2. BNL DashBoard https://webdocs.racf.bnl.gov/Facility/Monit or/dashboard.html

3. Multi-Level Monitoring ATLAS DDM Performance monitoring, (bandwidth, error rate, total volume) Each layer needs to be monitoring Given BNL and one/several Tier 2 site, a performance plot should be generated for a given period. Network, SRM/dCache/XROOTD, FTS, and USATLAS DDM

4. Site Based Network Traffic Monitoring Network: SLAC group is helping us to analyze all network flow record and group them based on source, and destination. All data transfer history can be searched. Working on improving algorithm efficiency and stability: depend on web browser. To be add into dashboard http://iepmbw.bnl.org/netflow/index.html

5. BNL / Tier 2 Production Traffic Monitored by NetFlow

6. FTS monitoring FTS data records are in a single database. A dynamic web server to wrap this database. A typical query: given site A (A1, A2, A3..) and site B (or B1, B2, …) in USATLAS, generates plots between Time t_1 and t_2. Will use a summer intern to do the job.

7. January BNL / Tier 2 Transfer Stability Exercise

8. ATLAS DDM monitoring plots Data subscription and fetch results will send to ATLAS DDM dashboard via call-back. Need to backup ATLAS DDM metrics into an archive database. Day-to-Day operation collected in AK in monitoring A similar query script can generate performance results.
