This read-only PerfCounter64 counts Frames Marked Green by this QoS policer, meaning frames that conformed within the committed rate and were passed without penalty. A healthy green count relative to total input tells an administrator how much of a customer's traffic is running within its contracted rate. For example, an operator verifying a service level agreement would check that cmQosPolicerV2StatsFMG accounts for the vast majority of frames during normal, non-bursting hours.
