参考之前的文章->安装prometheus和Grafana教程

源代码

dotnet源代码

新建.net core7 web项目

修改Program.cs

using Prometheus;

namespace PrometheusStu01;

public class Program
{
    public static void Main(string[] args)
    {
        var builder = WebApplication.CreateBuilder(args);
        builder.Services.AddControllers();
        
        var app = builder.Build();
        
        app.UseRouting();
        //http请求的中间件,收集http请求信息的
        app.UseHttpMetrics();
        //映射监控地址为  /metrics
        app.MapMetrics();
        app.MapControllers();
        app.Run();
    }
}

安装prometheus-net.AspNetCore 8.2.1
访问http://localhost:5122/metrics

修改prometheus.yml

scrape_configs:
  # 省略其他配置
  - job_name: "asp.net core web"
    static_configs:
      - targets: ["127.0.0.1:5122"]

重启

修改Program.cs

using Prometheus;

namespace PrometheusStu01;

public class Program
{
    public static void Main(string[] args)
    {
        var builder = WebApplication.CreateBuilder(args);
        builder.Services.AddControllers();
        
        var app = builder.Build();
        
        app.UseRouting();
        //http请求的中间件,收集http请求信息的
        app.UseMetricServer();
        //看这里>^.^<
        app.UseMetricServer();
        //映射监控地址为  /metrics
        app.MapMetrics();
        app.MapControllers();
        app.Run();
    }
