Overview
Logs keep information records of selected events occurred in or detected by Kerio Control. Each log is displayed in a window in the Logs section. For this particular content, we will focus on warning logs in Kerio Control. The warning logs display warning messages about errors of little significance, e.g., error in communication of the server, web administration interface, etc.
Warning messages displayed in the log do not greatly affect Kerio Control's operation or functionality. Logs can, however, indicate certain (or possible) problems. The warning log can help if for example a user is complaining that certain services are not working.
