Audit Logs

Log files listed under the audit folder contain the log files stored in the controller's audit folder.

These files record KAS runtime activities and organize events by functional area, making it easier to locate and analyze specific system actions.

Use audit logs to review and investigate activities such as:

  • Backup and restore actions
  • Configuration and parameter changes
  • Controller application events
  • Firmware update operations
  • Project downloads and application activity
  • User authentication attempts
