Data Volumesince June 2012
Data are split into 3 schemas FTS, XRootD (AAA and FAX) High optimization (Partition, no Global indexes, …)

Data Volumesince June 2012
# ROWS (million) Space (GB)FTS 648 (+7.2/day) 274 (+3/day)
XRootD (incl. local accesses) 2,283 (+4.2/day) 636 ( +1.2/day)
Data are split into 3 schemas FTS, XRootD (AAA and FAX) High optimization (Partition, no Global indexes, …)

Snapshot on Tuesday 11 Feb 2014 Shows the usage of the DB at this specific time No conclusion can be drawn on technology usage
See next slide on data retention policy
12 February 2014Alexandre Beche – GDB
16IT-SDC
Data retention policy Two kind of data:
Raw: Kept for 3 months for FTS Kept indefinitely for AAA and FAX
Statistics: Different granularity (10 minutes, daily) Less than 50GB of data Kept indefinitely
12 February 2014Alexandre Beche – GDB
17IT-SDC
Main improvements
ALICE traffic is now included No more duplication at the raw data
level WLCG view is an aggregation over APIs
FTS Dashboard is much faster Does not have the XRootD overhead
Long time period can be queried See next slide

Activity since June 2012
Impossible with the old architecture
19IT-SDC
Future work Improve the integration of
technology specific dashboards
12 February 2014Alexandre Beche – GDB
20IT-SDC
Future work Integration of the map view
Already available for AAA, FAX and FTS

Application usageincluding WLCG Home page
12 February 2014Alexandre Beche – GDB
22IT-SDC
Summary Completely new architecture
Greater flexibility Easier integration of heterogeneous data
Optimized technology-specific dashboards Aggregated together inside a top level UI
Thanks for your attention
