System and logs

The following resources and requests expose the rc_visard’s system-level API. They enable

  • access to log files (system-wide or component-specific)
  • access to information about the device and run-time statistics such as date, MAC address, clock-time synchronization status, and available resources;
  • management of installed software licenses; and
  • the rc_visard to be updated with a new firmware image.
