添加 Microsoft ApplicationInsights Telemetry 后出现 OutOfMemoryException

Question

我们最近在我们的网站上添加了遥测技术（我们一直是运行由 Microsoft Azure 门户自动添加的遥测技术），但现在我已经使用配置文件 nugets 实现了页面视图和整个机制等等。

然后在发布后，它运行持续了几天，然后在午夜左右爆炸，（我知道我应该点燃蜡烛并让一位俄罗斯教皇祝福服务器，因为邪恶势力显然已经参与其中）。

异常：

代码：

 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}");
        }
    }

有疑问的是：

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

上面的代码会导致内存泄漏还是更隐蔽的原因？

Answer 1

答案是也许。 TelemetryClient 不是 IDisposable 但 TelemetryConfiguration 是，所以：

替换后

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

和

    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);
    }

它再也没有回来
