How to get CPU utilisation, RAM utilisation in MAC from commandline

Question

I know that using Activity Monitor we can see CPU utilisation.But i want to get this information of my remote system through script. top command is not helpful for me. Please comment me any other way to get it.

Answer 1

What is the objection to top in logging mode?

top -l 1 | grep -E "^CPU|^Phys"

CPU usage: 3.27% user, 14.75% sys, 81.96% idle 
PhysMem: 5807M used (1458M wired), 10G unused.

Or use sysctl

sysctl vm.loadavg
vm.loadavg: { 1.31 1.85 2.00 }

Or use vm_stat

vm_stat
