Added new log lines and more info to some existing log lines

I needed these logs in my debug sessions. I think this will help others too.

Hi @korayvt !
Thank you for your contribution!

Could you please extend your description with following information to make our job easier:

• How did you change logging?
• In what cases is it printed?
• Examples of before and after
• Is it an opt-in option? Is there any configuration?

Regarding last question - it is important we try to keep compatibility and at least try and document logging changes for version release

Thank you!
