UniFi AP connection quality (CCQ) graph

Hello community. I have a problem, which, although not critical, deprives me of accessing useful information.

I have linked my UniFi controller with which I manage my Ubiquiti access points, via SNMP, with my LibreNMS.
In this way, from LibreNMS I carry out the entire NMS task, leaving the controller for the IPAM and DCIM tasks.

Until then, everything is fine. I see all the information without problems, except for the connection quality graph in the upper right part of each AP’s file.
What do you think? Could it be that I am not receiving the CCQ values? Will the OID need to be modified?


Component Version
LibreNMS 23.11.0-29-g624eb5aa0 (2023-12-13T19:29:53-03:00)
DB Schema 2023_11_21_172239_increase_vminfo.vmwvmguestos_column_length (274)

Python 3.10.12
Database MariaDB 10.6.12-MariaDB-0ubuntu0.22.04.1
RRDTool 1.7.2
SNMP 5.9.1

I attach a screenshot.

Run that rrd command on your LibreNMS server and see what the output is.

The CCQ value is not sent by SNMP :roll_eyes:, but is calculated at source to be displayed in a proprietary web interface.

Maybe there is the problem with the graphics.

I will try to do reverse engineering to obtain it, and perhaps through extended SNMP, generate an OID that will send it to LibreNMS. :grimacing:

From there, I’ll load it as a custom OID, for sure.

Thank you so much.


Hi !

Unfortunately some newer unifi software does not support this OID.

The older versions is working well but the newer is not.

Please let me some examples:

CCQ is supported
Ubiquiti UniFi

CCQ is not supported
Ubiquiti UniFi
Ubiquiti UniFi
Ubiquiti UniFi

If you have valid support you should open a ticket at Ubiquiti.
