2. A “Virgo quality flags monitor” web page is currently produced by QcMoni
A more general “Quality monitor” web page is going to be produced taking as input xml files produced by QcMoni, the xxxMoni and BigBrother

7. Provide possibility to amend page display at user-level
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

9. Work to date – Centralised data - 1
The DM System creates a data array from three XML files and outputs them using PHP.
05/02/2019

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>
05/02/2019

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:
05/02/2019

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. Position coordinates instead of flag order
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)
05/02/2019

16. Work planned - 2
Supplying data from xxxMoni processes
05/02/2019

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?
