Description
- in case of failures an O1 device sends a VES event of domain 'fault' to the VES Collector on SMO
- The VES collector forwards the fault content to the Message Bus (DMaaP)
- The DeviceManager component on O1-Controller polls for fault events on DMaaP and ...
- ... receives its content
- The DeviceManager within the O1-Controller processes the fault event and ...
- ... updates the alarm log.
Verification Command
The following command should display the content within the O1-Controller Alarm Log:
