Collecting Thread and Process Concurrency Data

  • Article

Note

Thread execution and visualization data cannot be collected or analyzed for Web sites. Resource contention data can be collected.

The Visual Studio Profiling Tools concurrency profiling method enables you to collect two types of concurrency data:

  • Resource contention data includes information about every synchronization event that causes a function in the profiled application to wait for access to a resource.

  • Thread execution data includes information about processor utilization, thread contention, thread migration, synchronization delays, areas of overlapped I/O, and other system events.

You can specify the concurrency profiling method by using one of the following procedures:

  • On the first page of the Profiling Wizard, click Concurrency, and then select or clear the Collect resource contention data and Collect thread execution data check boxes.

  • On the General page of the properties dialog box for the performance session, click Concurrency, and then select or clear the Collect resource contention data and Collect thread execution data check boxes.

  • On the Performance Explorer toolbar, in the Method list, click Concurrency.

Common Tasks

You can specify additional options in the Performance Session Property Pages dialog box of the performance session. To open this dialog box:

  • In Performance Explorer, right-click the performance session name, and then click Properties.

The tasks in the following table describe options that you can specify in the Performance Session Property Pages dialog box when you profile by using the concurrency method.
