System Overview (PI)
- Organization of this page
Function
The System Overview (PI) record stores Performance data per unit time on the Windows performance objects listed below.
The System Overview (PI) record stores information for determining whether the system is being properly used. Each Windows performance objective is explained below.
-
Cache object
The Cache object monitors information on the file system cache, which is a physical memory area for managing data to achieve high-speed access to data without accessing a disk during the operation of the cache manager and the file system driver.
Because the cache is normally used by applications, it can also be used as an indicator for application I/O operations. If the memory size is small, the cache is also small, and thus effective operations cannot be expected.
-
Memory object
The Memory object manages physical and virtual memory operations.
The physical memory consists of RAM (random access memory) area while the virtual memory consists of areas inside both the physical memory and disks.
The virtual memory area is mapped onto the physical memory area, and pages that are not accessed for a certain amount of time are saved to the virtual memory to ensure effective use of the physical memory.
Paging is the transfer of codes and data between a disk and the physical memory based on page-in (loading of pages into the physical memory) and page-out (moving of pages to the virtual memory).
A page fault is an interrupt that occurs when an attempt is made to access a page that does not exist in the physical memory. Memory shortage caused by excessive paging can cause delays in system processing.
-
Objects object
The Objects object monitors the system's logical objects, such as processes, threads, mutex, and semaphore.
Each object needs memory for storing the basic information on itself. This information can be used to detect unnecessary resource consumption.
-
Processor object and Processor Information object
The Processor object and Processor Information object monitors the processor's processing state. A computer has multiple processors.
A processor is part of a computer that executes arithmetic operations and logical computation, initialization of peripheral device operations, and execution of process threads.
-
Redirector object
The Redirector object monitors the network connection initiated by a client computer.
-
Server object
The Server object monitors the server computer's communication between networks.
-
System object
The System object monitors various processing states of all processors within the entire system.

A value between 0 and 32,767 seconds can be specified (a value within the range specified for Collection Interval). Use this item to distribute the collection load, because executing data collection all at once results in concentration of the processing workload. Note that the data collection duration to be recorded is the same as the Collection Interval, regardless of the value specified for Collection Offset.
