A system and method for summarizing changes between a first set of metrics and a second set of metrics are disclosed. An example method includes obtaining and categorizing a first set of metrics for an application. A second set of metrics for the application may be obtained and categorized. A statistical process may be used to determine metrics that should be displayed. Metrics may be organized into a metric tree data structure that is hierarchical including parent metrics and child submetrics. Metrics that have been determined to be displayed may be displayed in the tree data structure so that the metrics are selectable with a single user input. In response to receiving a selection of a metric via the single user input, traffic categories and submetrics may be displayed that are children of the metric within the tree data structure may be displayed.
