This counter reports the total bytes of ingress traffic on this PM instance that exceeded even the excess rate and were outright discarded, during today's still-accumulating 24-hour window. Any nonzero value accumulated over today's still-open 24-hour bucket represents traffic this specific service actually lost at ingress due to rate policing, which is a direct, quantifiable cause for a customer's throughput or application-quality complaint on this port, distinct from congestion elsewhere in the network. For example, if this counter shows 50,000 dropped bytes within today's still-open 24-hour bucket right when a customer reports a large file transfer stalling, that strongly suggests their traffic burst past the service's excess rate rather than the file server itself being at fault.
