Policing statistics, such as in-profile and out-of-profile octets, are often an important mechanism for evaluating the effectiveness of installed policies. In order to track these statistics, additional system resources are consumed meaning that the amount of filters available for classification purposes is limited. Setting this object to 'true(1)' causes statistics to be tracked by default for all metered policies defined after this attribute is set. A value of 'false(2)' means that new metered policies will not track statistics. Note that this attribute specifies the default behavior. Statistics maintenance may be enabled and disabled on a per policy basis via an attribute in the ntnQosTargetStatsTable. If a value for that attribute is not provided, the value of this object determines the behavior.
