Core Logs are being written to C:\Program Files\UNIFY Solutions\Identity Broker\Services\Logs There doesn't seem to be a place to do this in the UI.
This location currently can't be changed. If you need to log to a different directory, you can create another CSV log writer configured to log to the desired directory. Alternatively, you could try replacing the C:\Program Files\UNIFY Solutions\Identity Broker\Services\Logs directory with a symbolic link to the desired directory.
The log location is configurable in v5.3
