These are the Profilers added so you can check the Trace -> UnrealInsights after you started a trace

And when clicking in the Insights timeline you can search for profilers. It would look something like this when you search for Reactional.Category.Name.

In the future add these to docs:

DECLARE_CYCLE_STAT(TEXT("Reactional.Engine.Update"), STAT_ReactionalEngineUpdate, STATGROUP_Reactional); DECLARE_CYCLE_STAT(TEXT("Reactional.Audio.FilterRead"), STAT_ReactionalAudioFilterRead, STATGROUP_Reactional); DECLARE_CYCLE_STAT(TEXT("Reactional.Memory.Management"), STAT_ReactionalMemoryManagement, STATGROUP_Reactional); DECLARE_CYCLE_STAT(TEXT("Reactional.Resource.Cleanup"), STAT_ReactionalResourceCleanup, STATGROUP_Reactional); DECLARE_CYCLE_STAT(TEXT("Reactional.Events.Processing"), STAT_ReactionalEventProcessing, STATGROUP_Reactional);
