  1. WP4 - Monitoring Progress report sylvain.chapeland@cern.ch WP4 Workshop - CERN

  2. Work plan 3Q02 – 1Q03 • Repository server • TCP transport • C-Implementation of the repository API • Alarm display • Packaging, documentation and unit testing for release 2 • Integration and deployment on release 2 Testbed • Dynamic proxy logic in TCP transport • Perl implementation of the repository API • Java implementation of the repository API • Extended EDG sensor set • ORACLE interface • Database survey • Interface open source Database • Investigation on metric schemas • Revisit the metric configuration • Security • Web based report GUI WP4 Workshop - CERN

  3. Repository server • Released • Multithreaded • Uses MR API for insertion of samples • Much better performance noticed for UDP transport (packet loss) • SOAP connectivity for metric subscription WP4 Workshop - CERN

  4. TCP transport • Released • End to end reliable push transport of blobs with cache and recovery if server down • Stress tests to be completed with a large number of clients • Proxy configuration currently manual WP4 Workshop - CERN

  5. C-Implementation of the repository API • Released • Implements the flat file system • Includes subscription mechanism (SOAP) WP4 Workshop - CERN

  6. Alarm display • On going • Java implementation • SOAP connectivity causing delays WP4 Workshop - CERN

  7. Packaging, documentation and unit testing for release 2 • Completed • Integrated successfully • LCFGng object WP4 Workshop - CERN

  8. Integration and deployment on release 2 Testbed • Waiting for the testbed WP4 Workshop - CERN

  9. Dynamic proxy logic in TCP transport • Not started • Planned beginning 2003 • Logic to be defined • Need large scale deployment to test behavior WP4 Workshop - CERN

  10. Perl implementation of the repository API • On going • Requires a simplified MR API • String oriented interface • First tests successful with SWIG • Tcl prototype works fine WP4 Workshop - CERN

  11. Java implementation of the repository API • To be done WP4 Workshop - CERN

  12. Extended sensor set • On going (forever?) • Some new metrics: • spaceUsed • daemonCheck • executeScript • file.dump • file.tail (including pipe from lcfg logs) • processAccounting • snmp • Activity will go on with deployment, following demand WP4 Workshop - CERN

  13. ORACLE interface • On going • But an advanced prototype is ready • More details in following presentation WP4 Workshop - CERN

  14. Database survey • Completed • Prototyping necessary to confirm results in real-life environment WP4 Workshop - CERN

  15. Interface open source Database • Not started • … but soon • Should be faster because table structures now defined WP4 Workshop - CERN

  16. Investigation on metric schemas • A few thoughts already • Planned for next year • Deals with sample types • Complex: can have arrays, etc. WP4 Workshop - CERN

  17. Revisit the metric configuration • Not started • Schema defined already • But need some updates WP4 Workshop - CERN

  18. Security • Not started • Concerns mainly transport • Also some sensible configuration items WP4 Workshop - CERN

  19. Web based report GUI • On going • First prototype released • CGI interface for DB query available WP4 Workshop - CERN

  20. Out of plan items • Various MSA improvements • Daemon facilities • Now using EDG environment variables • Syslog redirection of logs • Multiple transports at the same time • Tutorial … to be tested next Thursday WP4 Workshop - CERN

  21. Users • MSA used extensively at CERN : CCS project • use UDP transport, with central PVSS DB/alarm • local correlation connected to SURE • 19 clusters with different configurations (CCS system) • 900 nodes (half computer center) • CCS sensors • production quality • mainly exception monitoring WP4 Workshop - CERN

  22. Users • Good feedback from Rutherford RAL • Connectivity to fault tolerance WP4 Workshop - CERN

  23. Plans after 1Q2003 • Complete previous list • Then… • Final picture has not many gaps left • Test and consolidate newer components • Deploy on larger scale WP4 Workshop - CERN

  24. Conclusion • Software package starts to be complete and usable • Architecture and software stable • No major problem foreseen • It’s going on well  WP4 Workshop - CERN
