SAR command in Shell for Media Server CPU real-time utilization

[telecomPA]

hi all, a while back someone i worked with showed me how she could see real-time CPU utilization of one of our PBX's. i asked her what the command was and she gave me the following:

sar -u -f sa20

the SAR command shows CPU utilization
the -u parameter is for utilization
the -f paramteter is for file name
the sa20 is the file name

so the command works, but it's a log, not real-time information. does anyone here know how to view CPU utilization on a S85xx or S87xx server?

thanks in advance.
