Prerequisites for using AMS

  • A valid host certificate from an IGTF Accredited CA.
  • A GOCDB 'Site' entry flagged as 'Production'.
  • A GOCDB 'Service' entry of the correct service type flagged as 'Production'. The following service types are used:
    • For Grid accounting use 'gLite-APEL'.
    • For Cloud accounting use 'eu.egi.cloud.accounting'.
    • For Storage accounting use 'eu.egi.storage.accounting'.
  • The 'Host DN' listed in the GOCDB 'Service' entry must exactly match the certificate DN of the host used for accounting. Make sure there are no leading or trailing spaces in the 'Host DN' field.

Monitoring of the accounting data

To ensure the monitoring of the publication of the accounting data, one CE per site needs to be registered as "APEL" service endpoint.
