How to activate/configure portal component logs in WAS 6.40?

Hi,

I am having some troubles finding a method to activate/configure the portal component logs on WAS 6.40.

I am talking about logs that were generated through the

com.sapportals.portal.prt.logger.ILogger interface.

On 6.20, the portal had some extra functionality under System administration->monitoring, but this has now been removed ( moved to visual admin?).

Anyone?

Regards

Dagfinn
