CKA study material · question 468 of 1000

Node Problem Detector does not recognise a node's kernel messages. Why?

  1. It reads the kernel log format and a different format needs an extension
  2. It ignores kernel logs by design
  3. It only runs on control-plane nodes
  4. It requires the systemd journal
Show the answer

Answer: A. It reads the kernel log format and a different format needs an extension

Node Problem Detector uses the kernel log format, so another format has to be added to be understood.
