How can I get Windows data like CPU usage, etc.?

问题:

How can I get Windows data like CPU usage, physical memory, and network utilization and bandwidth, similar to what I see in Task Manager? I'm using C++.

回答1:

You can get CPU usage using the performance data. If you want data for only one (or a few processes) it may be simpler to call GetProcessTimes every few seconds.

It's generally difficult to pin down exactly what physical memory usage even means. Until you do, trying to describe how to measure it is pretty pointless.

You can get some information about network utilization with GetIpStatistics.

You can get the rated bandwidths of the installed network adapters with GetIfTable.
