Solutions

1. Check that the platform supports sensor readings via gopsutil (temperature sensors are unsupported on Windows and the BSDs).
2. Ensure required kernel modules for hardware monitoring are loaded (e.g. 'modprobe coretemp' or 'k10temp' on Linux).
3. Verify the process has permission to read /sys/class/hwmon entries.

When it happens

Trigger: Occurs when reading sensor values from the hwmon sysfs entries fails, e.g. permission errors or sensors disappearing after suspend/resume.

Common situations: Running without read access to /sys/class/hwmon, on virtualized hardware, or when the kernel unloads a sensor module.
