Question: Why I always get CPU core 3/4 as 100% usage when using standard MIB?

Answer: The utilization values ​​for cores 3 and 4 obtained using the standard MIB do not represent their true utilization. Currently, the Zyxel proprietary MIB is required to obtain the average utilization of the fast-path CPUs (cores 3 and 4).
