10 thoughts on - Versions In RHEL And CentOS

• No, that is 8.0.2 .. which is older than 8.1.

  RHEL has several updates within the point release cycle that are just normal updates .. we push those as well, but we don’t use the 3rd digit.

• Hi,

  Thanks for the information

• …

  Curious what “sensors” you are referring to..

  Like this:

  $ cat /sys/devices/system/cpu/online
  0-63

  or this:

  $ lscpu | grep CPU\(s\)
  CPU(s): 64
  On-line CPU(s) list: 0-63
  NUMA node0 CPU(s): 0-15,32-47
  NUMA node1 CPU(s): 16-31,48-63

  or what?

• Hi Peter,

  /usr/bin/sensors

  from the lm_sensors package

  I had run

  sensors-detect –auto

  before running sensors

  thanks.

• why not use dmidecode ipmi,  things like that?

• sensors

  gives the temperature of each core if the CPU is supported.

• …

  I had no idea people still used that package. Especially on a server.

  Per core temperatures in linux for Zen2 is done using (a very up to date kernel with its k10temp module). Alternatively one can look at:

  https://github.com/ocerman/zenpower.git

  I don’t know if it works with the c8 kernel (but it does not work with the c7 one).

  But in the end. Why care about per core temperatures? Setup basic monitoring of the server using ipmi or whatever the vendor supports.

• Hi Peter,

  Is it due to some security issue ?

  We install on all our machines (servers/desktops).

  thanks.

• Not security but safety (and also, it’s not needed when there are supported ways to get that data and better).

  By safety I refer the half-blind scanning of smbus etc. that sensors-detect does.

  To me it feels like a relic from desktops 15 years ago :-)

• Hi Peter,

  Ok.

  I will look for alternatives.

  Thanks for the information.

  thanks.
