Rows in the Databases tab are presented on two levels in a tree view:
Aggregate rowThe top level row is an aggregate row. This row shows consolidated information for a database across all of its partitions. It provides an overview of the current state of the entire database. If a column contains numeric values, the aggregate row shows the sum for all partitions. If a column contains values that cannot be aggregated or do not have meaning on an aggregate basis, the aggregate row is blank. —
Partition rowsâ€”Lower level rows show statistics for individual database partitions. For a multi-partition database, a list of partition rows descends from the aggregate row. For a single-partition database, only one row descends from the aggregate row.
Tip: Initially, aggregate rows are collapsed. Click the + button beside an aggregate row to expand its list of partition rows.
