9. Requirements to dynamic monitoring Transfers details: – Host out (ip) – Host in (ip) – Size of file – Number of files Statistic details: – Size of packages for host out (in) by time – Errors

18. xRootd federation monitoring 17 July 2012 15.45-16.00 ATLAS Off-Grid Sites (Tier-3) Monitoring A.S. Petrosyan, D.A. Oleynik, S.D. Belov, J. Andreeva, I.S. Kadochnikov (on behalf of the ATLAS collaboration) ATLAS Off-Grid Sites (Tier-3) Monitoring

19. Data flow for XRootD Both summary and detailed events gatherer implemented as Linux daemon Summary data goes directly to Ganglia File transfer data can be stored in local PostgreSQL and then presented via Ganglia Detailed data can be delivered to ActiveMQ directly Data being sent to global level: Domain from, host and ip address Domain to, host and ip address User File, size Bytes read, written Time transfer started and finished 1917.07.2012GRID'2012, JINR, Dubna

20. Conclusions: Bdii monitoring works, but not supported and rarely used Monalisa monitoring works, but can not monitor separate transfer “xRootd federation monitoring” – we wait it in the near future.
