Monitor individual CPUs in a SUN-Fire

I have been asked to monitor the individual CPUs within a SUN Fire 4800. The system has 12 CPUs and the DBAs are saying that some are being hammed!

The DBAs bind informix processes to an individual CPU.

I have used "sar" to collect some details so far, but the data collected is treating the 12 CPUs as a single resource and not showing what is happening to the individual CPUs.

So far "sar" doesn't show a problem with an individual, because if one or two CPUs are being hammed it will be only a small dip! beacuse the other CPUs are ok.

Is there are way to monitor the individual CPUs on a Solaris 9 system.

Thanks
