Win32_PerfFormattedData_TermService_TerminalServicesSession: Total number of handles currently opened by this process. This number is the sum of the handles currently opened by each thread in this process.

Win32_PerfFormattedData_TermService_TerminalServicesSession: Number of input async framing errors. These can be caused by a noisy transmission line. Using a smaller packet size may help in some cases.

Win32_PerfFormattedData_TermService_TerminalServicesSession: Number of input async overflow errors. These can be caused by a lack of buffer space available on the host.

Win32_PerfFormattedData_TermService_TerminalServicesSession: Number of input async overrun errors. These can be caused by the baud rate being faster than the computer can handle, or by a non-16550 serial line being used. Overruns can also occur if too many high speed serial lines are active at one time for the processor's power.

Win32_PerfFormattedData_TermService_TerminalServicesSession: Rate at which page faults occur in the threads executing in this process. A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This can cause the page not to be fetched from disk if it is on the standby list and hence already in main memory, or if it is in use by another process with which the page is shared.

Win32_PerfFormattedData_TermService_TerminalServicesSession: Current number of bytes this process has used in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files.

Win32_PerfFormattedData_TermService_TerminalServicesSession: Percentage of elapsed time that the threads of the process have spent executing code in privileged mode. When an- operating system service is called, the service often runs in privileged mode to gain access to system-private data. Such data is protected from access by threads executing in user mode. Calls to the system can be explicit or implicit, such as page faults or interrupts. The operating system uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. These subsystem processes provide additional protection. Therefore, some work done by the operating system on behalf of your application might appear in other subsystem processes in addition to the privileged time in your process.

Win32_PerfFormattedData_TermService_TerminalServicesSession: Percentage of elapsed time that all of the threads of this process used the processor to execute instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.

Win32_PerfFormattedData_TermService_TerminalServicesSession: Percentage of elapsed time that this process's threads have spent executing code in user mode. Applications, environment subsystems and integral subsystems execute in user mode. Code executing in user mode cannot damage the integrity of the operating system executive, kernel, and device drivers. The operating system uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. These subsystem processes provide additional protection. Therefore, some work done by the operating system on behalf of your application might appear in other subsystem processes in addition to the privileged time in your process.
