Assessing a Central Satellite Data Repository and its Usage Statistics

STAR Central Data Repository (SCDR) collects a large volume of real-time and near real-time satellite data to improve data management and facilitate research and development activities across the organization. How to track and showcase the usage of this system using formal metrics is still challenging, and is very useful and helpful to better manage data, monitor system status, evaluate program output, and plan future infrastructure. This paper proposes design and implementation of a metrics analysis system to collect metrics information on user data requests, manage and organize request information, and represent metrics information in an intuitive and interactive manner. The system offers detailed information on satellite data product requests from users on various hosts and robust capabilities of generating insight charts and periodical report.
