• SSB:
    • Running in a dedicated server
    • All the latest changes in collectors
    • Google analytics since 10 days
      • Plan to move to piwik
      • On Friday 21st, from 14:00 to 15:00, SSB was inaccessible from outside CERN
    • On 3rd November, presentation on latest changes and plans of SSB
  • SAM:
    • Latest results take more than a minute to load. Still under investigation by DBA and dashboard team. Execution plan has changed, and it is not understood.


  • SSB updates:
    • Latest web interface deployed in http://dashb-ssb-test.cern.ch/
      • With urls updated in the expanded table
      • Dedicated server (fixes temporary problem changing data)
      • If there are no problems with this interface, we'll swap the aliases
    • This week we will remove the old Maintenance column.
    • Maintenance and BDII. At the moment, if site disappears from BDII, after 48 hours we don't take it into account for the downtime. Shall we increase this to 1 month? Bigger time will also affect entries that have to be deleted


  • SSB updates:
    • Presentation made for the new column TopologyMaintenances which uses cached BDII topology, new column is deployed on development machine for testing


  • SSB updates:
    • The update mentioned two weeks ago already deployed (overlaps and frequency/validity for each column)
    • Changed the Maintenance information for the default view (same information used by the google calendar)
    • Still to deploy:
      • Topology based on BDII, with cache for sites and services (this week)
      • New color definition and speed up of plots (mid August)
  • Critical-service.
    • The machine hosting this service crashed on 16th at 23 pm. The machine was rebooted on the 18th, and we have asked for a replacement


  • SSB updates:
    • Topology from BDII (thanks to Pepe)
    • New fellow (Ivan) in the group
    • New version of SSB ready to be deployed
      • Fixes overlaps in history (in production already for ATLAS)
      • Split between frequency and validity
  • Migration of the WMAgent collector from SLC4 to SLC5 (Mattia)



  • SSB updates:
    • Fixed lenses for 'under investigation'
    • Fixed BDII history (and 'history in general')
    • Getting the topology described in SiteDB
  • Still in the pipeline:


  • SSB updates:
  • New version of SSB will be deployed in development (only GUI changes, like warnings are presented in different way, detecting 'Flash blockers', or default number of rows')


  • SSB updates:
    • Deploying new SSB interface in production
    • Automatic usage of 'Under Investigation' (magnifying lenses)
    • Topology information combined with SiteDB
    • Maintenance information
  • SAM:


  • SSB updates:
  • On 7Th March, with WMAgent_0_7_X release the WMAgent should correctly report information to the Dashboard (job performance numbers will be included later on).
    • Till now no useful information is reported to the dashboard integration server . (with not useful I mean that all the parameters are reported as 'NotAvailable' value)


  • SSB updates:
    • New version of the UI will be deployed for ATLAS and LHCb. The CMS development will be done next week (1st week of March, and moving to production 2 weeks later unless anyone complains). This version contains
      • Nicer looking table for 'Expanded values'
      • Filtering, paging, sorting by any columns
      • Faster query
    • Collectors. Updated last week. Now we can insert ~200 entries per second (during the Christmas break, it took almost 30 min per entry!)


  • SSB updates:
    • Downtime collector improved with the changes required by Pepe (removing downtimes if they are removed from GOCDB/OSG, and checking if the type of the downntime has changed). These changes will be put in production these week
    • SSB collectors modified. Instead of 15 independent collectors writing to the DB, they will write to the local file system, and there will be only one inserting things in the database. This has been tested in integration for over a week, and now it will be deployed in production
