I am not aware of such tool. It is a good idea to report p50, p90, p99, p99.9 for CPU utilization but I also think it is good to report avg as well. Application performance issues should be monitored from the app point of view (response latency) and if you have that you can drill down and pin point CPU issues. Generally speaking it is better to monitor metrics from upper layers than just look at OS graphs. Most of the monitoring systems cover these in one dashboard so you can easily track down issues.
