A UI component which show the current alarms events of devices/PNFs supporting ONF-TR-532.
Fault
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).
Views
The graphical user interface is separated in three views.
Current Alarms
It lists all current active faults in the network. In addition is also list alarms send by the SDN controller itself, which detects connections losses to the NetConf server (connectionLossOAM) or which detects connection loss to a device via a mediator to a device (connectionLossNeOAM).
Alarm Notifications
As long as the view is open, it lists all alarm notification reached by the SDN Controller. Please note that refreshing the view will start the collection again. Previous alarm notification can be viewed in the alarm log.
Alarm Log
Next to the current active alarms an alarm log list all alarm notifications of the past.
Implementation
The application has two parts. While the server is listening for NetConf notifications to store them in the data base the client retrieves the information from the data base and displays them in a grid view.
The server synchronizes with the current alarm lists of the devices and calculates based on raise and clear notifications the current alarm status of the network. The current alarms are stored in a data base. In addition, all Problem Notifications received by the SDN controller are stored. There is no logic implemented on the client.
An alarm status bar on top of each graphical user interface informs the operator about the health status of the network.
