A grid accounting report, showing resource usage/allocation by site and experiment, is produced each month, integrated into a report for the current calendar year. Reports consist of data on CPU, Disk and Tape.
Grid Accounting Portal
The EGI Accounting Portal collects all accounting data for the whole of WLCG (US, Europe etc). All of our accounting reports are extracted from this portal.
Reports
All reports (Tier-1 & Tier-2) are stored in the WLCG Document Repository.
Generating the reports
Data snapshots of the previous month are retrieved into CRIC from the EGI accounting portal and WLCG Storage Space Accounting applications around 10th of the month. The request for accounting validation is announced to the WLCG community, whereby site administrators are asked to check auto-generated data and submit corrections via CRIC validation UI. Reports are generated towards the end of the current month for the previous month.
The report is calculated by combining:
- CPU data from the EGI Accounting portal
- Disk and tape data from the WLCG Storage Space Accounting application (WSSA)
