The CA IDMS Performance Monitor is a performance and tuning tool. The topics in this section describe the following information:
You can use Performance Monitor to monitor hardware and software resource utilization in a DC/UCF system.
Performance Monitor includes the following components:
|Realtime Monitor||DCAs, DBAs, operators, system programmers||Specific system-resource statistics at the time of the request|
|Interval Monitor||DCAs, DBAs||System-wide, wait-time statistics for a unit of time (for example, five minutes), which are necessary to track bottlenecks in resource utilization|
|Application Monitor||Application programmers, DCAs, DBAs||Statistics about resource usage by individual programs and chargeback/billing information by group code|
All three Performance Monitor components are implemented through windowing. Windowing provides the following.
For more information about windowing, see Windowing.
To begin a Performance Monitor session, enter the task code for the monitor you want to use:
|Billing component of the Application Monitor||pmbill|
When you enter a task code, the menu for the appropriate monitor is displayed. Each option on the menu represents a specific monitor screen.

Information on the Screen
The first three lines on your terminal screen define the product, release, date, time of day, window number for the current window (see Windowing) and refresh interval (if installed with the refresh option). This area also provides a field for entering commands and a message area.
The rest of the terminal screen contains one or more windows. Each window displays a monitor screen. The default window is the window that is displayed in the upper-left corner of the terminal screen. Performance Monitor displays as many windows at a time as possible. Use the windowing facility to manipulate the window displays, as described under Windowing.
Note: If secured external monitoring is enabled, only authorized users/groups are allowed to monitor security external systems selected by the Active System Summary function (PF19).
