well you would use a system monitoring platform primarily. do you now already poll these details every minute or so as standard? I'd suggest a system like hyperic or nagios to do this.

because I execute remotely and the system monitor does not support external network. So I want to do it in ssh client.

well it'd have been helpful to have said that... you might want to look at dssh, or if you install pexpect, there is a useful demo tool in there I use called hive.py which will log into a list of clients and run the same command on all at the same time.
