This Document
This document is a CAE specification. It defines a performance data pool for the analysis and management of computer systems, and an organisation to facilitate the collection and use of such data. This set of performance metrics may be accessed by the two UMA interfaces:

The UMA Guide (see Part 1 of this specification). reviews the issues surrounding performance measurement in Open Systems, describes the general UMA architecture, and discusses user considerations in adopting the UMA.

The audience for the metrics defined in this document ranges from the end-user to the system developer. End-users (customers) will find them useful in measuring productivity. Performance analysts/engineers can use them for modelling, tuning and measuring/predicting capacity in systems/applications. Data centres and MIS organisations can use them to assess the quantity and quality of the computing services provided under Service Level Agreements with their customers. Hardware and software vendors can use them to assure the performance of their products during development and after release. Performance management application vendors can use them as standard metrics with the open application interface UMA provides, to develop their products.
