Outreach
- CHEP paper - received comments (https://indico.cern.ch/event/1338689/papers/6010796/)
- Paper is at https://www.overleaf.com/read/jwwxfcqcpqqs#3ae27b
- Scitags roadshow: Tim gave a talk at GEANT SIG-NOC last week and GNA-G Europe this week; next talk is at GNA-G US on Thursday
- ISE submission - we agreed to extend the draft before re-submitting
- Plan to update our web page
Collectors
- Missing Kafka input/output plugin (A: Andy Lake)
- Meeting with GEANT dedicated to collectors will be this Thursday
- Reaching ESnet collector from RAL doesn't seem to work (and is not easy to debug)
- For now I have offered CERN site collector as intermediate, but having UK collector up and running soon would be great
- Added monitoring to CERN site-collector to understand the workload (uses logstash exporter/prometheus and grafana)
Registry
- Setup new API at https://scitags.docs.cern.ch/api.json (based at CERN, to be used by WLCG experiments and their storages)
- This URL is used to configure fallback mechanism in xrootd, so in principle all WLCG storage nodes can access it
- The previous access http://api.scitags.org still works and is in sync with the CERN one (points to Github)
- Will keep running both for the time being
Dashboard (@ESnet)
- Following CMS xrootd configuration campaign we now have some sites sending fireflies but not showing up in the dashboard (CNAF, RAL)
dCache
- Submitted two PRs - both were accepted
- Support for sending fireflies, parsing information from xroot/http protocols
- Also implemented fallback mechanism (if no information in xroot/http) - based on x509 VO (user certificate)
- Currently working on adding stats: usage (bytes sent/rcvd) and storage technology statistics (read/write bandwidth, read active/idle, write active/idle)
xrootd
- RAL enabled fireflies, but there was an issue with configuration which was found and fixed in collab. with xrootd developers
- For fallback mechanism to work we need to have both directory mapping and activity mapping in the config
EOS (CERN)
- Requested to change the configuration, so that we start tracking flows not coming from FTS/Rucio (fallback mechanism based on directory access)
- EOS team is looking into it, the change adds Scitags API URL, which becomes an operational dependency
flowd-go
- flowd-go evaluation/review (A: Marian, Tristan)
- Packaging in koji in progress (TBD)
