Lower the number, better it is (always).. but i wouldnt be alarmed to see CPU utilizations from 20-50 % ... On older switches like 2900 XL & 3500 XL I think the CPU is always more than 50 %, even in normal circumstances....
With new switches which are highend, you can see much lower CPU instances.. We normally configure the network management system to throw an alert say after 70 % ... again, we are looking at a longer duration for CPU spikes, and not a 1 sec interval ! It again is based on what type of traffic your router/switch runs, and if the device was properly positioned for that particular task..
I would baseline the CPU utlization of the devices, and see what the acceptable levels are for devices,... report the baseline cpu for a month, and then configure NMS systems accordingly... anything over 50 % i would definitely have a look at what process is taking up the CPU, especially on core switches and highed edge components..
