The NHibernate Profiler allows a developer to analyze the behaviors between the domain and data layer more effectively. If you are using NHibernate I think this piece of software should be in your arsenal of tools. Oh, and for you Java folks it works against Hibernate.
Session Filtering
Before I start the analysis notice to the left we have an unfiltered view of our current sessions. If you look a bit closer, you’ll notice that the recent statements list contains some added noise. To remedy this we will apply a filter to all session statements containing a url path for image,css and JavaScript files.
Locate the Filter component, in the upper right window of NH Profiler. 
- Click on the filter icon and in the dropdown list of the Edit Filter window choose filtering for “Sessions by URL.
- Click the Add button.
- Choose the not containing operator.
- Enter the text for filtering. In my example I want to filter URL’s being sourced with the text '/Assets/’.
- Click apply.
And voila! we now have a more concise session list.
When the analysis is complex try to make it simpler with filters! In a future discussion we will look into how NH Prof can diff sessions and what insight we can gain from doing this.
