prometheus监控nginx的实现

解压
unzip nginx-module-vts-master.zip
mv nginx-module-vts-master /usr/local/

tar zxvf nginx-1.15.7.tar.gz
cd nginx-1.15.7

./configure  --prefix=/usr/local/nginx --with-http_gzip_static_module --with-http_stub_status_module --with-http_ssl_module --with-pcre --with-file-aio --with-http_realip_module --add-module=/usr/local/nginx-module-vts-master

make && make install

vim /usr/local/nginx/conf/nginx.conf

server下添加如下：http {
    vhost_traffic_status_zone;  --添加

    ...

    server {

        ...

        location /status {
            vhost_traffic_status_display;  --添加
            vhost_traffic_status_display_fORMat html;  --添加
        }
    }
}

tar -zxvf nginx-vts-exporter-0.9.1.linux-amd64.tar.gz
 mv nginx-vts-exporter-0.9.1.linux-amd64  /usr/local/nginx-vts-exporter
chmod +x /usr/local/nginx-vts-exporter-0.5/bin/nginx-vts-exporter
cd /usr/local/nginx-vts-exporter/bin
通过nginx-vts-exporter二进制文件来执行nginx-vts-exporter程序
nohup ./nginx-vts-exporter  -nginx.scrape_uri http://10.10.xx.xx:80/status/format/json &

#注意：http://10.10.xx.xx/status/format/json这个地方的ip地址是nginx的IP地址
nginx-vts-exporter的监听端口是9913
