windows - 在 Windows 上以编程方式读取程序的页面错误计数

Question

我希望我的 Windows C++ 程序能够读取它所导致的硬页面错误的数量。该程序未以管理员身份运行。 编辑添加:明确地说，我对整个系统的页面错误总数不感兴趣。

看起来 ETW 可能会为此导出计数器，但我在弄清楚 API 时遇到了很多困难，而且与管理员相比，普通用户可以访问哪些内容尚不清楚。

有没有人有这个功能的例子？还是在 Windows 上根本不可能？

(OT，但是这在 *nix 上容易得多吗？gerusage()，你就完成了。)

afai 可以说唯一的方法是使用 ETW(Windows 事件跟踪)来监视内核硬页面错误。事件负载有一个线程 ID，您可以将其与现有进程相关联(顺便说一句，这将是非常重要的)以生成每个进程的运行计数。我看不到任何方法可以获取每个进程的历史信息。

我可以向你保证这是一个难题，因为 Process Explorer在其每个进程显示中仅支持页面错误(软或硬)。

A page fault occurs when a sought-out page table entry is invalid. If the requested page needs to be brought in from disk, it is called a hard page fault (a very expensive operation), and all other types are considered soft page faults (a less expensive operation). A Page Fault event payload contains the virtual memory address for which a page fault happened and the instruction pointer that caused it. A hard page fault requires disk access to occur, which could be the first access to contents in a file or accesses to memory blocks that were paged out. Enabling Page Fault events causes a hard page fault to be logged as a page fault with a type Hard Page Fault. However, a hard fault typically has a considerably larger impact on performance, so a separate event is available just for a hard fault that can be enabled independently. A Hard Fault event payload has more data, such as file key, offset and thread ID, compared with a Page Fault event.
