The xmperf program monitors statistics of the system. The xmperf program is not generally installed automatically with AIX. It is installable from the Performance Toolbox for AIX.

The xmperf program lets users set up data recording of numerous performance variables and then output the files to a spreadsheet format with time and date stamps. You can use the spread sheet for analysis.

The xmperf program is a GUI program, so you can monitor performance of the system without recording data. It offers all of the benefits of previously mentioned tools in one complete package.

Since xmperf is so large, it requires education to use it, and that education is beyond the scope of this book.
