zabbix监控nginx连接数

**一、nginx配置**

nginx 1.6，zabbix 4.0.5

利用nginx自己的监控模块对nginx连接数进行监控

nginx配置：

server {
        listen       80;
        server_name  127.0.0.1;
    
        error_page 500 502 503  /50x.html;
        location = /50x.html {
            root   /usr/local/nginx/html;
    
        }
    
        location /nginx_status {
              proxy_set_header X-Real-IP $remote_addr;
              proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
              stub_status on;
              access_log off;
              allow 127.0.0.1;
              allow 192.168.1.0/24;
              deny all;
        }
    
    }

**二、shell监控脚本**

新建脚本文件nginx\_status.sh ：

#!/bin/bash
    #zabbix监控nginx性能以及进程状态
    #
    
    
    HOST="127.0.0.1"
    PORT="80"
    
    # 检测nginx进程是否存在
    function ping {
        /sbin/pidof nginx | wc -l 
    }
    # 检测nginx性能
    function active {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
    }
    function reading {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'
    }
    function writing {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
    }
    function waiting {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
    }
    function accepts {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $1}'
    }
    function handled {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
    }
    function requests {
        /usr/bin/curl "http://$HOST:$PORT/nginx_status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
    }
    $1

**三、zabbix客户端配置**

1、修改配置

vi zabbix_agentd.conf 
    
    #添加以下配置项
    UserParameter=nginx.status[*],/home/data/scripts/nginx_status.sh $1

2、重启zabbix客户端

service zabbix-agent restart

3、zabbix服务端上测试是否能拿到客户端nginx监控数据

zabbix_get -s 192.168.1.11 -k 'nginx.status[active]'

**四、zabbix添加nginx主机配置**

1、导入监控模板

**nginx status详解**  
active connections – 活跃的连接数量  
server accepts handled requests — 总共处理了91835569个连接 , 成功创建91835569次握手, 总共处理了454138306个请求  
reading — 读取客户端的连接数.  
writing — 响应数据到客户端的数量  
waiting — 开启 keep-alive 的情况下,这个值等于 active – (reading+writing), 意思就是 Nginx 已经处理完正在等候下一次请求指令的驻留连接.
