The value of object tmnxBsxAaSubUsageMonTable specifies an entry for each Application-Assurance subscriber for each statistics type within a group, partition and statistics interval. Each row contains the Application Assurance usage monitoring statistics collected for the subscriber, based on configuration in tmnxBsxStatAaSubCfgTable. Entries are based on Policy and Charging Control (PCC) rules received from the policy server which contain subscriber, and statistic type/name information. A subscriber is uniquely identified by a tmnxBsxAaSubscriberType and tmnxBsxAaSubscriber. The typical usage of this table is to fill in the part of the index that identifies a subscriber (tmnxBsxAaGrpPartIndex, tmnxBsxAaSubStatsInterval, tmnxBsxAaSubscriberType and tmnxBsxAaSubscriber), and perform a partial walk to retrieve the usage information. In order to prevent real-time issues, an SNMP get next request which results in a change in subscriber will return not-found.
