How do you guys troubleshoot high CPU utilization on the ASR-9K platform? Detailed guides are available for IOS platforms, but I can't seem to find anything useful for the ASR. The average line-card (0/0/CPU0: A9K-24x10GE-TR) CPU utilization of my routers is about 10%, however recently I have noticed that 3-5 times a day it increases to 40% and stays there for about an hour (20% spp + 10% netio + the rest). I know this is well withing the acceptable range, but I am the kind of person who likes to understand every change in his network and during the investigation I had to realize that I simply don't have the tools to troubleshoot the ASR CPU.
