Apparatus and method for monitoring and metering

PURPOSE: A monitoring and metering device and a method thereof are provided to offer a monitoring and metering service based on the existing application, thereby minimizing time, man power, and expenses necessary for converting the existing application into a cloud computing service type and offering the monitoring and metering service. CONSTITUTION: A collection unit(150) collects monitoring and metering data generated in a multi-tenancy environment. A first storage unit(110) stores first meta-information ID and the monitoring and metering data by mapping the same. The first meta-information ID represents first explanation information which explains attributes of the monitoring and metering data. A second storage unit(120) maps and stores explanation information with different attributes and meta-information IDs assigned to the explanation information. When the first meta-information ID is stored in the second storage unit, a controller(160) maps the first meta-information ID and the monitoring and metering data and stores the same in the first storage unit.
