Introduction › System Use Reports

System Use Reports

System Use Reports present an overall picture of activity within the operating system. SMF records carry the operating system related data, so they are the only meaningful input to the System Use Reports.

There are two types of System Use Reports:

• Overall System Utilization
• Detail Job or Program Activity Analysis

There are five overall System Utilization Reports:

• CPU Activity Graphs
• Multiprogramming Activity Report
• Computer Utilization Summary
• Resource Utilization Graphs
• Disk and Tape Activity Graphs

The detail Job or Program Activity Analysis Reports highlight specific resource utilization statistics by job or program. Each report is ordered by one of the following resources:

• Number of times used
• CPU time
• EXCPs
• Service rate
• Paging
• I/O index
• CPU page rate

You can produce one or all of these System Use Reports in a single run of CA JARS.
