# ASE log messages

The following tables list the critical log messages from `controller.log` and `balancer.log` files. Note that the `balancer.log` file is not rotated while the `controller.log` file is rotated every 24 hours. For more information on API Security Enforcer (ASE) logs, see [ASE access, management, and audit logs](pingintelligence_ase_acess_management_audit_logs.html).

**controller.log messages:**
