Cisco 1841 High CPU doest not match with the sumary at top

[pmartinez4191]

Hello,

I have a problem with a cisco router 1841, it has a hight cpu and I'm trying to troubleshooting, i used the "show processes cpu sorted" command but it shows a result that i don't understand.

The sum of the calues doest not match with the sumary at top, I attach an image.

Any suggestions?

Hello @pmartinez4191 ,

I/O interrupts are shown only for 5 seconds CPU and it is the second number after 78/55. You have 55% of I/O interrupts

The difference can be seen as the effect of I/O interrupts this gives you a direction for further troubleshooting
