Monitoring memory usage is a critical task for maintaining the health and performance of any system. In the AIX operating system, there are several commands and tools that can be used to check memory usage.
One of the most commonly used commands is the “vmstat” command. Vmstat provides a real-time view of memory usage, as well as other system statistics. The “p” option of vmstat provides a detailed breakdown of memory usage, including the amount of memory that is being used by the operating system, by applications, and by the file system cache.
