  1. Experience of xrootd monitoring for ALICE at RDIG sites G.S. Shabratova JINR A.K. ZarochentsevSPbSU

  2. Xrootd Monitoring • Static monitoring - Bdii • Dynamic monitoring – Monalisa and “xRootd federation monitoring”

  3. 2 xrootdBDII versions(from ClaudiuSchiaua ( schiaua@nipne.ro)) • Xrootd information service (xis) 2009 • glite-info-provider-SE_xrootd (gip) 2010

  4. xis • http://niham.nipne.ro/xis/xis.install.html • 2-d xrootd serivce on xis server : root://xishost: 2194 • Xrootd clients on xrootd servers. • Xrootd client on information provider (bdii server)

  5. gip • http://indico.cern.ch/getFile.py/access?contribId=0&resId=0&materialId=slides&confId=77435 • http://niham.nipne.ro/NIHAM-repo/instr.html Xrootd client on gip and bdii server Scheme: GlueSALocalID=xroot:SA             >ClueVOinfoLocalID=xroot:VOID:alice

  6. xrootd in ldap

  7. DPM and xrootd in BDII DPM XROOTD http://gstat2.grid.sinica.edu.tw/gstat/ldap http://gstat2.grid.sinica.edu.tw/gstat/site/RU-SPbSU/treeview/bdii_site/alice23.spbu.ru/

  8. RDIG monitoring http://rocmon.jinr.ru:8080

  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

  14. MonALISA from gui client • GUI client from alimonitor.cern.ch: • Or form http://monalisa.caltech.edu/monalisa.htm :

  15. MonALISA from gui client

  16. MonALISA from console • Need: • Monalisa Repository from http://monalisa.caltech.edu/: • And monalisaWSClients :

  17. MonALISA from console • Result:

  18. xRootd federation monitoring • 17 July 201215.45-16.00ATLAS  Off-Grid  Sites  (Tier-3)  MonitoringA.S. Petrosyan, D.A. Oleynik, S.D. Belov, J. Andreeva, I.S. Kadochnikov (on behalf of the ATLAS collaboration)

  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 GRID'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.

  21. Many thanks: • Sergey Belov • Daniil Oleynik • Artem Petrosyan • Andrey Kiryanov • And etc
