Prometheus+Grafana可视化监控【Nginx状态】

Prometheus+Grafana部署请参考上篇文章: Prometheus+Grafana部署:

一、Prometheus监控NGINX

1、配置with-http_stub_status_module模块
查看当前NGINX是否支持with-http_stub_status_module 模块

# 如果没有输出则不支持,需要编译进行添加with-http_stub_status_module模块
./nginx -V 2>&1 | grep -o with-http_stub_status_module

2、添加status页面的

    server {
        listen   80;  
        location /nginx_status {
            stub_status on;
            access_log off;
            allow 127.0.0.1;
            deny all;
        }
}

重启NGINX

nginx -t
nginx -s reload

3、验证status页面是否可以访问

curl http://127.0.0.1/nginx_status

Active connections: 5 
server accepts handled requests
 5 5 7 
Reading: 0 Writing: 2 Waiting: 3 

4、安装nginx-prometheus-exporter
下载地址：https://github.com/nginxinc/nginx-prometheus-exporter/releases

wget https://github.com/nginxinc/nginx-prometheus-exporter/releases/download/v0.11.0/nginx-prometheus-exporter_0.11.0_linux_amd64.tar.gz
mkdir /usr/local/src/nginx-exporter
tar zxf nginx-prometheus-exporter_0.11.0_linux_amd64.tar.gz -C /usr/local/src/nginx-exporter

5、启动nginx-prometheus-exporter模块

cd /usr/local/src/nginx-exporter
nohup ./nginx-prometheus-exporter -nginx.scrape-uri http://127.0.0.1:80/nginx_status &

6、默认监听9113端口，防火墙中放开

firewall-cmd --add-port=9113/tcp --permanent 
firewall-cmd --reload 

7、prometheus.yml添加Job配置

  - job_name: 'nginx_7'
    metrics_path: '/metrics'
    scrape_interval: 10s
    static_configs:
      - targets: ['10.9.11.7:9113']

systemctl restart prometheus

8、验证
prometheus页面验证

二、Grafana添加NGINX监控模板

我这里内网环境，使用JSON格式进行导入

最终效果图如下：
