On the other hand, for us it was a problem.  our mx450's were showing 100% utilization and we were killing it.  It even caused it to reboot until we offloaded dns traffic.   I wouldn't say they're 100% accurate but I wouldn't say they should be ignored either.  Kinda like the lights on your vehicles dash.      Many factors go into your utilization and cpu score is driven by packet processing (ids/ips) and anything the mx is routing.  Most important is not to exceed your maximum number of flows.. (thus why we had to offload dns)
