you try to gather performance counter information for a 32-bit process on a
64-bit computer that is running Microsoft Windows Server 2003, some performance counter
objects are not available.Note
When you gather performance information for a 64-bit process in
this scenario, all the performance counter objects are available.
issue occurs because 32-bit versions of some performance counter objects are
not implemented in 64-bit versions of Windows Server 2003. In the 64-bit
versions of Windows, not all performance counters have 32-bit versions that are
designed to run on the Windows on Windows 64 (WOW64) 32-bit subsystem.
determine whether a 32-bit performance counter object is available on a
64-bit version of Windows Server 2003, follow these steps:
- Copy the Perfmon.msc file from the System32 folder to the
- Click Start, click Run,
type cmd, and then click OK.
- Change to the Syswow64 directory.
- Type the following command, and then press ENTER:
/32 perfmon.mscThis command runs System Monitor in 32-bit emulation mode.
- Use System Monitor to determine whether the performance counter object is
If the performance counter object does not appear when you run
System Monitor in 32-bit emulation mode but does appear when you run
System Monitor as you typically do, the 32-bit version of that performance counter
probably has not been implemented.
