This read-write TruthValue enables or disables the in-profile/out-of-profile packet counters for this metering class entry. An admin turns this on when they want visibility into how much traffic a metering class is passing versus penalizing, rather than just enforcing the rate silently. For example, an admin diagnosing whether a rate limit is too aggressive for a given application would enable this counter to see the split between in-profile and out-of-profile traffic volumes.
