    Using Loupe with ASP.NET - Page Hit Metric
    In This Topic

    Each time a request is processed by the ASP.NET processing engine a metric is recorded with the total time for the request and the time for each stage of the ASP.NET pipeline.

    What Data is Captured by the Page Hit Metric

    The Page Hit metric captures several values for every request to the ASP.NET engine. 

    Caption Type Description Summary Function
    Page String The page name without path Count
    Absolute Path String The full path from the root of the web site to the page that was requested including the page Count
    Query String String The query string used for the request Count
    Total Request Duration Double The entire time it took for the request to be satisfied Average
    Authenticate Request Duration Double The time it took for the request to be authenticated Average
    Authorize Request Duration Double The time it took for the request to be authorized Average
    Resolve Request Cache Duration Double The time it took for the request to be looked up in cache Average
    Acquire Request State Duration Double The time it took for the request state to be acquired Average
    Request Handler Execute Duration Double The time it took for the request handler to execute. This includes the time for most ASP.NET page code. Average
    Release Request State Duration Double The time it took for the request state to be released Average
    Update Request Cache Duration Double The time it took for the request cache to be updated Average
    Log Request Duration Double The time it took for the request to be logged Average
    Cached Response Boolean Indicates if the response was served from the output cache instead of being generated. Average

    The captions align with the ASP.NET documentation for the various phases of processing a request and are listed in order above.  Most code written for ASP.NET is executed in the Request Handler phase and counted as the Request Handler Execute Duration.  If a response is returned from the ASP.NET output cache then the request handler is never executed and the Cached response value is true.

    Charting and Graphing the Page Hit Metric

    First, locate the Page Hit Metric in the session you're interested in:

    Selecting the Page Hit Metric

    Selecting the Page Hit Metric

    You can then drag the metric onto a new graph or chart to analyze different information.  For example, if you chart the Average Total Request Duration by Absolute Path with a secondary plot of the number of hits you get the following chart:
