Tier interaction profiling provides additional information about the execution times in functions of multitiered applications that communicate with databases through ADO.NET. Data is collected only for synchronous function calls.
Requirements
- Visual Studio Enterprise
The Interactions View displays tier interaction data in two panes:
The master pane is a hierarchical tree. The top level row contains aggregated data for the database connections of an ASP.NET page or a process. Child nodes contain aggregated data for the database connections of the parent.
When you click a database call node in the master pane, data for the instance of the database call is displayed in the details pane.
Time is displayed as the number of milliseconds or the number of CPU clock ticks. To change the time unit displayed, click the Tools menu, click Options, and then choose one of the Show time values as options.
