Nexus 5548 Transceiver Thresholds Wrong

Where does LibreNMS grab the thresholds for the transceivers.
For our Nexus 5548

I have some single mode transceivers showing as red.

This is what show interface transceiver details


If they are not fetched properly from the device then librenms does some auto threshold tuning. You can however set the thresholds manually in the health page of the device.

How can I get it to fetch properly from the device? I tired to rediscover the device. We have a lot of Cisco Nexus 5548 and would be a pain to manually do everyone.

Basically, you have to check if the device provides this information via SNMP. If yes, then you can add it in the YAML file that does the polling. We can help you.
