Logging interaction with external IDP

Hi all,
we are installign keycloak server on premise on customer datacenter.
We are using keycloak to broker their IDP provider (forgerock) is it possible.
As for now we need to log all the interaction from our keycloak to their forge rock.
Does anybody know how to configure logging to achieve suche result?
Or Is there any document where such configuration is explained?
thanks all
