pfSense temperature graph

Hi all, I am having some issues with temperature graphs on pfSense hosts. All of them are showing error drawing graph. All other graphs on these hosts are working fine. So can anyone tell me are temperature graphs even supported for pfSense and if they are what can I do to make them work?

Pastebin the output of ./poller.php -h HOSTNAME -d -m sensors

Hi, thanks for replying
here is output of ./poller.php -h HOSTNAME -d -m sensors

That output has no sensor data in it, where do you see the temperature info? Try clicking the graph and click show rrd command. Pastebin the output.

I created custom group for psSense OS, when I go to devices>group on top of the page there are several tabs ( CPU | Load | Memory | Uptime | Storage | Disk I/O | Poller | Ping | Temperature) when I click on them they show graphs and all are working except Temperature so I was wondering if temperature is even supported for pfSense. Here is rrd command for one of the temperature graphs:

and here is graph address + &debug. I have no idea if this will be any help but here it is:

If you go straight to that device I expect you won’t see temperature. The screen you are on is a bulk screen that shows all that type of graph for devices in the group whether they have it or not.

Thanks for clarifying that :slight_smile:

pfSense is definitely aware of its sys/processor temp, as it shows the temps on its own dashboard screen.

Would be nice if someone could figure out how to get it to report in Librenms. I know people have been asking about this for a long time…


Hi there, we are monitoring a bunch of pfSense devices but haven’t been able to get the Temp through SNMP yet. The main problem seems pfSense not reporting temperature via SNMP. There are many (old) discussion in the forums but none of them actually led to a real solution.

I was able to get the pfSense temps via IPMI. I added the IPMI IP as a server and now can see all the temps along with everything else…
