App.Metrics not reporting to InfluxDB/Graphite locally (docker-compose/grafana/dotnet 6) about appmetrics

[gabriellima09]

Solved by using the following configs:

Program.cs

using App.Metrics;
using App.Metrics.AspNetCore;
using Microsoft.AspNetCore.Mvc;

var builder = WebApplication.CreateBuilder(args);

builder.WebHost.UseKestrel(options => 
{
   options.AllowSynchronousIO = true;
});

builder.Services
    .AddControllers()
    .AddMetrics();

// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
    
builder.Services.AddAppMetricsHealthPublishing();
builder.Services.AddAppMetricsSystemMetricsCollector();

builder.Host
        .ConfigureMetricsWithDefaults(builder =>
                {
                    builder.Report.ToInfluxDb(options =>
                    {
                        options.InfluxDb.Database = "demo";
                        options.InfluxDb.BaseUri = new Uri("http://127.0.0.1:8086");
                        options.InfluxDb.UserName = "user";
                        options.InfluxDb.Password = "123";
                        options.InfluxDb.CreateDataBaseIfNotExists = true;
                        options.FlushInterval = TimeSpan.FromSeconds(5);
                    });
                })
            .UseMetrics();

var app = builder.Build();

if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.MapControllers();

app.UseMetricsAllEndpoints();
app.UseMetricsAllMiddleware();

app.Run();

OBS: On Grafana datasource config you use the container_name to set it up and on dotnet app use the localhost IP 127.0.0.1
