Continuous system-performance monitoring with the topas command

The topas command reports vital statistics about the activity on the local system, such as real memory size and the number of write system calls.

The topas command uses the curses library to display its output in a format suitable for viewing on an 80x25 character-based display or in a window of at least the same size on a graphical display. The topas command extracts and displays statistics from the system with a default interval of two seconds. The topas command offers the following alternate screens:

• Overall system statistics
• List of busiest processes
• WLM statistics
• List of hot physical disks
• Logical partition display
• Cross-Partition View

The bos.perf.tools fileset and the perfagent.tools fileset must be installed on the system to run the topas command.
