Eu tenho um arquivo que contém 2 saídas de tempo médio de carregamento e & Coluna% da CPU como uma saída do comando superior.
Então, é possível calcular isso na utilização da CPU ou no uso da CPU por vez?
Exemplo:
=====================================================================
APPLIANCE CPU USAGE
=====================================================================
0.90 1.05 0.84 1/151 13615
=====================================================================
APPLIANCE PROCESSES
=====================================================================

Você pode calcular cpu% com o seguinte código:
#!/bin/bash
FILE=<file path>
CPU_USAGE='sed -n 'H; /^USER/h; ${g;p;}' $FILE | awk '{print $3}' | awk '{sum+=$1} END {print sum ;}''
CPU_CORES='nproc --all'
ACTUAL_CPU_USAGE='echo "$CPU_USAGE $CPU_CORES" | awk '{print $1/$2"%"}''
echo "CPU : $ACTUAL_CPU_USAGE"
