Xrootd monitoring status update(Data collectors and Dashboard)
Julia Andreeva on behalf of xrootd monitoring developers:
Matevz Tadel, Artem Petrosyan, Daniel Dieguez Arias, Sergey Belov, Danila Oleynik, Domenico Giordano, Sergey Mitsyn, David Tucket, Alexandre Beche

Changes in the UCSD collector
• Matevz had created the new version of the collector which does publishing to ActiveMQ. In future no need for an additional component which does translation of UDPs into ActiveMQ reports.
To be done:• Crosscheck that data reported by the old and new
versions is consistent (Domenico Giordano)• New version has to be tested and properly
packaged (Sergey Belov, estimated time ~2 weeks)

Dashboard Message Broker and ActiveMQ collectors
• Tadashi confirmed today that he could consume from the xroot-related topics via virtual queues
• New Dashboard collector consuming xrootd messages (old collector) had been developed ( Daniel Dieguez Arias). For the moment data is recorded in the Dashboard Integration DB (ORACLE).

Topology
• Topology information for the moment is created manually. Server/client domains from the xrootd reports are manually maped to sites as they are defined in OIM/GOCDB. Used information sources : VO topology feeds and information from the CMS and ATLAS Dashboards
• Looking forward when this mapping will be provided by AGIS

Xrootd traffic in the WLCG Transfer Dashboard
• Thanks to Daniel Dieguez Arias the first prototype showing both FTS and xrootd traffic is available:

clear how we can do it. Investigate various possibilities (subscribe to UCSD ML repository or using Gratia reports)
