linux performance monitoring commands

Some Linux distributions provide GUI programs for system monitoring, such as SUSE Linux has a great and professional tool yast,kde the KDE System Guard is also excellent. Of course, to use these tools, you have to operate in front of the server, and these GUI programs take up a lot of system resources, so although the GUI is good for basic server health
