，NGINX 也在同時(shí)響應(yīng)。請求往往會在 Writing 狀態(tài)花費(fèi)大量的時(shí)間沉帮。
通常锈死，一個(gè)連接在同一時(shí)間只接受一個(gè)請求。在這種情況下穆壕，Active 連接的數(shù)目 == Waiting 的連接 + Reading 請求 + Writing 待牵。
二、Nginx相關(guān)指標(biāo)的收集
首先在nginx配置文件中打開stub_status功能喇勋，并通過nginx -s reload命令重新加載配置文件
vim /etc/nginx/nginx.conf
server {
#zabbix監(jiān)控nginx基本活躍指標(biāo)
location /ngx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
nginx -s reload
通過curl命令缨该，獲取指標(biāo)
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監(jiān)控腳本
編輯的時(shí)候沒有找到上傳附件的地方川背，就直接將腳本和模板貼在下面了贰拿。
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界面加載template
將ngx-statust_templates.xml導(dǎo)入zabbix里蛤袒，再關(guān)聯(lián)host即可
