System monitor

from Wikipedia, the free encyclopedia

A system monitor is a local computer program for viewing and recording system resources (such as available memory , processor utilization , network activity). Most system monitors can display the system resources as curves with a time sequence in real time and record them if necessary. This enables you to monitor the computer more closely.

The system resources of servers and their computer networks are monitored by a service monitor.

Examples

Microsoft Windows

A program called "System Monitor" is part of Windows installations (Windows 9.x sysmon.exe ; Windows NT perfmon.exe ), but the program is not displayed in the Windows NT Start menu. The values ​​that you want to view can also come from another Windows PC via the network. This means that the system monitor can also be used for remote maintenance . In Windows XP this program is called "Performance" , in Windows Vista "Reliability and Performance Monitoring" , in Windows 7 and 8 the system monitor has been renamed "Performance Monitoring" .
