Getting Output for a Specific Device
Then, to get output for a specific device pass its name to the sensors command. For example, for
the Ethernet controller named
xilinx_efct-pci-0100
:
$ sensors xilinx_efct-pci-0100
xilinx_efct-pci-0100

3V3 PCI: +3.31 V (min = +3.00 V, max = +3.60 V)
VCCINT OUT: +0.90 V (min = +0.00 V, max = +0.00 V)

VCCINT OUT: +16.50 A (min = +0.00 A, max = +0.00 A)
Reading Sensor Values from the Filesystem
Sensors for Linux devices output their values into the
/sys/class/hwmon
hierarchy, in a
directory named
/sys/class/hwmon/hwmon<n>/device
.
To determine which of the
hwmon<n>/device
directories contain sensor data from the X3522
card, search for a
driver
file within the directory that is a soft link to the
xilinx_efct
driver:
$ for dir in /sys/class/hwmon/*/device
> do
> readlink $dir/driver | grep -Eq '/xilinx_efct$' && echo $dir
> done
/sys/class/hwmon/hwmon1/device
/sys/class/hwmon/hwmon2/device
/sys/class/hwmon/hwmon3/device
/sys/class/hwmon/hwmon4/device
So in the above example, the four directories
/sys/class/hwmon/hwmon1/device
to
/sys/
class/hwmon/hwmon4/device
(inclusive) contain sensor data from adapters using the
xilinx_efct driver.
Within these directories, each sensor has the following files:
