A threshold is a boundary of acceptable or normal business transaction performance. Splunk AppDynamics provides default thresholds against which it compares the performance of every business transaction. Each transaction is classified into a user experience: normal, slow, very slow, stall, or error transaction.

The user experience reflects the performance of a transaction instance relative to the usual performance of the business transaction. This page provides information about refining the criteria by which the classification is applied, based on your requirements.
