How to get CPU usage and RAM usage without exec?

by

Use PHPSysInfo library

phpSysInfo is a open source PHP script that displays information about the host being accessed. It will displays things like:

  • Uptime
  • CPU
  • Memory
  • SCSI, IDE, PCI
  • Ethernet
  • Floppy
  • Video Information

It directly parsed parses /proc and does not use exec.

Another way is to use Linfo. It is a very fast cross-platform php script that describes the host server in extreme detail, giving information such as ram usage, disk space, raid arrays, hardware, network cards, kernel, os, samba/cups/truecrypt status, temps, disks, and much more.
