Two or more interrelated hierarchies within a set of performance data may be integrated into a single hierarchy. The single hierarchy may be provided in a single user interface to allow a user to navigate the single hierarchy. By navigating through the single hierarchy, a user may view relationships between application elements, cumulative performance data for categories and elements, and other information. A single integrated hierarchy includes a sequence of node types. The node types for an integrated hierarchy may include categories, relationships and elements. The node types may repeat as a sequence within the hierarchy, and more than one node type may be combined into a single level of the hierarchy. Aggregated metrics such as response time may be displayed with the integrated hierarchy.
