I need to find the following information of IBM Power8 running Linux:

  1. Processor type
  2. Model Name
  3. Processor speed

Following is the required output (came from another source called BigFix) :

"IBM(R) POWER8(R) MODEL 9009-42A REV 2.1 @ 3026.000000MHZ RUNNING AS POWER8"

I have tried different commands but nothing returns such output. Following are the commands I have tried so far :

  1. dmidecode
  2. lshw
  3. /proc/cpuinfo
  4. lscpu
  5. unman -a
  6. ppc64_cpu

    Instead of "size", you might have meant "speed"?

  • yes exactly "speed". Thanks for correction. Jul 16, 2019 at 12:27
  • I've edited your question to change "size" to "speed". You're also able to edit your question, as needed.

You could use the nmon.

By opening nmon and then use the r option for Resources Linux & Processor will provide the information for CPU. Note that nmon needs to be installed separately as its not out of the box utility in Linux.
