Tblspace Metrics

These metrics take a tblspace name as the metric scope. A tblspace name is composed of the database name, a colon, and the table name (database:table). For fragmented tables, the tblspace represents the sum of all fragments in a table. To obtain measurements for an individual fragment in a fragmented table, use the Fragment Metric class.
