Kinesthetics eXtreme - KX

This article explores the methods and technologies involved in enhancing event processing and recognition through the use of smart events. It discusses the tools and frameworks used for converting raw events into smart events, as well as the role of event distillers, gauges, and worklets in the overall process. The article also touches on the topics of event stream notations, XML schemas, and reconfiguration in event processing systems.

  2. Scenario: Everything running smoothly

  3. Component upgrade (or environment change, or …)

  4. Oops

  5. Let’s probe into this raw events

  6. How is this done? • Active Interfaces - callback model • AIDE (Active Interface Development Environment)– auto-instrument code, incremental instrumentation updates/overlays architectural spec • Looking at ADLs, wrappers, interceptors

  7. Package things up raw events Smart Events

  8. How is this done? • Event Packager – converts raw events to smart events via component-specific plugins (unless probes already convert) • FleXML (Flexible XML) – enables smart events to “program” recognizers and gauges, supports dynamic introduction and composition of vocabularies and processors for event posets (prefixes), by bending some XML rules

  9. Check things out raw events Smart Events

  10. How is this done? • GC-4 (Groupspace Controller, to the four corners of the earth = version 4.x) – XML-based distributed event bus and service broker, mountable on other Internet event buses • Worklets - mobile workflow agents install/update event patterns of interest, carry other mobile code payloads, perform other small tasks throughout KX • Looking at complementary event bus and mobile code technologies

  11. Hmm… this doesn’t look right raw events Smart Events Smart Events

  12. How is this done? • Event Distiller – plugs in filters, complex event, state machine recognizers via FleXML • FleXML Meta-Parser – validates against schema, invokes processors, consults Oracle for “unknown” tags, “invalid” stream prefixes • FleXML Oracle – install new event vocabularies, recognizers, processors here • Looking at event stream notations, complex event recognizers, other pattern recognition • Looking at XML Schemas, XSLT, XPath

  13. Get the word out raw events Smart Events Smart Events

  14. How is this done? • Event Notifier – subscribes to (meta-) smart events from distillers, plugs in gauges via FleXML and worklets • Workgroup Cache – caches FleXML schemas/processors, worklets, etc. throughout KX, “group”-based prefetch/push rules supports spectrum of lazy to eager deployment as well as semantics-based information sharing

  15. Gauging what’s up raw events Smart Events Smart Events

  16. How is this done? • FleXML processors - render smart events into visible gauges, reformat smart events for external analysis tools • TRIKX (TRansitional Interface for KX) – portal organizes user or role-specific portlets for gauge presentation to human and/or automated decision agents, integrates GUI for FleXML and worklet development toolkits • Looking at “corporate portals”, fisheye views, 3D immersion->2.5D flyover, XML browsers

  17. Send out the gaugents raw events Smart Events Smart Events

  18. How is this done? • Gaugents – specialized worklets oriented to reconfiguration, require Worklet Virtual Machine (WVM) adaptor for each target component/connector • Worklet junctions - encapsulate mobile code (currently Java) for each stop along re-computable itinerary • Looking at run-time Java bytecode editing/modification/reinstantiation

  19. Reconfigure raw events Smart Events Smart Events

  20. How is this done? • Process-aware systems might coordinate reconfiguration (and KX monitoring), produce/consume worklets • Looking at decentralized process modeling, enactment, coordination • Many other approaches…

  21. Yes! !

  22. AIDE 1.0 (for Java) http://www.cs.wpi.edu/~heineman/dasada/ GC-2.5 (GC-4 close) Worklets 2.x (moving target) FleXML0.9 close http://www.psl.cs.columbia.edu/software/download/ !DEMO! XUES 0.5 (XML-based Universal Event Service = Event Packager, Event Distiller, Event Notifier) by December Make up a Quad Chart Ongoing collaborations wrt probe model, useful gauges, infrastructure architecture, event representation and recognition, decentralized process technologies, demo application What’s available NOW? What’s NEXT?
