Hello Emilio,

Thank you for contacting us,

The log files should all be there in that folder that you mentioned. If you can only see the logs from 5 days ago you can check your Historic Data Purging settings, there you can set the amount of days that will be logged. You can go to Setup > System Administration > Core & Probes, scroll to the bottom and there you can see the values. The default for the web server log is 30 days. Maybe yours is set to 5. For more information regarding the data purging configuration you can see this Link
