1 Next Generation Web Based Live Data Monitoring for W7-X Simon Dumke Wendelstein 7-X CoDaC Software Development Group Max-Planck-Institut für Plasmaphysik Greifswald, Germany 1

2 Agenda Motivation Architecture The Present The Future 2

3 Motivation Challenges at W7-X Stepping from short pulses towards Steady State Operation Live Monitoring for both scientific and organizational purposes 24/7 Monitoring of Machine Data 2004 C. Hennig, et al., A concept of online monitoring for the Wendelstein 7-X experiment, in: Proceedings of the 4th IAEA Technical Meeting on Control, Data Acquisition, and Remote Participation for Fusion Research Fusion Engineering and Design, 71 (June (1 4)) (2004), pp

4 Motivation Challenges at W7-X Implementation and Architecture from 2004 Based on UDP Multicast: shut down due to IT security needs Standalone Java App, inflexible UI layout, missing in features Stepping forward in Usability, Maintainability, Security Stepping into a big, wide world of Remote Participation Here at Greifswald: Control Room, Laboratories, Offices, Around the world: Princeton (NJ), JET, ITER, ASDEX... 4

5 Architecture Designed by W7-X: The MonA- - Architecture Scalable, Adaptable, Lightweight 5

6 Architecture Primary Components Publisher Monitoring Add-On - MonA Stream Accumulator Provider Consumer CATalog for Exchange & Relay of INformation Availability - CatERInA Data Access, Visualization & Information Client Interface Broker Subscriber 6

7 A Multi(plexer)talent Stream Accumulator Monitoring Add-On Monitoring - Add-On Monitoring - Add-On MonA Monitoring - Add-On MonA Monitoring Add-On - MonA - MonA MonA Stream Accumulator Stream Accumulator 7

8 A Multi(plexer)talent is stackable! Monitoring Add-On - MonA Also possible: Multi layer stacking Domain Specific (e.g. Extranet for Remote Participation)??? Stream Accumulator Stream Accumulator Stream Accumulator Stream Accumulator Stream Accumulator DAVInC 8

9 A modern data streaming client Distributed & diverse users around the world in their location in their platforms & tools in their needs and interests Modern UX and maximized versatility using web technologies CATalog for Exchange & Relay of INformation Availability - CatERInA Server - Client 9

10 A modern data streaming client Key Points during Development For data distribution: WebSockets vs. WebRTC Cons: TCP for streaming data, many simultaneous connections Pros: Effort for server -side integration, mature technology, integrity & order of data For data visualization: D3.js/SVG vs. WebGL Cons: Library support, rich features, nice looks Pros: Performance, performance, performance... 10

11 The Present In productive use: Has been and is used for component commissioning 24/7 live monitoring at the W7-X Control Room since beginning of last week Running CatERInA,, MonA One MultiMonA technology adapter 11

12 The Present 12

13 The Future Fully deploy the MonA- Remove MultiMonA 2nd CatERInA + stacked for Remote Participation (Extranet) Deploy/Release s as needed Monitor new things Video streams Experiment program progress Events & Conditions Expecting new requirements: OP 1.2a starts in August 13

14 Thank you for your kind attention!
