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](https://mozilla.github.io/glean/book/user/metrics/uuid.html) |An alternate identifier, not correlated with the client_id, generated once and only sent with the activation ping. |[1](https://github.com/mozilla-mobile/fenix/pull/1707#issuecomment-486972209)||2019-10-01 |
| activation.identifier |[string](https://mozilla.github.io/glean/book/user/metrics/string.html) |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](https://github.com/mozilla-mobile/fenix/pull/1707#issuecomment-486972209)||2019-10-01 |
## baseline

If the search engine is bundled with Fenix `search-engine-name` will be the name of the search engine. If it's a custom search engine (defined: https://github.com/mozilla-mobile/fenix/issues/1607) the value will be `custom`. `source` will either be `action` or `suggestion` |[1](https://github.com/mozilla-mobile/fenix/pull/1677), [2](https://github.com/mozilla-mobile/fenix/pull/5216)||2020-03-01 |

This is a built-in ping that is assembled out of the box by the Glean SDK.
See the Glean SDK documentation for the [`metrics` ping](https://mozilla.github.io/glean/book/user/pings/metrics.html).
The following metrics are added to the ping:
| Name | Type | Description | Data reviews | Extras | Expiration |
| --- | --- | --- | --- | --- | --- |
| experiments.metrics.active_experiment |[string](https://mozilla.github.io/glean/book/user/metrics/string.html) |Records the branch name of the active experiment, if the client is enrolled in the `fenix-test-2019-08-05` experiment. This is intended to validate that the service-experiments library properly matches clients to experiments and can take action based on a multi-branched experiment. This is done by recording the experiment branch name in this string metric which allows the experiment to be transparent and unobtrusive to the user. |[1](https://bugzilla.mozilla.org/show_bug.cgi?id=1543986#c4)||2019-11-01 |
