User documentation

To operate a network, it is important to get an overview about the currently raised alarms. The application offers basic fault management of devices supporting ONF-TR-532. The alarms are classified according to the severity level (warning, minor, major, critical).

Specification

“Fault” User Interface should be implemented to show the Alarm notifications of the devices.

Below are the UI elements to be implemented.

The graphical user interface is separated in three Expansion Panels.

  1. Current Alarm Notifications
  2. Alarm Notifications
  3. Alarm Log

The table view implements the common ux-framework-table supporting sorting, filtering and pagination on the server.

The following panels shows the tables with its respective data.

1)     Current Alarm Notifications

It lists all current active faults in the network. In addition, it also lists alarms sent by the SDN controller itself, which detects connections losses to the NetConf server (connectionLossOAM) or which detects connection loss to a devices via a mediator to a device (connectionLossNeOAM).

The Current Alarm Notification panel shows the table with the below columns.
