1. Experiment Support CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t DBES Author etc Dashboard Latency monitoring (Update) Alexandre Beche date

2. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 2Author etcdate Outlines Status after first proposal Current DB and collector status (credit to Daniel) Current UI status Demo Future

3. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 3Author etc Status after first proposal (20/06/2012 ) DB and DAO: –Single events table –Investigate NULL in complete timestamp VS BitMap index User Interface: –2 Pie charts : breakdown by VO and server. –2 Column charts: breakdown by VO and server + hourly bins –All filter should be applied –Details view when clicking on graphs date

4. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 4Author etc Current DB and collector status (credit to Daniel) First approach (Demo only): –A table keep track of active transfers (collector create / remove entry in the table ) –Inserting is fine whatever the number of messages –Deleting seems to be the bottleneck when number of messages is growing Second approach (merge based): –Works but history is not kept date

5. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 5Author etc Still under investigation: –Previous method can’t fit to our number of messages –Plans: Oracle stored procedure will read existing table (t_transfer_start and complete) to populate t_transfers (join) –Investigation: What is the maximum size of t_transfers to run properly? 6h, 12h, 1d, 1w ??? date Current DB and collector status (credit to Daniel)

6. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 6Author etc Current UI status All requirements have been reached (Except when clicking in “other” on charts) Design allows to add easily more breakdown: (channel, source country, …) Investigation how to add a filter by channel: –Impossible to list all the channels (about 720) –A text box should be enough? date

7. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 7Author etc Demo date

8. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 8Author etc New toolbar: UI presentation date Possible breakdown: Vo Endpnt / server Channel Src/dest country/site Type of the chart: Stack, column (col chart) Sum (pie chart) Number of series / bins you want to display: 1-10 Size of the bins: 5 / 10 /15 / 20 / 25 / 30 minutes Hourly

9. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 9Author etc Multiple plot type: A same information can be present in multiple formats: date

10. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 10Author etc Multiple breakdown: Customizable information to display date

11. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 11Author etc Multiple bins configuration Customizable size and number of time bins: date

12. CERN IT Department CH-1211 Geneva 23 Switzerland www.cern.ch/i t ES 12Author etc Future Directly related to active transfers monitoring –Work with Daniel on the DB –Work with David on xbrowse –Code refactoring Beyond “ATM”: historical data –Investigation with Daniel on statistics for t_transfers –Plot suggested by Josep Flix for CMS: Channel occupancy Througput / Streams SRM overhead date
