Hello @Karol Trzcinski 
You can find some information about the Extractor under Services on the server where you installed it. You can also view the Extractor logs on the server.
Is that what you are looking for? Unfortunately, you don't see any detailed information in Celonis itself.
Best Regards
Jonas
                
     
                                    
            Hi @Karol Trzcinski,
 
In your data pool, go to the data connection that you would like to investigate. Press on the options button on the right hand side to see the overview of your example (see screenshot below).
 
Best regards,
