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).
Overview Fault management:
“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 into three tabs:
The table view implements the common ux-framework-table supporting sorting, filtering and pagination on the server.
The following tabs should show a table with its respective data.
It lists all current active faults in the network. In addition, it also lists alarms sent by the SDN controller itself, which detects connection losses to the NetConf server (connectionLossOAM) or which detects connection loss to a device via a mediator to a device (connectionLossNeOAM).
Reload Button: Reloads/Refresh the Current Problems List
Sync button : Clears stuck alarms
The Current Alarm Notification panel shows the table with the below columns.
The sync button allows refreshing the current alarms for the visual NEs.
If the alarms are not indicated as active anymore, they will be removed from the list.
Clear stuck Alarm icon will only be available when there are Faults available else it wont be visible.
The "export to CSV" button will export the presented current problem list to a CSV File.
As long as the page is not fully refreshed (the browser reloaded), it lists all alarm notifications reached by the SDN Controller. Previous alarm notification can be viewed in the alarm log.
Alarm Notifications should be collected in real-time via websockets.
The Alarm Notification panel shows the table with the below columns.
Next to the currently active alarms, an alarm log lists all alarm notifications of the past.
The Alarm Log panel shows the table with the below columns.

The data is stored in an ElasticSearch database. The Data-Provider provides a REST-API to read the data.
Note: The alarm notifications are only updated via websockets. No REST-API is provided.
