Neighbours CDP/LLDP remote device alert

Is there an available alert for neighbours CDP/LLDP remote device? I’m looking for a method to detect up/down status for Cisco Accesss Points using the C9800-40 controller. I haven’t been able to define the correct and accurate alerting for up/down status regarding these model Cisco APs, in relation with the Cisco C9800-40 WLAN controller.

Cisco C9130AXI-B
AIR-AP3802I-B-K9
CW9166I-B

Thank you.
