Telemetry

Telemetry is a feature that allows data collection. This is being used to collect performance metrics and other information about how Firefox performs in the wild.

Client-side, this consists of:

• data collection in Histograms, Scalars and other data structures
• assembling Telemetry pings with the general information and the data payload
• sending them to the server and local ping retention

Note: the data collection policy documents the process and requirements that are applied here.
