nginx-vts-exporter：
资源下载：
wget https://github.com/hnlq715/nginx-vts-exporter/releases/download/v0.10.3/nginx-vts-exporter-0.10.3.linux-amd64.tar.gz
tar -zxvf nginx-vts-exporter-0.10.3.linux-amd64.tar.gznginx准备工作：
1,下载vts模块包
git clone https://github.com/vozlt/nginx-module-vts.git
2，移动到指定位置：
mv nginx-module-vts ~
3，进入nginx编译目录，重新编译（需要指定vts模块文件绝对目录）：
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-threads --with-file-aio --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_geoip_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_auth_request_module --with-http_random_index_module --with-http_secure_link_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module --with-mail --with-mail_ssl_module --with-stream --with-stream_ssl_module --with-stream_realip_module --with-stream_ssl_preread_module --with-stream_geoip_module --with-google_perftools_module --with-pcre --with-pcre-jit --with-luajit --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie' --add-module=/root/nginx-module-vts
二进制部署的nginx需要加入模块重新编译：--add-module=/root/nginx-module-vts
docker部署的nginx需要自定义重新编译nginx镜像，把模块编译进去，这里暂不做详细赘述，后续试验后补充2，部署操作
nginx添加配置
http新增配置：
vhost_traffic_status_zone;
#启用共享内存区域（shared memory zone），用于存储虚拟主机（server）、上游（upstream）、过滤器（filter）等的实时流量统计信息 #必须！！！！！
vhost_traffic_status_filter on;
#启用“过滤器”功能，允许你通过自定义标签（如 $server_name、$uri、$geoip_country_code 等变量）对流量进行分组统计。
新增server，vts专用
server {
listen 8080; #自定义
server_name 127.0.0.1; #只允许本地访问
location /status {
vhost_traffic_status_display;
vhost_traffic_status_display_format json; #json格式，给vts使用
access_log off;
allow 127.0.0.1;
deny all;
}
location / {
return 404;
}
}prometheus新增配置
- job_name: 'nginx-vts'
static_configs:
- targets: ['127.0.0.1:9913']
scrape_interval: 10s重启服务
systemctl daemon-reload
systemctl restart prometheus验证服务
浏览器访问promtheus
curl 127.0.0.1:9090
菜单路由：Status --> Targets
服务器访问nginx-vts-erporter
curl 127.0.0.1:9913/metrics
看到以下输出即可
#这里有一个点，通用的grafana的模板指标都是nginx_vts*，但是网上能看到的指标都是都是nginx_*，所以只能另想他法，可以导入常规监控模板，然后说的那个修改参数，也可以生成之后手动直接导入
登录grafana，导入下面的监控json模板
路径：左面菜单栏 --> dashboard --> 右面的新建 --> import --> 输入json，然后load即可
