lmsensors for Monitoring a Hetzner EX41 with nct6775 on Centos7

Hi,

I recently rented a new Hetzner Box to replace my old. I moved from EX40 to EX41 and saving even some money every month :-).

Every thing went smooth, but the sensors did not work. I had to use nct6775, but the module from Centos7 said “No Device”. ElRepo to the rescue. They have a nct6775 kmod available, but this module is not compatible with Centos7.4 :-(.

First I had to created a fixed package. I changed only the release-number and the kversion to¬† 693.2.2 instead of 327. The fixed version is available at: https://www.kuehnel.org/nct6775/. I also open a ticket with elrepo: https://elrepo.org/bugs/view.php?id=792. I don’t know how they will fix this. ElRepo uses kABI-tracking kmods and things like that should not happen. We will see.

With this fixed package installed I created the following configuration file (/etc/sensors.d/hetzner) with the help of sensors -u:

chip "nct6792-*"
 label in0 "2V"
 label in2 "3.3V1"
 label in3 "3.3V2"
 label in6 "1V1"
 label in7 "3.3V3"
 label in8 "3.3V4"
 label in9 "1V2"
 label in12 "1.1V"
 label fan1 "fan"

 set in0_min 2 * 0.80
 set in0_max 2 * 1.2
 # Can not set alarms
 #set in0_alarm: 0.000

 # SYSTIN
 set temp1_max 40
 set temp1_max_hyst 38
 # CPUTIN 
 set temp2_max 40
 set temp2_max_hyst 38
 # AUXTIN0
 #set temp3_input 40
 # PECI Agent 0
 #set temp7_max 40

 ignore in1
 ignore in4
 ignore in5
 ignore in10
 ignore in11
 ignore in13
 ignore in14
 ignore fan2
 # AUXTIN1:
 ignore temp4
 # AUXTIN2:
 ignore temp5
 # AUXTIN3:
 ignore temp6
 # SMBUSMASTER 4:
 ignore temp8
 # PCH_CHIP_CPU_MAX_TEMP:
 ignore temp9
 #PCH_CHIP_TEMP:
 ignore temp10

 ignore intrusion0
 ignore intrusion1
 ignore beep_enable

I can not fix the alarm for 2V (in0), but the rest looks good. Don’t forget to set the setting with sensors -s.

Update 15.10.2017: The module kmod-nct6775 is now update in elrepo directly, so only the configuration file is needed.
