Hey swapnil.zambare,
Can you private message me the customer and inventory names for the instance in question? Also, please provide the IP addresses/hostnames of the WLCs you are not seeing hostnames for as well as missing APs.
Also, please include any IPs and device types for devices that are missing in the product alert report that you are expecting to see.
You can private message me by hovering over my username and selecting send message.
Thanks,
Justin
