Description

Several fixes required

• Don't log entire tokens, just the identifier should be enough
• DAG ID (or unique number needs to be used). Otherwise we get only one file per session
• This should not go into the local-directory - since that isn't accessible. Instead the log directory would be a better place.

Marking as critical for 0.5.1 since this is very useful for debugging.
