Node exporter not picking up sensors output and hence sensors metrics are not exported #2986
Description
We are running node_exporter in one of our linux machines and wanted to check the hwmon metrics. But, for some reason sensors data is not being exported.
The VM has a ASUS motherboard. Here is the output of dmidecode

Are you running node_exporter in Docker?
No
What did you expect to see?
I expected to see the node_hwmon_fan_rpm and many other metrics but i don't actually see it.
Running sensors command directly on the VM does show me the FAN and temparature
