dotMemory 2020.3 Help

Profile .NET Core Application

To profile a .NET Core application

  1. Run dotMemory as a standalone application. The dotMemory window will open.

  2. In the left panel, select Local.

  3. In the middle panel in Profile Application, select .NET Core Application.

  4. In the right panel, in .NET Core Application:

    • In Application, specify the path to the application executable (if it's a self-contained deployment) or to a library file (if it's a framework-dependent deployment).

    • Optionally, if your application requires command-line arguments, select Advanced and specify Arguments.

    • Optionally, if your application creates a number of processes and you want to profile a specific one, select Advanced and Profile child processes. If required, add a process filter as described in the Filtering Child Processes section.

  5. If you want dotMemory to start collecting the stack trace allocation data* right after the profiling session starts, select the Collect memory allocation and traffic data from start option in the right panel.
    For more details on profiler options, refer to the Profiler Options section.
  6. Optionally, if you are going to control profiling session (take snapshots, end session, and so on) using the API (rather than the Controller window), select Control profiling via API. For more details on how to control profiling using the API, refer to the Control Profiling Session with API chapter.

  7. Click Run.

  8. Take snapshots. For more details on how to control profiling session, refer to Control Profiling Session (if you control the session manually) or to Control Profiling Session with API (if you control profiling using the API).

  9. After you collect the data, either close the profiled application or detach the profiler using the Detach button of the Controller window. If you use the API to control profiling, detaching must be executed by your code.

  10. Analyze the collected snapshots.
