Apparatus and computer program products are provided to monitor and report
performance data of a device such as a data storage drive. A plurality of
quantitative values are obtained from feedback and measurement mechanisms
in a data storage device of a first model during operation of the storage
device. The plurality of quantitative values are normalized. Then, one or
more qualitative values are generated from one or more normalized
quantitative values and evaluated against corresponding baseline
performance values established for the first model.
