Исключение OutOfMemoryException после добавления телеметрии Microsoft ApplicationInsights

#asp.net-mvc #memory-leaks #out-of-memory #azure-application-insights #telemetry

Вопрос:

Недавно мы добавили телеметрию на наш веб-сайт (мы запускали тот, который автоматически добавляется порталом Microsoft Azure), но теперь я реализовал просмотры страниц и весь механизм с помощью nugets файлов конфигурации и тому подобного.

Затем, после релиза, он работал пару дней, а затем взорвался около полуночи (я знаю, что должен был зажечь свечу и попросить русского папу благословить серверы, так как в этом явно были замешаны злые силы).

Исключение:

Код:

  public class BaseController : Controller, IyyyController
 {
    private TelemetryClient telemetry = new TelemetryClient(new Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration(ConfigurationManager.AppSettings["ApplicationInsightKey"]));

 ...

 protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        base.OnActionExecuting(filterContext);
        var user = ViewBag.CurrentUser = db.GetCurrentUser();
        SendApplicationInsightsTelemetry(filterContext, user);
    }

 private void SendApplicationInsightsTelemetry(ActionExecutingContext filterContext, User user)
    {
        try
        {
            PageViewTelemetry telemetrypageView = new PageViewTelemetry()
            {
                Name = filterContext?.HttpContext?.Request?.RawUrl,
                Url = filterContext?.HttpContext?.Request?.Url
            };

            if (filterContext.HttpContext.Session["Id"] == null)
                filterContext.HttpContext.Session["Id"] = Guid.NewGuid().ToString();

            telemetrypageView.Context.Session.Id = filterContext.HttpContext.Session["Id"].ToString();

            if (user != null)
            {
                telemetrypageView.Context.User.Id = user.zzz.ToString();
                telemetrypageView.Context.User.AccountId = user.ooo;
            }

            telemetry.TrackPageView(telemetrypageView);
        }
        catch (Exception e)
        {
            Trace.TraceError($"{nameof(SendApplicationInsightsTelemetry)}, {e.Message}");
        }
    }

Сомнительный момент заключается в том, что:

private TelemetryClient telemetry = new TelemetryClient(new Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration(ConfigurationManager.AppSettings["ApplicationInsightKey"]));

Мог ли приведенный выше фрагмент кода вызвать утечку памяти или это что-то более коварное?

Ответ №1:

Ответ может быть. TelemetryClient нет IDisposable TelemetryConfiguration , но есть, так что:

После замены

 private TelemetryClient telemetry = new TelemetryClient(new Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration(ConfigurationManager.AppSettings["ApplicationInsightKey"]));

с

     private readonly TelemetryClient telemetry;
    private readonly Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration telemetryConfiguration;

    protected BaseController(ProjectPlanContext dbContext)
    {
        telemetryConfiguration = new Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration(ConfigurationManager.AppSettings["ApplicationInsightKey"]);
        telemetry = new TelemetryClient(telemetryConfiguration);
    }

    protected override void Dispose(bool disposing)
    {
        telemetryConfiguration.Dispose();
        base.Dispose(disposing);
    }

это никогда не возвращалось
