使用PerformanceCounters定位特定的驱动器 [英] Using PerformanceCounters to target specific drives

问题描述

伙计们，我有以下代码:

Guys, I have the following code:

using System.Diagnostics;

private PerformanceCounter diskRead = new PerformanceCounter();
private PerformanceCounter diskWrite = new PerformanceCounter();

diskRead.CategoryName = "PhysicalDisk";
diskRead.CounterName = "Disk Reads/sec";
diskRead.InstanceName = "_Total";

diskWrite.CategoryName = "PhysicalDisk";
diskWrite.CounterName = "Disk Writes/sec";
diskWrite.InstanceName = "_Total";

此代码跟踪每秒的磁盘读取数和每秒的磁盘写入数，并且工作正常.我的问题是，如何跟踪一个特定驱动器的读写?我的计算机中有3个硬盘驱动器，现在它总共返回了所有3个驱动器的总和.如何特别选择要监视的驱动器?

This code keeps track of Disk Reads per second and Disk Writes per second and it works fine. My question is, how do I keep track of reads and writes of one specific drive? I have 3 hard drives in my computer and right now its returning a total of all 3 drives combined. How can I specifically chose which drive I want to monitor?

推荐答案

您应将"_Total"替换为适当的驱动器号:

You should replace "_Total" with the appropriate drive number:

  diskRead.InstanceName = "0";

应该检查一下.您需要指定名称，例如"0 C: D:". kes.

Should've checked that. You need to specify the name like "0 C: D:". Yikes.

您可以使用

    var cat = new System.Diagnostics.PerformanceCounterCategory("PhysicalDisk");
    var instNames = cat.GetInstanceNames();

过滤掉以数字开头的名称是绝对安全的. (_Total也在列表中.)

And it is probaly safe to filter out the names that start with a number. (_Total is also in the list).
