CLR Profiler – Object Aging report for an Asp.Net Web Application

The CLR Profiler provides various types of reports which help in determining the performance of the application and tuning it. The “Histogram by Age” report shows the object allocating aging report which shows the object allocation across time intervals.

To view the “Histogram by Age” report, use the following steps.

     Start CLR Profiler.

Make sure that the following check boxes are selected:

Profiling active

Allocations

Calls

On the File menu, click Profile ASP.NET.

CLR Profiler shuts down Internet Information Services (IIS), adds environment variables that are needed for profiling, and restarts IIS. CLR Profiler then prompts you to load the ASP.NET application and waits for the ASP.NET worker process to start.

Use Microsoft Internet Explorer to browse to the ASP.NET application you want to profile.

You can also run your Web application by using a client tool such as Microsoft Application Center Test (ACT.)

When you have finished running the application, click Kill ASP.NET in the CLR Profiler main window.

CLR Profiler shuts down IIS, removes the environment variables, and restarts IIS.

Once the profiler is stopped, it will automatically display the Summary Report.
     Close the   Summary report

Click on View -> Histogram by Age option to open the Report

The following screen shows on how the “Histogram by Age” report details will be displayed for a simple Web Application.
