High-level service architecture
Resource centres that provide compute or storage to the infrastructure have a collector (a stand-alone script or program, or a built in function of their resource system) that gathers accounting metrics formatted into a standardised record format. These metrics are then transferred via a messaging service to the Accounting Repository, which stores and processes the data to produce aggregations that are then sent to the Accounting Portal for display.
The Accounting Portal retrieves topology information on how resource centres relate to national infrastructures and regions from a configuration management database (CMDB) and community affiliation from the AAI service to properly organise the accounting data. Information related to groups or VOs should also contain information about scientific disciplines to allow the Portal to properly classify the resource usage.
Resource centres can either directly publish accounting information to the central Accounting Repository or via an intermediate repository that can be related to an infrastructure (European, regional or thematic etc.).
