1、获取 Nginx 状态（ HTTP Stub Status ）

/usr/local/nginx/sbin/nginx -V

2、配置 nginx.conf

vim /usr/local/nginx/conf/nginx.conf location ~ /nginx_status {       stub_status on;       access_log off;       allow 127.0.0.1;       allow 192.168.1.14;       deny all; }

3、编写脚本获取上面的 key 值

vim /script/nginx_status.sh #!/bin/bash case $1 in   active)     curl -s http://127.0.0.1/nginx_status | awk '/Active/ {print $3}' ;;   accepts)     curl -s http://127.0.0.1/nginx_status | awk 'NR==3 {print $1}' ;;   handled)     curl -s http://127.0.0.1/nginx_status | awk 'NR==3 {print $2}' ;;   requests)     curl -s http://127.0.0.1/nginx_status | awk 'NR==3 {print $3}' ;;   reading)     curl -s http://127.0.0.1/nginx_status | awk '/Reading/ {print $2}' ;;   writing)     curl -s http://127.0.0.1/nginx_status | awk '/Writing/ {print $4}' ;;   waiting)     curl -s http://127.0.0.1/nginx_status | awk '/Waiting/ {print $6}' ;;   *)     echo "Usage: $0 { active | accepts | handled | requests | reading | writing | waiting }" ;; esac chmod a+x /script/nginx_status.sh

4、添加自定义 key 配置文件

vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/nginx_status.conf # Nginx_status UserParameter=nginx.active,/script/nginx_status.sh active UserParameter=nginx.accepts,/script/nginx_status.sh accepts UserParameter=nginx.handled,/script/nginx_status.sh handled UserParameter=nginx.requests,/script/nginx_status.sh requests UserParameter=nginx.reading,/script/nginx_status.sh reading UserParameter=nginx.writing,/script/nginx_status.sh writing UserParameter=nginx.waiting,/script/nginx_status.sh waiting 5、修改zabbix_agentd.conf vim /usr/local/zabbix/etc/zabbix_agentd.conf LogFile=/tmp/zabbix_agentd.log Server=192.168.1.14 ServerActive=192.168.1.14 Hostname=Zabbix server Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/ EnableRemoteCommands=1 UnsafeUserParameters=1

6、Zabbix 服务端测试能否拿到 Key

/usr/local/zabbix/bin/zabbix_get -s 192.168.1.12 -k nginx.active




Nginx 监控项解释

Active connections: 1

server accepts handled requests

1 1 1

Reading: 0 Writing: 1 Waiting: 0

## Active connections: 对后端发起的活动连接数

## Server accepts handled requests: Nginx 总共处理了 1 个连接，成功创建了 1 次握手（没有失败次数），总共处理了 1 个请求

## 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 ), 意思是 Nginx 已经处理完成，正在等待下一次请求指令的驻留连接

## 在访问效率很高，请求很快被处理完毕的情况下，Waiting 数比较多是正常的。如果 reading + writing 数较多，则说明并发访问量很大，正在处理过程中
