prometheus grafana的安装使用：https://nanxiang.blog.csdn.net/article/details/135384541

本文说下监控nginx，prometheus grafana nginx 安装配置和使用

Docker 镜像下载地址： https://hub.docker.com
比较好的hub.docker.com///-- https://hub.docker.com/u/bitnami
grafana监控面板：https://grafana.com/grafana/dashboards

prometheus_exporter_10">prometheus exporter容器

在docker中下载nginx/nginx-prometheus-exporter镜像，并使用该镜像去运行容器

docker pull nginx/nginx-prometheus-exporter

docker run -itd -p 9113:9113 --name nginx-exporter  --restart=always -v /etc/localtime:/etc/localtime  nginx/nginx-prometheus-exporter -nginx.scrape-uri http://192.168.1.230/stub_status

192.168.1.230 被监控的nginx服务器的地址

nginx_19">监控nginx

nginxstub_status_20">nginx需要加载stub_status监控

[root@test230 ~]# nginx -V

nginx_29">查看有没有，如果有，去配置下nginx

   location /stub_status {
                stub_status on;
                access_log off;
                #allow 127.0.0.1; # 允许本地访问
                #deny all; # 禁止其他IP访问
        }

nginx_40">重要，需要重启nginx

[root@test230 ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@test230 ~]# nginx -s stop
[root@test230 ~]# systemctl start nginx

只是nginx -s reload是不生效的，一定要重启

测试监控是否成功

查看nginx是否已经开启监控stub

    [root@test230 opt]# curl http://127.0.0.1/stub_status
    Active connections: 6 
    server accepts handled requests
     9702 9702 165810 
    Reading: 0 Writing: 1 Waiting: 5 

在浏览器中输入http://192.168.1.230:9113，如果显示出测量数据就表示成功.
需要注意的是输入的IP地址为nginx/nginx-prometheus-exporter容器所配置的IP地址。

prometheusnginxexporter_68">prometheus中添加nginx-exporter

• job_name: nginx
  static_configs:
• targets: [‘1192.168.1.230:9113’]
  #192.168.1.230:9113与第三步测试的地址一至

配置 grafana

需要对应应的nginx/nginx-prometheus-exporter支持的仪表盘(dasdbord)
在grafana仪表盘中导入11280模块
或者自行去找合适的监控dasdbord

这个只是简单的监控，具体负责请自行分析吧。。
