Onperf - Physical CPU Monitor producing weird stats.

Hello One and All I have just re-instated onperf as part of my toolkit having at last = upgraded to a version of Online where it once more exists. (Having lost it = in a patch release) It seems that I am getting strange stats from the physical CPU monitor. = It is showing CPU utilisation at wide variance at that reported by mpstat. = To wit; Near 100% utilisation when the CPUs are 80% idle. System time up = to 80% when it never goes over 28% on the mpstat. mpstat results are = validated by sar and vmstat. Has anyone else seen this behaviour. Any ideas? Version is 7.23.uc5, Solaris 2.5 TIA rgds Peter Tashkoff <tashkop@iname.com> Zespri International Limited.
