Temp graph problem


On of my switches (cisco 2960xr) in an outdoor enclosure just dipped to -1 C when checked from the console. Librenms graphs this as 255 C. Not sure if there is a config somewhere that I need to edit or this is a bug.

Make sure your daily.sh cron is running and run ./daily.sh by hand to see if there are any errors.




Please, run ./poller.php -d -h affectedhost -m sensors and check output for that sensors/pbin here.

You can use https://p.libren.ms for that


Output is here . Unfortunately when I ran this command the temperature has crept back up and is now a brisk 8C out so it isn’t currently reporting 255.


Then we cant do nothing. Next time, if you see it on time, do the same command to check output


Thanks for your attention, if it does it again I will make sure to run that command and update this post.
