General updates

  • Still a CY, welcome back Chase!

  • jam@, ojan@, jparent@ all gone until January. Please send updates if you ARE working.  Regroup in January.

Area updates

Flakiness:

  • 2.4% (still mostly oddballs)

  • jam@: how long were these outages?

    • ~1 day. But hard to measure.

    • jam@: There will always be bad things checked in. But we need to detect it sooner. sergey@ change goes in, 1 hour cycle time, 30 mins or so before someone notices badness, CQ keeps going …  If there are outages > say 4 hours, we really should be able to do better than this.

    • when jobs fail on trybots without patch, surface THIS to sheriff.  This is an earlier signal into issues (AI: sergey will follow up on this)

      • ojan@ says persistent without patch failures would be easy to surface, but this is less useful

  • alancutter adding flakiness data to som (no update, did not work on it last week). Will be doing this week, adding more detail into particular tryjobs

  • open bug on adding flakiness of actual builders, needs owner: http://crbug.com/436967 (AI: jparent -find someone to do this)

CQ Matches Waterfall:

  • automated metric for determining match main waterfall bot matching ng bots.  Now: 29.6%. This metric is a bit lower because only covers ng bots. Notable exceptions: android (but this is being converted now. they don’t do retry without patch yet)

  • sergiy still making progress on capacity estimates and

Monitoring:

  • Pingdom still catching outages before our users have to notify us! (today, crbug)

  • More discussions with ACQ_SRE for [internal google monitoring product ] access. On track for this week.

Tree Open:

  • no real updates.

  • sean is ramping up on som

Fast Cycles:

  • no updates
