US Patent 10305761 Multi-application SaaS metering engine

An accurate monitoring system for a multi-tenant system monitors each data stream of the multi-tenant system and determines the identity of the tenant using each of the data streams, and the application that the tenant is accessing. Aspects of each data stream are aggregated by a bucket aggregator to track and record trends for each tenant and/or each application. The aggregated data could be filtered, sorted, and reported for accurate subscription billing for each of the tenants and/or applications within a multi-tenant system.
