Abstract:

Particular embodiments generally relate to displaying database time using a treemap. A set of database time values is determined for a set of dimensions. The database time values measure performance of one or more databases by the time the database takes to respond to a request. The set of database time values is correlated to a set of cells in the treemap. A size of the cell is determined based on the database time value associated with it. For example, the database time value is correlated to an area of the cell. A layout of the set of cells is determined and the treemap is displayed using the layout. For example, the largest values of database time may be shown with the largest sized cells. This makes it easier for an administrator to review and analyze the database performance across multiple dimensions and determine problem areas affecting the performance of the one or more databases.
