UniFi AP connection quality (CCQ) graph

[aleferrari]

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?

===========================================

I attach a screenshot.

Not showing graph on port at librenms

Click one of the graphs, right click on the broken part and copy the image url, paste into a browser and add &debug=true to the end of it, it should produce some text which might tell you what’s going on. If not, click one of the images and click show rrd command and see what that says. If not, check your web server and librenms logs.

Try that

For now, what I got…

Debug:

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

The CCQ value is not sent by SNMP , 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.

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.

Hi,

Please let me some examples:

CCQ is supported
Ubiquiti UniFi 4.0.10.9653

CCQ is not supported
Ubiquiti UniFi 4.0.42.10433
Ubiquiti UniFi 4.3.28.11361
Ubiquiti UniFi 5.43.56.12784

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

Regards,
