[[Category:Accounting]]
  
APEL parses batch system and Grid gatekeeper logs at each Grid site to generate CPU usage records and publishes them into a centralised repository at a GOC (Grid Operations Centre) using ActiveMQ or RGMA as the transport mechanism. The records are processed and summarised and can then be accessed through the [[Accounting_Portal|Accounting Portal]].

APEL is an accounting tool that collects accounting data from sites participating in the EGI and WLCG infrastructures as well as from sites belonging to other Grid organisations that are collaborating with EGI, including OSG, NorduGrid and INFN.
  
The EGEE/WLCG Accounting service is comprised of data collection and reporting services, is a large centralised database which collects and aggregates CPU usage information from sites across the Grid through different types of sensors. It is described in https://edms.cern.ch/document/726137 .

Description

APEL is an accounting tool that collects accounting data from sites participating in the EGI and WLCG infrastructures as well as from sites belonging to other Grid organisations that are collaborating with EGI, including OSG, NorduGrid and INFN.

The accounting information is gathered from different sensors into a central accounting database where it is processed to generate statistical summaries that are available through the EGI/WLCG Accounting Portal.

Statistics are available for view in different detail by Users, VO Managers, Site Administrators and anonymous users according to well defined access rights.
