UX Maintenance

User documentation

The 'Maintenance' application provides the information of the Network Elements which are set for Maintenance, currently or in the future. User can manage devices to set the maintenance mode so that no unnecessary alarms are created. When the device is in Maintenance alarms are not forwarded to DCAE and when the device maintenance is turned off the alarms will start flowing again.

Users should have access to disable the Maintenance mode or change the maintenance start and end dates at any point of time by using the available options in actions column.
