When logging information about a node it would be very helpful if the information uniquely identified the node. With Magnolia 4.5.19 I see the following in the logs when activating two nodes:

INFO   info.magnolia.module.exchangesimple.BaseSyndicatorImpl 26.05.2014 17:23:51 -- Exchange: activation succeeded [/npodoc]
INFO   info.magnolia.module.exchangesimple.BaseSyndicatorImpl 26.05.2014 17:23:51 -- Exchange: activation succeeded [/npodoc/2013/maart/rijksmuseum]

I know that the first activation was a web page and the second was an image, but from the logs it is not obvious that the nodes with these paths are not in the same workspace.

I would argue that whenever a string representation of a node is used, just a path is not enough. Prefixing the path with the workspace would help.

It could look like this:

INFO   info.magnolia.module.exchangesimple.BaseSyndicatorImpl 26.05.2014 17:23:51 -- Exchange: activation succeeded [website:/npodoc]
INFO   info.magnolia.module.exchangesimple.BaseSyndicatorImpl 26.05.2014 17:23:51 -- Exchange: activation succeeded [media:/npodoc/2013/maart/rijksmuseum]

This could even be in the toString() method of Node implementations?
