Question

我在分开的容器中都有prometheus，nginx-vts，php和nginx-vts-exporter，我正试图从导出器获取prometheus的指标，它一直告诉我Get http://127.0.0.1:9913/metrics：拨打tcp 127.0 .0.1：9913：连接：连接被拒绝

当我启动docker-compose文件时，出现此错误
2019/03/01 17:42:55 fetchHTTP失败获取http://localhost/status/format/json：拨打tcp 127.0.0.1:80：getsockopt：连接被拒绝

这是我的nginx.con文件

server
{
listen   80;
server_name localhost.x.com;

root /var/www/html/x.com;
index index.php index.html index.htm;




location /
{
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
}

location ~ \.php$ {
    fastcgi_pass   test-php:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
}



    location /status {
        vhost_traffic_status_display;
        vhost_traffic_status_bypass_stats on;
        vhost_traffic_status_display_format html;
        allow all;


    }


}

这是我的docker-compose文件

version: '3'
services:
  php:
    container_name: php
    image: php:fpm
    volumes:
      - ./code:/var/www/html/x


  nginx:
    container_name: Nginx
    image: arquivei/nginx-vts:latest
    volumes:
      - ./code:/var/www/html/x.com
      - ./site.conf:/etc/nginx/conf.d/x.conf:ro
    ports:
      - 80:80
    links: 
     - nginx-vts-exporter

  prom:
    container_name: Prometheus
    image: prom/prometheus:latest
    volumes: 
     - ./monitor/prometheus.yml:/etc/prometheus/prometheus.yml
    ports:
     - 9090:9090




  nginx-vts-exporter:
    container_name:  Exporter
    image: sophos/nginx-vts-exporter:latest
    ports:        
     - 9913:9913

这是我的prometheus.yml

  global:
    scrape_interval: 15s
    evaluation_interval: 15s
scrape_configs:
 - job_name: nginx
   static_configs:
    - targets: ['127.0.0.1:9913']

 - job_name: prometheus
   static_configs:
    - targets: ['127.0.0.1:9090']

Answer 1

在prometheus.yml文件中，应使用nginx-vts-exporter:9913而不是127.0.0.1:9913作为nginx导出程序的目标。与prometheus目标相同。不要使用127.0.0.1，而是使用容器的名称。

此外，您似乎需要配置nginx导出器以刮除nginx:80而不是localhost来检索状态信息。您可以通过将docker-compose文件中NGINX_HOST容器的环境变量http://nging/status/format/json设置为nginx-vts-exporter来做到这一点，就像这样：

  nginx-vts-exporter:
      container_name:  Exporter
      image: sophos/nginx-vts-exporter:latest
      environment:
        - NGINX_HOST="http://nging/status/format/json"       
      ports:        
       - 9913:9913

Nginx VTS出口商连接被拒绝
