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
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
[root@test230 ~]# nginx -V

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
}
[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
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。
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。。
