System Overview

The CA IDMS Performance Monitor is a performance and tuning tool you can use to monitor hardware and software resource utilization in a DC/UCF system.

Components

Performance Monitor includes the following components:

Component	User	Statistics Collected
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

Windowing

All three Performance Monitor components are implemented through windowing. Windowing provides the following.

Comprehensive online help. You can request help at any time by using the HELP command. The position of the cursor at the time of the request indicates the required level of information. Online help explains the meaning of each Performance Monitor field.
The ability to control more data than can fit on the terminal screen. For example, you can scroll to the right to see additional columns of data.
Flexible screen displays. You can edit and sort screens to display data in a more meaningful format.
