Step 3: create a view

Views are defined groups of data items. The data items specified determine how the data is summarized. Since you can specify multiple views, the application has full flexibility in the gathering of data. For example, a view consisting of two data items (device name, value for sample and device I/O, rate for sample) returns the device I/O rate for each database device.

For details on valid combinations of data items and information about how data items are summarized, see Chapter 2, “Data Items and Statistical Types”

For examples of views, see Appendix A, “Examples of Views”.
