I need help on displaying Laser Rx Power. Is there any guidance for me to enable it on Librenms?
I enabled it from devices to be viewed via snmp but nothing show up on Librenms.

My device: Generic Device

I use Cisco IOS Software to test now also does not show Optical Rx Power.
Any guidance please

Hi,

Take a look here: https://docs.librenms.org/Developing/Support-New-OS/

Thanks, I have read it and make Rx Power display however it can not get Rx Power data.

Hi @Jerry_Dao
If your device is not yet supported by LibreNMS, then you have to follow the link provided by TheGreatDoc.
If your device is already supported by LibreNMS (like a Cisco device) then Laser RX/TX dbm values are already polled, if available. Some devices are not provided those values over SNMP so that is normal they don’t show. For instance, Cisco 897 laser measurements are not available over SNMP, you need to ask Cisco to add it :smiley:
If you still have issues, then you’ll need to provide more details :

  • ./discovery.php -h -m sensors -v
  • ./poller.php -h -m sensors -v

Bye

Here are info for Cisco device:

Thanks in advanced.

Most of the devices in my company wont show Laser RX/TX dbm via SNMP,
I have one open source system (self made) to monitor Rx/Tx power by getting info from SSH connection.
Is there anyway to do the same with Librenms?
