Tivoli® Decision Support for z/OS

Tivoli® Decision Support for z/OS is an IBM® product that collects and analyzes data from IBM® Z Workload Scheduler and other IBM® systems and products. You can build reports that help you with:
  • System overviews
  • Service levels
  • Availability
  • Performance and tuning
  • Capacity planning
  • Change and problem management
  • Accounting.

Many predefined reports are available. You can also generate your own reports to meet specific needs.

The reports use data from the IBM® Z Workload Scheduler job-tracking files. Tivoli® Decision Support for z/OS also collects data from the z/OS system and from products such as RMF™, TSO, IMS™ and NetView®. This means that data from IBM® Z Workload Scheduler and other systems can be shown together, or can be presented in separate reports.

Reports can be presented as plots, bar charts, pie charts, tower charts, histograms, surface charts, and other graphic formats. Tivoli® Decision Support for z/OS simply passes the data and formatting details to Graphic Data Display Manager (GDDM®), which does the rest. Tivoli® Decision Support for z/OS can also produce line graphs and histograms using character graphics, where GDDM®, is not available or the output device does not support graphics. For some reports, where you need the exact figures, numeric reports such as tables and matrices are more suitable.
