Unified Telemetry status report August 7, 2015

Overall Project Health

Last week: Yellow

This week: Yellow - The primary risk is now the executive report. We're still debugging the discrepancies between the v4 and the v2 versions. We will not turn off v2 data if we don't have confidence in the executive report.

Exec Summary

  • Data quality, validation
    • Team is focusing on executive dashboard roll ups in validation effort
    • added client probes to beta population to narrow down missing pings question and a few other issues
  • Added a Windows drill down for executive report data
  • Starting work on executive dashboard with combined v2 + v4 data
  • Healthreport content is up and work to use the new API is underway (no longer a big risk)
  • Proposal: if we don't feel confident turning off v2 data for Fx41, collect v4 data for 5% of the population
