我们如何在C＃中获取磁盘性能信息

Question

I want to get the following information about the disk performance.

I used MSStorageDriver_FailurePredictThresholds , MSStorageDriver_ATAPISmartData , MSStorageDriver_FailurePredictStatus class to get relative information but not getting the right result.

Answer 1

This isn't everything you wanted, but the Win32_PerfFormattedData_PerfDisk_PhysicalDisk WMI class gives you current read / write / transfer rate and activity time. It also gives some averages but I'm not sure how they are calculated (it seems odd that AvgDiskBytesPerWrite is 0)

// NOTE: Use ManagementObjectSearcher to find the path your interested in
var path = "Win32_PerfFormattedData_PerfDisk_PhysicalDisk.Name='0 C:'";
var wmiObj = new ManagementObject(path);
wmiObj.Properties.Cast<PropertyData>().ToDictionary(p => p.Name, p => p.Value).Dump();

/* OUTPUT */
