Task Manager difference between Windows 8 and Windows Server 2012 RRS feed

  • Question

  • Today I found a strange difference between the Task Manager in Windows Server 2012 and Windows 8. In Windows Server 2012 you only see the tabs CPU and Memory by default. Why is this, and how can this be changed, because disk and network are grayed out in Windows Server 2012. Both versions are the RTM.

    WS2012
    In Windows 8 we see CPU, Memory, Disk and Network

    W8

  • Hi,

    Disk metrics are disabled by default on Windows Server 2012 because of significant performance impact, however, it is enabled in Windows 8.

    Use Resource Monitor to gauge Disk and Network IO usage.

  • Hi,

    Why not open resource monitor to search for more details about those information. This should be by design, as I can see network and disk are not used commonly as CPU and memory.

  • Yes, that's an option, but I use the Task Manager more when troubleshooting performance issues, so that's would be easier to have the overview right there. And Windows 8 has it implemented, why can't it implemented on Windows Server 2012 then?

    Is that in a virtual machine or a physical install of Server 2012?

  • Is there a registry setting we can turn it on in server 2012 with?  perfmon is a hog and I like the simplicity and look of the revamped task manager... Is there a registry key to modify or anything?

  • Open a command prompt and type

    diskperf -y

    this enables the disks to show in task manager


    but unfortunately, not the columns..... I haven't found an answer to that yet

    "Significant performance impact"? Could you elaborate? Why is it OK in Windows 8 but not Windows Server?

  • This is the explanation from the Windows Server Performance team:

    "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.  Disk metrics are very useful while troubleshooting performance related issues on the server."

    You can enable the disk IO by running:

    diskperf -y

    Note: this will only show up on the Performance tab (not the default Processes tab):

  • "significant performance impact" are the exact words used by Microsoft Official site but here "Syed Yusuf" who works at MSFT India R&D ¿?¿? attributes them to himself... mmmm... 

    You can't imagine how many people is scammed thru calls from "Microsoft Technicians" who validate their claims using posts at public forums.

    Even linkedIn fake Accounts.
