![]() | 2 vibbow 187 天前 ![]() 这是 feature NOTE The Disk counter has been removed from the Performance tab in Windows Server 2012. This is because there is significant performance impact to collect Disk metrics on a Server due to the overhead Task Manager may cause in querying each Disk IO for each process/thread on individual disk. |
3 ar16 187 天前 @vibbow 感谢,顺藤摸瓜查到了怎么开启: prints: Both Logical and Physical Disk Performance counters on this system are automatically enabled on demand. For legacy applications using IOCTL_DISK_PERFORMANCE to retrieve raw counters, you can use -Y or -N to forcibly enable or disable. No restart is required. David Balaic CommentedFeb 1, 2023 at 9:56 |
