- Service name: Accounting Repository
- Service category: Operations
- Service type: Coordination, operation and maintenance
The Accounting Repository is part of the EGI Core Infrastructure Platform which supports the daily operations of EGI.
Introduction
The EGI Accounting Infrastructure is distributed. At a central level it includes the repositories for the persistent storage of usage records. The central databases are populated through individual usage records published by the Resource Centres, or through the publication of summarised usage records. The Accounting Infrastructure is essential in a service-oriented business model to record usage information.
Technical description
The Accounting repositories store CPU, cloud and storage accounting data collected from sites participating in the EGI and other external infrastructures supporting international EGI user communities. The accounting information is gathered from different sensors in to central accounting databases where it is processed to generate statistical summaries that are available through the EGI Accounting Portal. The Accounting Repository is based on the APEL software, has a MySQL database backend and collects usage records through the EGI messaging infrastructure (ActiveMQ) by means of the Secure Stomp Messenger protocol.
The central accounting repository is capable of collecting usage records for compute, storage, and cloud resources.
