•
<sensor>_label
contains a description of the sensor
•
<sensor>_input
contains the current value of the sensor, in thousandths of the base unit
(°C, V or A)
•
<sensor>_max
contains the warning maximum threshold for the sensor, in thousandths of
the base unit (°C, V or A)
•
<sensor>_min
contains the warning minimum threshold for the sensor, in thousandths of
the base unit (°C, V or A)
•
<sensor>_crit
contains the critical maximum threshold of the sensor, in thousandths of
the base unit (°C, V or A)
•
<sensor>_alarm
contains
1
if an alarm condition exists for the sensor, else
0
.
Read the
<sensor>_label
files to determine the files correspond to a given sensor. For
example:
$ cd /sys/class/hwmon/hwmon1/device
$ grep -HT . *_label
curr1_label: 12V PCI
curr2_label: 3V3 AUX PCI
curr3_label: 3V3 PCI
curr4_label: VCCINT OUT
in0_label: VCC0V85
in10_label: 3V3 PCI
in11_label: VCCINT OUT
in1_label: VCC1V8
in2_label: 1V2VCCO
in3_label: 1V2AVTT
in4_label: 0V9AVCC
in5_label: 3V3
in6_label: 3V3 CAGES
in7_label: 5V0
in8_label: 12V PCI
in9_label: 3V3 AUX PCI
temp1_label: Tdiode (FPGA)
temp2_label: Ambient (FPGA)
temp3_label: Ambient (left)
temp4_label: Ambient (right)
temp5_label: VCCINT
Note: The sensor names in these files are the same names that are output by the
sensors
command. See
Getting Output for a Specific Device
.
Then read the appropriate set of files to get information for a particular sensor. For example, if
you wanted to get information about the ambient temperature sensor for the FPGA, the previous
output shows that this information is in the
temp2_*
files, and so:
$ cd /sys/class/hwmon/hwmon1/device
$ grep -HT . temp2_*
temp2_input: 48000
temp2_label: Ambient (FPGA)
temp2_max: 0
temp2_min: 0
