如何将Sentry与.NET 6.0 Worker Service集成？

我综合了Sentry与 .NET Core 6.0工人服务这边走：

NuGet: 哨兵3.17.1

// Program.cs:

using Sentry;

var sentryDsn = Environment.GetEnvironmentVariable("SENTRY_DSN");
using (SentrySdk.Init(o =>
{
    o.Dsn = sentryDsn;
    o.Debug = true;
    o.TracesSampleRate = 1.0;
}))
{
    IHost host = Host.CreateDefaultBuilder(args)
    .ConfigureServices(services =>
    {
        services.AddHostedService<Worker>();
    })
    .Build();

    await host.RunAsync();
}

// Worker.cs:

namespace demo_heroku_sentry_worker;
using Sentry;

public class Worker : BackgroundService
{
    private readonly ILogger<Worker> _logger;

    public Worker(ILogger<Worker> logger)
    {
        _logger = logger;
    }

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        while (!stoppingToken.IsCancellationRequested)
        {
            _logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);

            try
            {
                throw new ApplicationException("Exception inside of worker service");
            }
            catch (Exception e)
            {
                SentrySdk.CaptureException(e);
            }

            await Task.Delay(10000, stoppingToken);
        }
    }
}

这在某种程度上是有效的，因为我在我的 Sentry 仪表板上看到了手动捕获的错误。但是，我担心在应用程序输出上收到的这些警告消息：

      Worker running at: 05/11/2022 15:51:06 +02:00
  Debug: Failed to report an error on a session because there is none active.
   Info: Capturing event.
  Debug: Running processor on exception: Exception inside of worker service
  Debug: Creating SentryStackTrace. isCurrentStackTrace: False.
  Debug: Running main event processor on: Event abb5b3e2ee3a4dbd***********
   Info: Envelope queued up: 'abb5b3e2ee3a4dbda50ef***********'
  Debug: Envelope abb5b3e2ee3a4dbda50e*********** handed off to transport. #1 in queue.

我有什么遗漏的吗？

一些东西：

• 您最初实现它的方式没有任何问题。您显示的调试日志只是 Sentry 正在正常工作。如果您不想看到它们，请不要设置o.Debug = true;

• 您有手动读取的代码SENTRY_DSN环境变量并将其设置为o.Dsn在初始化期间。这是多余的，因为 SDK 会already如果您未在代码中传递 DSN，请查找该环境变量。执行其中之一，但不要同时执行两者。

• 如果您担心该消息"Failed to report an error on a session because there is none active."- 这只是说您还没有开始会话，所以 Sentry 的“释放生命值 https://docs.sentry.io/product/releases/health/" 功能将不起作用。您可以通过手动调用来启用它SentrySdk.StartSession(); and SentrySdk.EndSession();在应用程序中适当的位置，或者通过设置o.AutoSessionTracking = true;这更容易。后者将在 Sentry SDK 初始化时启动会话，并在释放时结束会话。

• 虽然您展示的方法没有任何问题，但您可以从中获得更好的功能日志集成 https://docs.sentry.io/platforms/dotnet/guides/extensions-logging/。示例代码here https://github.com/getsentry/sentry-dotnet/blob/9f7caf11366ef2d73346e7c176ff2478a6904455/samples/Sentry.Samples.GenericHost/Program.cs显示如何将其与通用主机一起使用。使用 nuget 包Sentry.Extensions.Logging https://www.nuget.org/packages/Sentry.Extensions.Logging.

把它们放在一起：

IHost host = Host.CreateDefaultBuilder(args)
    .ConfigureServices(services =>
    {
        services.AddHostedService<Worker>();
    })
    .ConfigureLogging(logging =>
    {
        logging.AddSentry(o =>
        {
            // o.Dsn = "(only if not using the env var)"; 
            o.TracesSampleRate = 1.0;
            o.AutoSessionTracking = true;
        });
    }
    .Build();

await host.RunAsync();
