DEV390 - Intellitrace®, What Is It and How Can I Use It To My Benefits?Marcel de VriesTechnology Manager Microsoft Application DevelopmentInfo Support

Intellitrace®, what is it?

Analogy with aviation industryHow do you reproduce a airplane crash?

This is a difficult problem to solve and they found a solutionBlack box

All relevant voice information from cockpitAll relevant telemetry

Intellitrace® is kind of similar for your Managed programs

Works for .NET 2.0 and up

Intellitrace®

Intellitrace® provides a debug logfile that you can use to debug your program at a different moment in timeLogfile contains Events

Debug eventsExeption events.NET framework events

Can be configured what is relevant for your application

Configuration

Log can also contain call informationIntellitrace® collects a record of each call entry and exit. On entry, Intellitrace® collects name and value information for each parameter. For arrays, only the first 256 objects are recorded. For objects, only the top level of the structure is recorded. On exit, Intellitrace® collects the return value of the method.

Has more impact on application performance!

Configure Intellitrace® in Visual Studio 2010

Tools -> Options -> Intellitrace -> Intellitrace events

So what is captured when all turned on?

private void btnCalcTip_Click(object sender, RoutedEventArgs e){

string country = cmbCountries.SelectedItem.ToString();double billAmount = Double.Parse(txtBillAmount.Text, CultureInfo.CurrentCulture); string qualityOfService = GetQualityOfServiceString();

int numCourses = GetNumberOfCourses();int numberOfFlies = 0;

numberOfFlies = GetNumberOfFlies(); // calculate tipdouble tip = tipCalcBl.CalculateTip(country, billAmount, qualityOfService, numCourses, numberOfFlies);

}

Return value of method

Return value of method + value of all argument

Local assignement of primitive not captured

What about objects that are passed between methods?

Only primitives within the object are capturedPointers to other objects

Only capture if there was a pointer or nullShows as “unavailable” in locals windows

Address

string Streetstring Citystring Statestring Zip

IEnumerable<Phone>

IEnumerator <T>

Employee

int IDstring FirstNamestring LastNamestring Identitystring ServiceAreas

Data that is collected

So we know there was an Address, but not it’s contained values

There was no phone (null)

Using Intellitrace® in Visual studio and in your builds

Team build and Symbols

Symbols are extremely important when you use Intellitrace® from other environments

Log collected on test or production machineDebugging with logfile on your VS machine

Needs to find the sources that are used for that particular build

Symbols contain information what code file is the source of a binary

Better known as PDB filesAlways compile your products with symbols

Does not incur performance penalties!

Symbols and Team BuildTeam Foundation Server build provides the option to save the symbols to a symbol server

Indexes all sources so they can be found based on your binarySymbol server setup is nothing more then providing a share

Symbols and visual Studio

Set visual studio to enable symbol server supportTools -> Options ->Debugging -> General

Symbols and visual Studio

Set Visual Studio to include your symbol serverTools -> Options ->Debugging -> Symbols

Intellitrace® in production scenario’s

It is possible to ad your own events

Tunes Intellitrace® to your specific needsSpeeds startup timeReduces runtime overhead, since you can collect only from your own module

Announced feature at TechEd North AmericaMenu option to add a custom Intellitrace® event just by right click in your source code in VS2012 Post RTM

Also possible in 2010Edit the DefaultCollectionPlan.xml in VS directory
