Xrootd Monitoring
• Static monitoring - Bdii
• Dynamic monitoring – Monalisa and “xRootd
federation monitoring”
2 xrootd BDII versions
(from Claudiu Schiaua (

• Xrootd information service (xis) 2009
• glite-info-provider-SE_xrootd (gip) 2010

• 2-d xrootd serivce on xis server :

• Xrootd clients on xrootd servers.
• Xrootd client on information provider (bdii
server)

RDIG monitoring

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

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)
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:

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.
