Network monitoring is the most complex in all Linux subsystems, with too many factors, such as latency, blocking, conflict, and packet loss, even worse, the routers, switches, and wireless signals connected to Linux hosts all affect the overall network and it is difficult to judge whether the problem is caused by the Linux network subsystem or other devices, monitoring and network judgment are the most comp

KDESystemGuard (KSysguard) is a KDE tool for task management and performance monitoring. It adopts the client/server architecture and can monitor the local host or remote host. The following is the usage method: Default KDE System Guard window The front-end graphic interface uses sensors to obtain the information to be displayed. The sensor returns a simple value or more complex information, such as a table

Many domestic reference books confuse these two concepts, swapping is also translated as swap. in the operating system, a program is fully switched to the hard disk to free up memory for use by new programs, and only partial pages of the program are exchanged with paging) is two different concepts. Pure swapping is hard to see in modern operating systems, because it is time-consuming, laborious, and unnecessary to switch the entire program to the hard disk, modern
