Monitoring Directory Search Activity with PMOMON › The Purpose of PMOMON

The Purpose of PMOMON

CA PMO provides a monitor called PMOMON. PMOMON consists of a set of displays that are one or more screens in length. The displays contain statistics on various aspects of directory search activity on your system, including CA PMO participation in those searches and its performance and cost benefits. If you have more than one CPU, PMOMON shows statistics for the CPU on which it is running; it does not combine statistics across systems.

CA PMO collects the statistics for PMOMON from the time it becomes active on your system or from the time you issue the F PMO,RESET command. This command clears CA PMO statistics, but it does not clear the managed list or hash tables.

The remainder of this chapter explains how you:

• Invoke an interactive version of PMOMON under TSO or CA Roscoe
• Interpret the PMOMON displays
• Issue various PMOMON commands
• Use PMOMON as a batch job that produces hardcopy versions of the displays

Note: This chapter contains many references to CA PMO parameters. CA PMO parameters are a set of characteristics that control CA PMO behavior. For information on these parameters, see the chapter "Using Parameters."

• This chapter also refers to CA PMO commands. These are instructions that you may specify at the system console or as a batch job. For more information, see the chapter "Issuing Commands."
• References to the z/OS operating system throughout the CA PMO documentation pertain to the supported versions of z/OS and OS/390 operating systems.
