I have confirmed this simple unit change works fine with following step:

  1. Run cat /dev/urandom | gzip -c > /dev/null as many as the number of cores (it was 4 here)
  2. Confirm (sum(irate(node_cpu_seconds_total{}[5m])) - sum(irate(node_cpu_seconds_total{mode="idle"}[5m]))) reports similar number as above (was completely same to 4 in grafana dashborad)
  3. Kill one of those processes and confirm it decrease around 1
  4. Do 3 until no 2's processes alive

Fixes: #1129

@stuartnelson3 Could you confirm whether this still works on your system? In that case I'd merge this.
