Please can you elaborate? I am assuming a typo and you mean changelogs, but I still don't understand the question. Do you mean the Samba Audit log? If so go to Webconfig > Server > Windows Networking > Windows File Share > Edit and enable the Audit logging. From memory this has a performance hit either on speed or log size, but I can't remember which. I have a feeling it is the logs which can get very large.
