Metrics

This document enumerates the metrics collected by this project. This project may depend on other projects which also collect metrics. This means you might have to go searching through the dependency tree to get a full picture of everything collected by this project.

Pings

activation

This ping is intended to provide a measure of the activation of mobile products. It's generated when Fenix starts, right after Glean is initialized. It doesn't include the client_id, since it might be reporting an hashed version of the Google Advertising ID.

The following metrics are added to the ping:

Name Type Description Data reviews Extras Expiration
activation.activation_id uuid An alternate identifier, not correlated with the client_id, generated once and only sent with the activation ping. 1 2020-09-01
activation.identifier string A hashed and salted version of the Google Advertising ID from the device. This will never be sent in a ping that also contains the client_id. 1 2020-09-01
