I'm trying to send metrics/traces from my ASP.NET Core 7 application to Grafana.

我正试图从我的ASP.NET Core 7应用程序向Grafana发送度量/跟踪。

Here's my Docker Compose file.

这是我的《码头工人》作文文件。

version: '3.4'

networks:
  my-network:
    name: my_network

services:
  sample.restaurant.server:
    image: ${DOCKER_REGISTRY-}samplerestaurantserver
    build:

      dockerfile: sample/Sample.Restaurant.Server/Dockerfile
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+:443;http://+:80
      - OTEL_EXPORTER_OTLP_ENDPOINT=grpc://otel-collector:4317
      - OTEL_METRICS_EXPORTER=otlp

    ports:

    volumes:

    depends_on:

    image: otel/opentelemetry-collector
    ports:
      - 4317:4317
    volumes:
      - ./collector-config.yml:/etc/otel-collector/collector-config.yml
    networks:

    depends_on:
      - otel-collector
    networks:
      - my-network

volumes:
  grafana_data: {}

And here's my collector config:

下面是我的收集器配置：

receivers:
  otlp:
    protocols:
      grpc:

exporters:
  otlp:
    endpoint: otel-collector:4317

service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: [otlp]
    metrics:
      receivers: [otlp]
      exporters: [otlp]

And here's my service collection extension method that configures OpenTelemetry.

下面是配置OpenTelemeter的服务集合扩展方法。

public static class TelemetryConfiguration
{
    public static IServiceCollection AddTelemetry(this IServiceCollection services,
        IWebHostEnvironment webHostEnvironment,
        string telemetryNamespace)
    {
        services.AddOpenTelemetry()
            .ConfigureResource(resource =>
            {
                resource
                    .AddService(
                        serviceName: webHostEnvironment.ApplicationName,
                        serviceNamespace: telemetryNamespace,
                        serviceVersion: Assembly.GetEntryAssembly()?.GetName().Version?.ToString() ?? "1.0.0",
                        serviceInstanceId: Environment.MachineName)
                    .AddAttributes(new Dictionary<string, object>
                    {
                        { "deployment.environment", webHostEnvironment.EnvironmentName }
                    });
            })
            .WithMetrics(metrics =>
            {
                metrics
                    .AddAspNetCoreInstrumentation()
                    .AddConsoleExporter((exporterOptions, metricReaderOptions) =>
                    {
                        metricReaderOptions.PeriodicExportingMetricReaderOptions.ExportIntervalMilliseconds = 1000;
                    })
                    .AddOtlpExporter(builder => builder.Endpoint = new Uri("http://localhost:4317"));
            })
            .WithTracing(tracing =>
            {
                tracing
                    .AddAspNetCoreInstrumentation()
                    .AddConsoleExporter()
                    .AddOtlpExporter(builder => builder.Endpoint = new Uri("http://localhost:4317"));
            });

        return services;
    }
}

Firstly, is this correctly configured?

首先，这是否配置正确？

Secondly, how do I setup the data source in Grafana to receive the data from my collector?

其次，如何在Grafana中设置数据源以从我的收集器接收数据？

The issue here is that you're attempting to use the OpenTelemetry collector as a Datastore. It collects, processes and forwards data to datastores, so in your example, you'll need to add a series of datastores for the various signals.

这里的问题是，您正在尝试将OpenTelemeter收集器用作数据存储。它收集、处理数据并将其转发到数据存储，因此在您的示例中，您需要为各种信号添加一系列数据存储。

My recommendation would be:

我的建议是：

• Traces - Jaeger


• Metrics - Prometheus


• Logs - OpenSearch

If you want to, you can then use the free local version of Grafana to visualise things like Metrics.

如果你愿意，你可以使用Grafana的免费本地版本来可视化像Metrics这样的东西。

For production, I'd highly recommend thinking about a SaaS solution as scaling of those can be hard if you're not used to running lots of containers and datastores. That said, all of those OSS/Free solutions can be hosted and scaled if you choose to.

对于生产，我强烈建议考虑SaaS解决方案，因为如果您不习惯运行大量容器和数据存储，扩展这些解决方案可能会很困难。也就是说，如果您选择的话，所有这些OSS/Free解决方案都可以托管和扩展。

If you're open to using Grafana Cloud for storing your data, it's quite simple to ingest OTLP. Here's the related documentation.

如果您愿意使用Grafana Cloud存储您的数据，那么使用OTLP非常简单。以下是相关文档。

You would need to sign up for Grafana Cloud (there's a free tier) and change your collector config according to the template below:

您需要注册Grafana Cloud(有一个免费级别)，并根据以下模板更改您的收集器配置：

extensions:
  basicauth/otlp:
    client_auth:
      username: <instanceID>
      password: <Cloud Access Policy token>

exporters:
  otlphttp:
    auth:
      authenticator: basicauth/otlp
    endpoint: https://otlp-gateway-<zone>.grafana.net/otlp

service:
  extensions: [basicauth/otlp]
  pipelines:
    metrics:
      receivers: [...]
      processors: [...]
      exporters: [..., otlphttp]
    traces:
      receivers: [...]
      processors: [...]
      exporters: [..., otlphttp]
    logs:
      receivers: [...]
