System Use Reporting

System Use Reporting

The System Use Reports are a set of computer utilization time graphs and reports. They provide snapshots of system activity that can be augmented by User-Defined Reports. In general, these reports provide for the presentation of resource utilization information relative to dates and time and are laid out to aid the data processing manager in performing the following functions:

• identifying changing resource utilization trends early
• maintaining satisfactory customer service levels
• reducing resource contention through proper scheduling

The System Use Reports assist the data center manager in performing these and other functions. When used properly, these reports can be a powerful and efficient management tool.

This chapter contains an overview of System Use Report interpretation and then a detailed look at each of the categories of reports.

Note: The System Use Reports are based on combined SMF data. The EXTDATA System Use Reports, (SYSDAY1, SYSDAY2, SYSWEEK1, and TAPEMNT) use RMF records. Therefore, results cannot be compared. See the EXTDATA Reporting chapter in this guide for more information.
