Is Queries and Performance Monitoring supported on .NET Framework 4.7.2 and Entity Framework 6.4.0?

[edgariscoding]

I can't seem to get this to work, I thought it was automatically configured.

Using packages Sentry, Sentry.AspNet, Sentry.DiagnosticSource, and Sentry.EntityFramework v4.13.0

This is my Global.asax.cs file:

using System;
using System.Web.Http;

using Sentry;
using Sentry.AspNet;
using Sentry.Extensibility;

using Picsoft.Common;

namespace MyApp.API
{
    public class WebApiApplication : System.Web.HttpApplication
    {
        private IDisposable _sentry;

        protected void Application_Start()
        {
            // Initialize Sentry to capture AppDomain unhandled exceptions and more.
            _sentry = SentrySdk.Init(o =>
            {
                // DSN for CiraNet API Sentry project
                o.Dsn = ConfigurationHelper.SentryDsn;

                // Sets the release version in Sentry, for local developments this will default to 0.0.0.0
                o.Release = ConfigurationHelper.ReleaseVersion;

                // Sets the current environment in Sentry
                o.Environment = Platform.IsWebServer() ? ConfigurationHelper.Environment : "Local";

                // Automatically captures HTTP client errors, like bad response codes, as error events and reports them to Sentry
                o.CaptureFailedRequests = true;

                // Opt-in to send things like UserId and UserName if a user is logged-in
                o.SendDefaultPii = true;

                // Sample rate for your traced transactions: Captures 100% of transactions if not defined in appSettings
                o.TracesSampleRate = ConfigurationHelper.SentryTracesSampleRate;

                // If you also installed the Sentry.EntityFramework package
                o.AddEntityFramework();

                // RequestSize.Always sends the request body to Sentry
                o.AddAspNet(RequestSize.Always);
            });

            GlobalConfiguration.Configure(WebApiConfig.Register);
        }

        // Global error catcher
        protected void Application_Error()
        {
            Server.CaptureLastError();
        }

        protected void Application_BeginRequest()
        {
            Context.StartOrContinueTrace();
        }

        protected void Application_EndRequest()
        {
            Context.FinishSentryTransaction();
        }

        protected void Application_End()
        {
            // Flushes out events before shutting down.
            _sentry?.Dispose();
        }
    }
}

@edgariscoding what do you mean by "can't seem to get this to work"? What are you seeing vs what you're expecting to see?

I guess I was expecting certain tabs in the Sentry dashboard to be populated with database queries and such, as can be seen on this documentation.

This is all I see though:

Thanks @edgariscoding - Performance reporting is supported in .NET Framework - I don't think you'll get queries unless you get transactions so first step would be to work out why you're not seeing transactions come through in the performance dashboard.

It looks like you're calling StartOrContinueTrace:

        protected void Application_BeginRequest()
        {
            Context.StartOrContinueTrace();
        }

Can you try calling StartSentryTransaction there instead and see whether you start seeing transactions coming through to Sentry?

It looks to me like there might be an issue with the implementation of StartOrContinueTrace (this returns a transaction context but doesn't appear to use that context to start a new transaction)...
