I´m looking for a Solaris command to see which process are exhauring
system´s cpus. In my job I use a sunfire 6800 (12 cpu´s). Any times,
when I issue iostat 1 4, ID column shows me:

ID
4
3
5
8

I´d like know which process are exhauring system´s cpu resources.
How could interpret prstat -a 1 output ?
Which another command could I issue to fetch informations about the
most cpu´s consumer process ?
Thanks in advance...
