A ping sent for every Addresses engine sync. It doesn't include the client_id because it reports a hashed version of the user's Firefox Account ID.

Bugs related to this ping:
All Glean pings contain built-in metrics in the ping_info and client_info sections.
In addition to those built-in metrics, the following metrics are added to the ping:
| Name | Type | Description | Data reviews | Extras | Expiration | Data Sensitivity |
|---|---|---|---|---|---|---|
| addresses_sync.failure_reason | labeled_string | Records why the addresses sync failed: either due to an authentication error, unexpected exception, or other error. The error strings are truncated and sanitized to omit PII, like URLs and file system paths. | mozilla-mobile/android-components#10372 |
|
never | 2 |
| addresses_sync.finished_at | datetime | Records when the addresses sync finished. This includes the time to download, apply, and upload all records. | mozilla-mobile/android-components#10372 | never | 2 | |
| addresses_sync.incoming | labeled_counter | Records incoming addresses record counts. applied is the number of incoming records that were successfully stored or updated in the local database. failed_to_apply is the number of records that were ignored due to errors. reconciled is the number of merged records. |
mozilla-mobile/android-components#10372 |
|
never | 2 |
| addresses_sync.outgoing | labeled_counter | Records outgoing addresses record counts. uploaded is the number of records that were successfully sent to the server. failed_to_upload is the number of records that weren't uploaded, and will be retried on the next sync. |
mozilla-mobile/android-components#10372 |

| addresses_sync.outgoing_batches | counter | Records the number of batches needed to upload all outgoing records. The Sync server has a hard limit on the number of records (and request body bytes) on the number of records that can fit into a single batch, and large syncs may require multiple batches. | mozilla-mobile/android-components#10372 | never | 2 | |
| addresses_sync.started_at | datetime | Records when the addresses sync started. | mozilla-mobile/android-components#10372 | never | 2 | |

A summary ping, sent every time a sync is performed. During each Sync one or more data types could be synchronized, depending on which data types user configured to sync. Alongside with 'sync' ping one or more individual data type specific pings will be sent. For example, if history and bookmarks data types are configured to be synchronized, the following pings will be sent: 'sync', 'history-sync' and 'bookmarks-sync'. Alternatively, if only history is configured to be synchronized then 'sync' and 'history-sync' pings will be sent. In case of a "global failure" where none of the data type syncs could even start, e.g. device is offline, only the 'sync' ping will be sent. This ping doesn't include the client_id because it reports a hashed version of the user's Firefox Account ID.
