AS desktop (and soon iOS) are using the tiles pipeline for telemetry. On Android we already have a telemetry system and we need to figure out whether this is suitable for the needs of Activity Stream or whether we need to implement the same solution desktop and iOS uses. Data events: * https://github.com/mozilla/activity-stream/blob/master/data_events.md iOS client: * https://github.com/mozilla-mobile/firefox-ios/pull/2151/files * https://github.com/mozilla-mobile/onyx_ios/tree/master/OnyxClient

We want to try using our existing telemetry system. For that I'll add some of the probes [1] to our prototype and then we will look at the data in re:dash and see whether we can build the reports we are interested in. [1] https://github.com/mozilla/activity-stream/blob/master/data_events.md

We have basic telemetry (some bugs are still open) and bug 1319245 is tracking the work for richer telemetry data.
