To generate an input file, compile a single file with UnrealBuildTool and redirect the output to a text file:
UnrealBuildTool.exe UE4Editor Win64 Development -SingleFile="E:\P4\Engine\Source\Runtime\Core\Private\Misc\CoreGlobals.cpp" -Timing > E:\Output.txt
To convert into a trace readable by chrome:
AutomationTool.exe ParseMsvcTimingInfo -File=E:\Output.txt
Output file will be written to the same directory as the input file, but with a json extension.
