AB: The Earth Observing System Data and Information System (EOSDIS) and related data centers have been collecting and analyzing information on the archiving, processing and distribution of Earth science data for more than 10 years. Long-standing approaches for evaluating the performance of systems managed by EOSDIS have provided insights into how system engineering requirements are being met, how user communities are being served and the levels of interest across the science data products. However, data and services are increasingly being made available to users via web-based applications that cannot be evaluated with current methodologies. New tools are required to record and analyze how users find, navigate and use the continuously evolving landscape of web-based resources supported by EOSDIS. Without such tools a significant portion of the data and services EOSDIS provides would not be captured. EOSDIS will be able to incorporate metrics collection on new web-based applications across geographically distributed and differently configured systems while not interfering in those systems' operations. A consistent process has been devised for collection and reporting of information on web data usage and the characterization of the community of web service users. To provide a more complete picture of system utilization, knowledge of the web resource usage is coupled with improvements to the current approaches for collection of processing, archival and distribution metrics of Earth science products. This combined information improves evaluation of engineering requirements and understanding of how the new web capabilities are impacting usage and distribution of science data and services provided by EOSDIS. This paper describes the new, non-intrusive methodology EOSDIS is using to capture and analyze information on the usage of web services across all related systems. The paper will discuss initial results demonstrating the benefits of the reengineered system.
