[R] Reg : R : How to capture cpu usage, memory usage and disks info using R language

[Manohar Reddy]

Thanks Jim.



   Actually my requirement is I have ~ 20 servers which are running on
windows server family OS,if I want to check any server cpu usge,memory
usage or disk info I need to log into every server instead of doing like
this if I  get that kind of information using R then I can save it in some
RDBMS database then I will populate this live data on some dashboard like
which are made by R using shiny,so that I can view/get the all the
information on single page.



   Here for me challenging work is how to capture cpu,memory,disk info
using R .
