Problem:
Only DNS information is seen on the Home --> Clarity Live page.
Diagnostics:The issue will occur if either AMON_PASSIVE_AP_STATION_STATS_INFO_MESSAGE is not being received or not sent in appropriate format. To verify this, enable qlog for raw amon information being received:
qlog enable amon_dump_raw
Once the qlog has sufficient amount of data, we can decode the information using the following set of commands for the mentioned message type:
qlog_decoder --notail --nofollow -decoder papi --msg_type AMON_PASSIVE_AP_STATION_STATS_INFO path_to_the_qlog_dump file > path_to_decoded_file
The individual messages will look as follows:
172.30.120.69 --> This would be the source IP which would not necessarily be the configured LMS IP.

the LMS_IP parameter seen for this of utmost importance as it needs to be a PHYSICAL IP ADDRESS configured on the controller and not the Virtaul or VRRP IP.
SolutionIf AMON_PASSIVE_AP_STATION_STATS_INFO_MESSAGE is not seen on the Airwave dump file:
This issue might be seen if CpSec is enabled on the controller, if it is, then the AP related STAT messages would be sent over UDP port 8209, confirm if the port is open between the controller and the Airwave server.
If is seen with the incorrect / VRRP IP address:
The LMS_IP parameter is fetched from the LMS information either discovered by the AP using master discovery methods or could be configured from AP system profile under the Configuration --> Wireless --> AP Configuration --> Select AP Group --> AP --> AP system --> LMS Settings --> LMS IP. We can update this value to be the physical IP address of the controller to resolve the Clarity information not seen issue:
