Introduction MRTG (Multi Router Traffic Grapher, MRTG) is a tool software used to monitor network link traffic load. It obtains device traffic information through the SNMP protocol, in addition, the traffic load is displayed to the user in HTML document containing PNG format, and the traffic load is displayed in a very intuitive form (the output result example of MRTG can be obtained at the website http://www.stat.ee.ethz.ch/mrtg ).

General operating system performance mainly related to the main problems are: Processor usage, memory footprint, disk i/0 operations, and network traffic.To view Windows performance, in most cases through Windows Task Manager, you can eject task Manager by typing: taskmgr in the command line. Task Manager can view: CPU usage, memory usage, and network traffic.Using Windows Task Manager is intuitive and the UI works fine. However, there are some drawbacks, such as: The performance parameters can
