The following two ETW session types are used to simplify the names of session and profile objects:
InSequentialFile sessions: These sessions are saved into a file sequentially, extending it until a preset maximum file size is reached. This behavior maps to the ETW sequential mode.
InBuffer sessions: These sessions save data in memory, overwriting the oldest data with the most recent data continually. They must be saved to a snapshot file for analysis. This behavior maps to the ETW buffering mode.
