For details on valid combinations of data items and information about how data items are summarized, see Chapter 2, “Data Items and Statistical Types.”
You can think of a view as a table. The data items in a view are represented by the columns in that table. The number of rows returned for a particular view depends upon the particular data items in the view. For example, a view with server-wide data returns a single row, whereas a view with per-device data returns one row for each device.
For example:
A view consisting of two data items returns the rate of requested locks for each lock type during the sample interval:
SMC_NAME_LOCK_TYPE, SMC_STAT_VALUE_SAMPLE SMC_NAME_LOCK_COUNT, SMC_STAT_RATE_SAMPLE
A view consisting of one data item returns the rate of requested locks summarized for all lock types during the sample interval:
SMC_NAME_LOCK_COUNT, SMC_STAT_RATE_SAMPLE
