This topic describes how to enable and configure file-based log rotation for audit logs and login history logs on the EX appliance. You can rotate these log files at a specified period of time, when they reach a specified file size, or when they take up a specified percentage of disk space. Configuring the criteria for individual file types overwrites the global configuration. For a full list of logging commands and their usage and parameters, see the CLI Command Reference.
