This Counter64 field reports the bytes received per second on the forward direction of this bidirectional CES tunnel, as computed for this PM instance. Because this TotalStats row has neither a clear-time nor a Duration/State field — it is the true lifetime, never-reset total for this PM instance since it was provisioned, and this specific field is an instantaneous computed rate of accepted ingress traffic rather than a running total, so it reacts immediately to a burst instead of waiting for a bin to close, it is the field to check when you need to see the forward-direction ingress throughput of the tunnel right now rather than a cumulative volume. For example, this counter might read 7,712 bytes/sec during the lifetime of this PM instance — a sudden jump to several times that on the forward side, with no matching rise on the other direction, would point to a one-way traffic surge or an attack riding that leg of the tunnel.
