Abstract: A network device may receive one or more packets, and may determine a flow control parameter, a rate limiting parameter, and a statistical sampling parameter associated with a slow counter. The network device may determine whether the flow control parameter satisfies a first threshold, whether the rate limiting parameter satisfies a second threshold, and whether the statistical sampling parameter satisfies a third threshold. The network device may identify a counter event associated with one of the one or more packets, and may selectively assign the counter event to a fast counter when at least one of the first threshold, the second threshold, or the third threshold being satisfied, or to the slow counter when none of the first threshold, the second threshold, and the third threshold being satisfied.
