The Multiprocessor page in the CPUs drilldown displays in separate charts the total processor utilization for all CPUs on the Windows system.

Spotlight is a powerful diagnostic and problem-resolution tool for Windows operating systems. Its unique user interface provides you with an intuitive, visual representation of the activity on the host machine.
For information on Spotlight on Windows, see these sections
Introductory material to Spotlight on Windows.
|Connect to a Windows System
|Create / Modify / Delete connections to Windows systems.
|The Spotlight home page shows the flow of information and commands between various sub-components and the size and status of internal resources such as processes, disk files and memory structures.
Spotlight alerts you to problems with your system by issuing an alarm. You can configure Spotlight in the level of severity that constitutes an alarm, to disable an alarm, and the actions Spotlight takes on raising the alarm.
|When you have isolated a problem, you can display a drilldown page, whose charts and tables provide a detailed breakdown of the underlying statistics.

The Memory | Summary page summarizes recent memory usage.

Charts on the Summary page
The Physical Memory chart shows how much physical memory (RAM) Windows is using.
Physical memory usage will normally remain close to the total amount of physical memory installed on the system unless the amount of physical memory you have exceeds the amount of virtual memory that Windows is using. Windows normally keeps some physical memory available (free) for immediate reuse.
|The total amount of memory in use by the program. This includes Physical Memory and space in the paging file. A steady increase in virtual memory usage can indicate that a process on the system has a memory leak.
Shows the rate at which pages are being swapped in and out of memory. The chart displays two data series:
A sustained high rate of paging can cause problems with overall system degradation due to disk thrashing and CPU load.
|Physical Memory Usage
The Physical Memory Usage chart shows how Windows is using physical memory.
It displays the following data series:
The Memory | Paging Activity page shows details of Windows paging activity and page files.

Charts and Grid on the Paging Activity page
|Charts and Grid
|Page File Transfers Chart
The Page File Transfers chart shows recent Windows paging activity. It shows the number of pages read (in) and written (out) per second to and from the Page Files.
Paging occurs when the Windows Virtual Memory Manager moves data or code between physical memory and disk. Sustained high paging rates can degrade system performance significantly.
|Page Faults Chart
The Page Faults chart shows the rate at which Windows is processing page faults. It compares the two types of page fault (soft and hard) and makes it easy to see the ratio between them.
A page fault occurs when a process references a page that is not in that processes working set (the set of pages visible to that process in physical memory). When this happens, the process has to wait while the Windows Virtual Memory Manager retrieves the page from virtual memory.
|Page Files Grid
The Page Files grid shows the page files in use by Windows.
Page files are disk files that the Windows Virtual Memory Manager uses to back physical memory. Code and data is moved between physical memory and the page files as required, giving processes on the system the illusion that there is much more physical memory available than there really is. The process of moving data and code between memory and disk is called paging.
The Page Files grid shows the following:
