Hello all,
I have a CPU process problem, the total five minutes CPU is showed 30%. But after I sum all processes, 5Mins is only 1.74, 1Min is 2.05, and 5Secs is 3.43. It is lower than 30%. It is very confused me. What process take use the rest CPU 28% (30%-1.74%)? How to show it out?
The router platform is 7204VXR (NPE225), version Version 12.4(18). Normally the traffic is between 10Mbps to 20Mbps.

Hello Jeffery,
the show cpu takes in account also cpu usage caused by interrupts:
CPU utilization for five seconds: 34%/31%; one minute: 31%; five minutes: 30%
you see 34%/31% the 31% is caused by interrupts.
if this is a software based router this can be normal and related to traffic volume.
for this reasons the sum of cpu usage caused by processes is so low in comparison to total cpu usage over time
Hope to help
Giuseppe
