18 nginx 监控 一篇就够

wget <u>https://github.com/hnlq715/nginx-vts-exporter/releases/download/v0.10.3/nginx-vts-exporter-0.10.3.linux-amd64.tar.gz</u>

给已经运行的Nginx安装nginx-module-vts模块

下载nginx-module-vts

解压重新配置****configure

./configure ${上面 nginx -V 显示出来的编译参数，原样的放在这里} --add-module=/home/monitor/nginx-module-vts

make 但不要install，否则就会把正在运行的覆盖了

备份并替换启动文件nginx

cp /home/software/nginx/sbin/nginx /home/software/nginx/sbin/nginx-bak

cp /home/software/nginx-1.16.1/objs/nginx /home/software/nginx/sbin/nginx

添加监控模块

vhost_traffic_status_zone;

server {

location /status {

vhost_traffic_status_display;

vhost_traffic_status_display_format html;

}

}

检查config

/home/software/nginx/sbin/nginx -t

重启

/home/software/nginx/sbin/nginx -s reload

检查

curl localhost/status/format/prometheus

添加到 prometheus

• job_name: '47nginx'

  metrics_path: '/status/format/prometheus'

  static_configs:

• targets: ['172.16.10.4']

• targets: ['172.16.10.7']

18.1解压安装****nginx-vts-exporte****r(后来发现用不上)

tar -zxvf nginx-vts-exporter-0.10.3.linux-amd64.tar.gz

mv nginx-vts-exporter-0.10.3.linux-amd64 nginx-exporter

rm -rf nginx-vts-exporter-0.10.3.linux-amd64.tar.gz
