That is, it describes Firefox Suggest telemetry recorded on the +client. It also discusses the data that Firefox sends to the Merino service. + +For information on other telemetry related to the address bar, see the general +address bar :doc:`telemetry` document. For information on all telemetry in +Firefox, see the toolkit :doc:`/toolkit/components/telemetry/index` document. + +.. toctree:: + :caption: Table of Contents + + firefox-suggest-telemetry + +Histograms +---------- + +The following histograms are recorded for Firefox Suggest. For general +information on histogram telemetry in Firefox, see the +:doc:`/toolkit/components/telemetry/collection/histograms` document. + +FX_URLBAR_MERINO_LATENCY_MS +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +This histogram records the latency in milliseconds of the Merino source for +suggestions, or in other words, the time from Firefox's request to the Merino +server to the time Firefox receives a response. It is an exponential histogram +with 50 buckets and values between 0 and 30000 (0s and 30s). + +Changelog + Firefox 93.0 + Introduced. [Bug 1727799_] + +.. _1727799: https://bugzilla.mozilla.org/show_bug.cgi?id=1727799 + +FX_URLBAR_MERINO_LATENCY_WEATHER_MS +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +This histogram records the latency in milliseconds of weather suggestions from +Merino. It is updated in addition to ``FX_URLBAR_MERINO_LATENCY_MS`` and has the +same properties. It is an exponential histogram with 50 buckets and values +between 0 and 30000 (0s and 30s). + +Changelog + Firefox 110.0 + Introduced.

It has the following categories: + +:0 "success": + The fetch completed without any error before the timeout elapsed and it + included at least one suggestion. (Before Firefox 110.0, this category meant + simply that the fetch completed without any error before the timeout elapsed + regardless of whether it included any suggestions.) +:1 "timeout": + The timeout elapsed before the fetch completed or otherwise failed. +:2 "network_error": + The fetch failed due to a network error before the timeout elapsed. e.g., the + user's network or the Merino server was down. +:3 "http_error": + The fetch completed before the timeout elapsed but the server returned an + error. +:4 "no_suggestion": + The fetch completed without any error before the timeout elapsed and it did + not include any suggestions. + +Changelog + Firefox 94.0.2 + Introduced.

It is +an exponential histogram with 50 buckets and values between 0 and 30000 (0s and +30s). + +Note that unlike Merino, fetches from remote settings happen entirely on the +client, so remote settings latencies are expected to be much smaller than Merino +latencies. + +Changelog + Firefox 94.0.2 + Introduced.

The +event's objects are the following possible values: + +:hit: + Recorded when an impression cap is hit. +:reset: + Recorded when a cap's counter is reset because its interval period has + elapsed. The implementation may batch multiple consecutive reset events for a + cap in a single telemetry event; see the ``eventCount`` discussion below. + Reset events are reported only when a cap's interval period elapses while + Firefox is running. + +The event's ``extra`` contains the following properties: + +:count: + The number of impressions during the cap's interval period. +:eventCount: + The number of impression cap events reported in the telemetry event. This is + necessary because the implementation may batch multiple consecutive "reset" + events for a cap in a single telemetry event. When that occurs, this value + will be greater than 1, ``startDate`` will be the timestamp at which the + first event's interval period started, ``eventDate`` will be the timestamp at + which the last event's interval period ended, and ``count`` will be the number + of impressions during the first event's interval period. (The implementation + guarantees that reset events are batched only when the number of impressions + for all subsequent interval periods is zero.) For "hit" events, + ``eventCount`` will always be 1. +:eventDate: + The event's timestamp, in number of milliseconds since Unix epoch. For "reset" + events, this is the timestamp at which the cap's interval period ended. If + ``eventCount`` is greater than 1, it's the timestamp at which the last + interval period ended. For "hit" events, this is the timestamp at which the + cap was hit. +:impressionDate: + The timestamp of the most recent impression, in number of milliseconds since + Unix epoch. +:intervalSeconds: + The number of seconds in the cap's interval period.

When Merino integration is enabled on the client and the user +has opted in to Firefox Suggest data collection, Firefox sends everything the +user types in the address bar to the Merino server.
