In fact, for the same reason, the corresponding disk and network columns have also been disabled from the Processes tab of the Task Manager. An easy way to check Disk metrics is to use Resource Monitor. Disk metrics are very useful while troubleshooting performance issues on the server. This is because there is a 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/disk.

On the Task Manager Performance tab we can see real-time server performance, namely processor, memory, and network performance.
