aix performance monitoring commands

Linux There are many excellent tools to help us analyze the server performance indicators and assist in the development of debugging work. The following is only a list of commands that are relatively basic and are generally integrated in a Linux environment without having to be installed again. For more detailed commands, refer to Https://github.com/brendangregg/
