ETW记忆 [英] ETW Memory

问题描述

大家好，

我创建了一个使用ETW跟踪事件的应用程序。但我观察到，当我在3.5上运行我的应用程序时，需要很高的内存。我正在使用"Microsoft.Diagnostics.Tracing.TraceEvent"带有版本"1.0.41"的nuget包。看起来像ETW这样的
正在将事件堆叠在"Microsoft.Diagnostics.Tracing.Utilities.HistoryDictionary + HistoryValue< Int32>"中。地图。但ETW从不清理地图，所以一旦事件发生，他们只是将它存储到这个地图，以便在下一个事件
带有相同参数时查找。任何人都可以帮助我如何在mu程序中清理这张地图，这样我就无法达到我的记忆限制。我在4.5框架上使用最新版本的DLL运行相同的应用程序，但这是唯一支持.NEt框架的版本
3.5。

I've made an application that uses ETW for tracing events. But I observed that when I'm running my application on 3.5 it takes high memory. I'm using "Microsoft.Diagnostics.Tracing.TraceEvent" nuget package with version "1.0.41". It seems like ETW is stacking up events in "Microsoft.Diagnostics.Tracing.Utilities.HistoryDictionary+HistoryValue<Int32>" map. But ETW never cleaning up the map so once events comes to them they just store it to this map for look up when next event comes with same parameters. Can anybody help me how can i clean up this map in mu program so that I won't reach my memory limits. I'm running same application on 4.5 framework with latest version of DLLs but this is the only version that supports .NEt framework 3.5.

谢谢

Hi Wenchung Shang，

Hi Wenchung Shang,

感谢您在此发帖。

对于您的问题，全局未启用ETW堆跟踪，因为它很昂贵。在一个进程的每个堆分配上记录一个调用堆栈可能是一个庞大的数据量。

For your question, ETW heap tracing is not enabled globally because it is expensive. Recording a call stack on every heap allocation for just one process can be a huge volume of data.

请通过指定要跟踪的进程的名称来使ETW堆跟踪工作，然后记录堆事件。

Please make ETW heap tracing work by specifying the name of the process to be traced, and then recording heap events.
