在Windows上以编程方式获取每进程磁盘io统计信息？ [英] Programmatically getting per-process disk io statistics on Windows?

问题描述

我想显示一个进程列表（Windows，C ++），以及以KB /秒为单位从磁盘读取和写入的数量。

I would like to display a list of processes (Windows, C++) and how much they are reading and writing from the disk in KB/sec.

Windows 7的监视器有能力，所以我应该能够做同样的。

The Resource Monitor of Windows 7 has the ability so I should be able to do the same.

但是我无法找到相关的API调用或在perfmon计数器中找到任何东西。

However I have unable to find a relevant API-call or find anything in the perfmon counters. Could anyone point me in the direction?

推荐答案

您可以致电 GetProcessIoCounters 以获取每个进程的总磁盘I / O数据 - 您需要跟踪增量并转换为基于时间的速率

You can call GetProcessIoCounters to get overall disk I/O data per process - you'll need to keep track of deltas and converting to time-based rate yourself.

此API将告诉您I / O操作的总数以及总字节数。

This API will tell you total number of I/O operations as well as total bytes.
