Glances' sensors plug-in: “No such file or directory: '/sys/class/hwmon/hwmon0/device/name'”

[Franck Dernoncourt]

I use Glances (mirror) to monitor on my computer (Ubuntu 14.04.5 LTS x64 + Glances==2.8.5).

After installing the sensors (mirror) plug-in, I get this error message whenever I tried to run sudo glances:

mlee@server:~$ sudo glances
Traceback (most recent call last):

    return open(fname, "rt", **kwargs)
IOError: [Errno 2] No such file or directory: '/sys/class/hwmon/hwmon0/device/name'

I tried:

sudo apt-get install -y lm-sensors
sudo apt-get install -y hddtemp
sudo pip install PsUtil

It didn't help. What do I need to do so that /sys/class/hwmon/hwmon0/device/name contains something that satisfies glances?

Upgrading to the latest version Glances==2.8.8 did not help.

Thanks,

It's a PsUtil issue, try to upgrade it:

# pip install --upgrade psutil
