  1. Detector Monitoring Centralised Displaying D.Verkindt & G.Hemming

  2. A “Virgo quality flags monitor” web page is currently produced by QcMoni A more general “Quality monitor” web page is going to be producedtaking as input xml files produced by QcMoni, the xxxMoni and BigBrother (thanks to G. Hemming, V. Dattilo, R.Spagnoli, F. Carbognani, O.Roques, D. Verkindt)

  7. Web page objectives • Incorporate data from QcMoni, Big Brother, Error Logger and IMMS into central display • Provide possibility to amend page display at user-level • Introduce fail-safes in case of problems • Manage alarm flags

  8. Hardware and software • Machine - SLVTF • Web Server - Apache 2.0.52 • Scripting Language - PHP 5.1.2 • Data - XML

  9. Work to date – Centralised data - 1 • The DM System creates a data array from three XML files and outputs them using PHP.

  10. Work to date – Centralised data - 2 • Two Xml files are provided: • One by QcMoni • One by Big Brother • 471 sub-flags in total – 127 from QcMoni and 344 from Big Brother. • Example flag structure: <qcsubflag> <flag_name></flag_name> <flag_section></flag_section> <flag_value></flag_value> <flag_status></flag_status> </qcsubflag>

  11. Work to date – Centralised data - 3 • All flags in a section array are checked for their status. The overall section flag is then set to the colour of the most critical flag (sub-flags also use the same criteria). • Order of significance: • Red (Error) • Dark Grey (Channel corrupted) • Grey (Channel not present) • Yellow (warning) • Green (No problem)

  12. Work to date – Amending page display • The third file is a configuration file, updated by administrators (V.Dattilo & R.Spagnoli). It provides the possibility to update how the page is displayed in the following ways: • Table row height • Number of columns used in each section table • The recovery procedure URL used in case of non-green sub-flag • The order in which a subflag appears on screen • Decide in which section to display the sub-flag

  13. Work to date – Fail-safes - 1 • Default - Javascript page refresh every 5s • File missing? Display message and re-attempt refresh every 5s:

  14. Work to date – Fail-safes - 2 • Data in arrays? Set refresh to 400ms. • Unforeseen error? Refresh after 6s • QcMoni data file not updating? • Check GPS and Frame Number from last refresh. • If they are the same, increment refresh_check variable by 1. • When refresh_check variable reaches 3, display red flag across the entire width of the page, stating that the file is not updating and the amount of seconds that it has not been updating.

  15. Work planned - 1 • Position coordinates instead of flag order • Monitor fail-safes & improve where required • Incorporate other flags (IMMS etc.) • Link to channels displaying error signals • Supply individual sections from xxxMoni processes. (Detailed in next slide)

  16. Work planned - 2 Supplying data from xxxMoni processes

  17. Work planned - 3 • Receiving data from QcMoni enables the overall section flag colour to be determined by the state of the flags in the related array: • By receiving data directly from the xxxMoni processes a new sub-layer is added, enabling the large number of Big Brother-provided flags to be better utilised.

  18. Potential longer-term developments • Graphical output • Topological system • Warning notification system • Other ideas?
