监视终端服务器上的CPU核心使用情况

I have windows 2003 terminal servers, multi-core. I'm looking for a way to monitor individual CPU core usage on these servers. It is possible for an end-user to have a run-away process (e.g. Internet Explorer or Outlook). The core for that process may spike to near 100% leaving the other cores 'normal'. Thus, the overall CPU usage on the server is just the total of all the cores or if 7 of the cores on a 8 core server are idle and the 8th is running at 100% then 1/8 = 12.5% usage.I have windows 2003 terminal servers, multi-cor
