Per the instructions on this support page I tried to pull the logs
https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=556197187331574&parent=SrDetailText&sourceId=3-19484347901&id=1172435.1&_afrWindowMode=0&_adf.ctrl-state=5jvexs422_62
But on my iStream server, I am not able to find the logs on any of the 3 given paths, in fact any of these path does not exist :
C:\InSystems\IStream\Publisher-3.2\logs
C:\Whitehill\IStream\Publisher-4.X\logs
C:\Program Files\Oracle\IStream Publisher-4.3\logs
Below screenshot shows my production and their version

Thanks,
