一、基于`nginx-module-vts`监控

1.1 下载

https://github.com/vozlt/nginx-module-vts

1.2 重新编译nginx

./configure \
--prefix=/usr/local/nginx-1.25.0 \
--add-module=./nginx-module-vts-0.2.2   \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_stub_status_module  \
--with-http_gzip_static_module

1.3 nginx 配置

http {
    #---隐藏其他配置
    vhost_traffic_status_zone;
    vhost_traffic_status_filter_by_host on;
    server {
        #---隐藏其他的路由
        location /status {
            vhost_traffic_status_display;
            vhost_traffic_status_display_format html;
        }     
    }
}

1.4 Prometheus 配置

- job_name: "nginx_vts_status"
  metrics_path: '/status/format/prometheus'
  scrape_interval: 10s
  static_configs:
  - targets: ["192.168.1.201:88"]

1.5 配置 grafana

导入模板: https://grafana.com/grafana/dashboards/14824-nginx-vts-stats/

二、基于`nginx-prometheus-exporter`监控

2.1 配置nginx

确保当前运行的nginx支持http_stub_status
./nginx -V 2>&1 | grep -o with-http_stub_status_module

nginx 开启http_stub_status
vim /path2yournginx/nginx.conf

  server {
        listen   80;  
        location /nginx_status {
            stub_status on;
            access_log off;
            allow 127.0.0.1;
            deny all;
        }
}

2.2 配置`nginx-prometheus-exporter`

下载
https://github.com/nginxinc/nginx-prometheus-exporter
解压
tar -xzvf node_exporter-1.7.0.linux-amd64.tar.gz -C /usr/local/
运行
./nginx-prometheus-exporter -nginx.scrape-uri http://127.0.0.1/nginx_status

2.3 配置 Prometheus

- job_name: "nginx_status"
  metrics_path: '/metrics'
  scrape_interval: 10s
  static_configs:
  - targets: ["192.168.1.201:9113"]

2.4 导入模板
