Event Telemetry

The Telemetry wiki page has more information about using Telemetry -- this page describes the Event Telemetry project.

Overview

There is a common need across teams (fx-team, mobile, test-pilot, heartbeat, …) to have a mechanism for recording, storing, sending & analysing application usage in an event-oriented format. The Data Platform team wants to support this with a common API and mechanisms for dealing with the collected data, without owning the individual measurements. The solution here is to provide common client code, a standard data format, so we can come up with common processes and tooling for data pipeline & analysis work. Historically we already send a form of UITelemetry data, but the current format is too complicated to work with and to maintain.

Dates

• ...: Event data explorable in re:dash (from pre-release channels)
• Fx52 (~2017-03-07): Event data collection implemented in Firefox Telemetry

Goals for Event Telemetry

• Enable exploratory usage behavior analysis
• Enable event data collection from Firefox and addons

Documentation

• Event Telemetry draft
• In-tree docs (to be written)

Analysis and Reporting

• Raw data using a spark cluster (ATMO): https://analysis.telemetry.mozilla.org/
• re:dash event data tables (STMO): https://sql.telemetry.mozilla.org/
