The value of object tmnxBsxAaSubUsageMonEntry specifies an entry which stores the Application Assurance usage monitoring statistics for a combination of group, partition, statistics interval, subscriber, statistics type, and statistics name. An entry is added when a new rule is sent from the policy server. As protocols are not supported by Application Assurance usage monitoring, the tmnxBsxStatAaType value of 'protocol (1)' will never appear as part of the index. As only snapshot statistics collection is supported by Application Assurance usage monitoring, the tmnxBsxAaSubStatsInterval value of 'snapshot (2)' will always appear as part of the index.
