Sometimes, a trap comes in from a managed device that results in a message starting with;
"Unknown alert from device...."
The reason for this is that the Trap OIDs are not certified in Spectrum and require a customized mapping to be done for Spectrum to understand them.
Consequently, no alarm is generated and the trap simply remains as an event. To fix this situation, what you can do is create a customized event, which raises an alarm for these traps.
While Spectrum has many thousands of devices and their associated traps certified, the multitude of vendors and devices means that there will always be either new or less popular ones that are uncertified. In order to be able to understand the traps and events raised by these devices when they're discovered, Spectrum needs to have customisation implemented whereby the traps are mapped to events and attributes of the discovered yet uncertified models receiving them.
