Windows 10新默认浏览器– Microsoft Edge中的开发人员工具配备了必要的工具，可帮助 Web 开发人员在^{(Developer Tools)}Microsoft Edge中测试他们的网站。但是，可能会发生故障。因此，为了防止此类偶然故障并确保所有事情都按预期工作，Edge在其解决方案旁边有一个专门的错误消息部分。例如，当您在DevTools内存面板中看到错误消息“^{(Memory Panel)}启动分析会话时发生错误^{(An error occurred while starting the profiling session)}”时，您可以执行以下操作来快速修复它。

在Edge DevTools^{(Edge DevTools)}中启动分析会话时出错

要修复与Edge (Chromium) DevTools的内存面板^{(Memory Panel)}相关的此错误，我们需要采取两个步骤：

1. 访问 Microsoft^{(Access Microsoft)} (R)诊断^{(Diagnostics)} 中心标准收集器服务^{(Hub Standard Collector Service)}。
2. 重新启动Microsoft (R)诊断^{(Diagnostics)} 中心标准收集器服务^{(Hub Standard Collector Service)}。

内存^(Memory)面板主要衡量您对内存资源的使用情况，并比较不同代码执行状态下的堆快照。内存^(Memory)面板提供三种不同类型的分析：

内存^(Memory)面板提供三种不同类型的分析：

• 堆快照
• 记录分配时间表
• 记录分配配置文件

使用此面板，我们可以发现在大多数常见情况下影响页面性能的问题，包括内存泄漏和膨胀。

1] 访问 Microsoft (R) 诊断中心标准收集器服务^{(1] Access Microsoft (R) Diagnostics Hub Standard Collector Service)}

要访问Microsoft (R)诊断^{(Diagnostics)} 中心标准收集器服务^{(Hub Standard Collector Service)}，请打开“运行”对话框，在其中键入“services.msc”并按Enter。

然后，从右侧打开的服务（本地）面板中，找到^(Services)Microsoft (R) 诊断中心标准收集器服务^{(Microsoft (R) Diagnostics Hub Standard Collector Service)}。

2]重新启动Microsoft（R）诊断中心标准收集器服务^{(2] Restart the Microsoft (R) Diagnostics Hub Standard Collector Service)}

现在，在访问Microsoft (R) Diagnostics Hub Standard Collector Service后，右键单击它并选择“重新启动^(Restart)”选项。

完成后，关闭Microsoft Edge 开发人员工具^{(Microsoft Edge Developer Tools)}和选项卡。打开一个新选项卡，导航到您的页面，然后按F12。

您现在应该能够开始分析，如上面的屏幕截图所示。

就是这样！

An error occurred while starting the profiling session in Edge DevTools

The Devеloper Tools in the new default browser of Windows 10 – Microѕoft Edge have been еquіpped with necessarу tools to help web developers test their web sites in Microsoft Edge. Howevеr, failures can occur. So, to prevеnt ѕuch occasional fаilures and ensure all things work as expected, Edge has a dedicated section for error messages alongside their solutions. For instance, when you see an error mеssage ‘An error occurred while starting the profiling session’ in the DevTools Memory Panel, here’s what you can do to fix it quickly.

An error occurred while starting the profiling session in Edge DevTools

To fix this error associated with the Memory Panel of Edge (Chromium) DevTools, we’ll need to take two steps:

1. Access Microsoft (R) Diagnostics Hub Standard Collector Service.
2. Restart the Microsoft (R) Diagnostics Hub Standard Collector Service.

A Memory panel primarily measures your use of memory resources and compare heap snapshots at different states of code execution. The Memory panel provides profiling of three different types:

The Memory panel provides profiling of three different types:

• Heap Snapshot
• Record Allocation Timeline
• Record Allocation Profiles

Using this panel, we can find issues that affect the page performance in most common scenarios, including memory leaks and bloats.

1] Access Microsoft (R) Diagnostics Hub Standard Collector Service

To access Microsoft (R) Diagnostics Hub Standard Collector Service, open the ‘Run’ dialog box, type ‘services.msc’ in it and press Enter.

Then, from the Services (local) panel that opens on the right-hand side, locate Microsoft (R) Diagnostics Hub Standard Collector Service.

2] Restart the Microsoft (R) Diagnostics Hub Standard Collector Service

Now, after getting at Microsoft (R) Diagnostics Hub Standard Collector Service, right-click it and choose ‘Restart’ option.

When done, close the Microsoft Edge Developer Tools and the tab. Open a new tab, navigate to your page, and press F12.

You should now be able to begin profiling as seen in the screenshot above.

That’s it!
