Linux performance testing and monitoring sar commands Sar (System Activity Reporter System Activity Report) is one of the most comprehensive System performance analysis tools on Linux. It can report System activities from multiple parties, including: file read/write, system call usage, disk I/O, CPU efficiency, memory usage, process activity, and IPC-related activity. This document describes the sar

the most useful programs in my Linux System Management Toolkit.PmapThe PMAP command is used to report the amount of memory used by the server's process. You can use this tool to determine which processes on the server are allocated memory, and who is using memory in a large number of these processes.PS and PstreeThe two commands for PS and Pstree are the two right-hand assistants for Linux system administrators. They all display all currently running

server starts. If you don't want to wait until the server restarts, you can execute the init 3 command. Once your server is running in console mode, you can start with what we're going to do next. Iostat The Iostat command is used to display detailed information about the storage subsystem, which is typically used to monitor disk I/O. Pay special attention to the%iowait value in the iostat statistic, too large to indicate that your system storage subsystem is performing poorly. Meminfo and
