Go back to the activity list.

  • 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.

This service includes the following components.

Coordination

This activity is responsible of the coordination of the APEL database operation and upgrade activities with those partners that are in charge of operating other systems that depend on the central APEL accounting databases.

Support

Support during business hours about the accounting records publishing process in the production infrastructure. Support is provided to the operators of those infrastructures that publish or need to publish usage records into the EGI central accounting databases (Resource Centres, NGIs and other integrated and peer infrastructures). Support about APEL parsers and publishers is out of scope and is part of activity 2nd level support (core platform).
