prometheus监控nginx

 添加nginx-module-vts模块

# git clone https://github.com/vozlt/nginx-module-vts.git
# mv nginx-module-vts /usr/local/src

配置nginx

# wget http://nginx.org/download/nginx-1.20.2.tar.gz
# tar xvf nginx-1.20.2.tar.gz
# cd nginx-1.20.2/
# yum -y install openssl openssl-devel make zlib zlib-devel gcc gcc-c++ libtool pcre pcre-devel
# ./configure --prefix=/apps/nginx \
 --with-http_ssl_module \
 --with-http_v2_module \
 --with-http_realip_module \
 --with-http_stub_status_module \
 --with-http_gzip_static_module \
 --with-pcre \
 --with-file-aio \
 --with-stream \
 --with-stream_ssl_module \
 --with-stream_realip_module \
 --add-module=/usr/local/src/nginx-module-vts/
 
 # make
 # make install

添加nginx状态页

vim /apps/nginx/conf/nginx.conf
vhost_traffic_status_zone;

        location /status {
            vhost_traffic_status_display;
            vhost_traffic_status_display_format html;
        }

检测配置文件，没有问题直接启动

/apps/nginx/sbin/nginx -t
/apps/nginx/sbin/nginx

访问状态页

配置nginx-vts-exporter并启动，转换数据为key value格式

https://github.com/hnlq715/nginx-vts-exporter/releases/download/v0.10.3/nginx-vts-exporter-0.10.3.linux-amd64.tar.gz
cp nginx-vts-exporter-0.10.3.linux-amd64/nginx-vts-exporter /usr/local/bin/
nginx-vts-exporter -nginx.scrape_uri http://10.211.55.20/status/format/json

配置prometheus.yml 

  - job_name: "prometheus-nginx-metrics"
    static_configs:
      - targets: ["10.211.55.20:9913"]
