Physical Disks

• Volume—Name of the physical drive for which statistical information is gathered.

• Queue Length—Average number of both read and write requests that were queued for the

selected disk during the sample interval.

• Disk Busy Time %—Percentage of elapsed time that the selected disk-drive is servicing read

or writes requests.

Processes

• Process—Name of the task for which statistical information is gathered.

• Threads—Number of threads currently active in this process. An instruction is the basic unit

of execution in a processor, and a thread is the object that executes instructions. Every running

process has at least one thread.

• Private Bytes—Current number of bytes this process has allocated that cannot be shared with

other processes.

• PageFile Bytes—Current number of bytes this process has used in the paging files. Paging

files are used to store pages of memory used by the process that are not contained in other

files. All processes share paging files and a lack of space in paging files can prevent other

processes from allocating memory.

• Working Set—Current number of bytes in the working set of this process. The working set is

the set of memory pages touched recently by the threads in the process. If free memory in the

computer is above a threshold, pages are left in the working set of a process even if they are

not in use. When free memory falls below the threshold, pages are trimmed from working

sets. If they are needed, they are soft-faulted back into the working set before they leave main

memory.

• Page Faults/sec—Rate at which the page faults occur in the executing threads within 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 does not cause the page to be fetched from disk if it is on

the standby list and already in main memory, or if it is in use by another process with whom

the page is shared.

• % CPU Time—Percentage of elapsed time that all 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. On multi-processor machines, the maximum value of the counter is 100 % times

the number of processors.

• % Privileged CPU Time—Percentage of elapsed time that the threads of the process have spent

executing code in privileged mode. When a Windows NT 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. Unlike some early operating systems, Windows NT 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 Windows NT on behalf of your application might be displayed in other

subsystem processes in addition to the privileged time in your process.
