UI Telemetry
|
||||
==============
|
||||
|
||||
Fennec records UI events using a telemetry framework called UITelemetry.

Sessions
|
||||
========
|
||||
|
||||
**Sessions** are essentially scopes. They are meant to provide context to
|
||||
events; this allows events to be simpler and more reusable. Sessions are
|
||||
usually bound to some component of the UI, some user action with a duration, or
|
||||
some transient state.
|
||||
|
||||
For example, a session might be begun when a user begins interacting with a
|
||||
menu, and stopped when the interaction ends. Or a session might encapsulate
|
||||
period of no network connectivity, the first five seconds after the browser
|
||||
launched, the time spent with an active download, or a guest mode session.
|
||||
|
||||
Sessions implicitly record the duration of the interaction.
|
||||
|
||||
A simple use-case for sessions is the bookmarks panel in about:home. We start a
|
||||
session when the user swipes into the panel, and stop it when they swipe away.
|
||||
This bookmarks session does two things: firstly, it gives scope to any generic
|
||||
event that may occur within the panel (*e.g.*, loading a URL). Secondly, it
|
||||
allows us to figure out how much time users are spending in the bookmarks
|
||||
panel.
|
||||
|
||||
To start a session, call ``Telemetry.startUISession(String sessionName)``.
|
||||
|
||||
``sessionName``
|
||||
The name of the session. Session names should be brief, lowercase, and should describe which UI
|
||||
component the user is interacting with. In certain cases where the UI component is dynamic, they could include an ID, essential to identifying that component. An example of this is dynamic home panels: we use session names of the format ``homepanel:<panel_id>`` to identify home panel sessions.
|
||||
|
||||
To stop a session, call ``Telemetry.stopUISession(String sessionName, String reason)``.
|
||||
|
||||
``sessionName``
|
||||
The name of the open session
|
||||
|
||||
``reason`` (Optional)
|
||||
A descriptive cause for ending the session. It should be brief, lowercase, and generic so it can be reused in different places. Examples reasons are:
|
||||
|
||||
``switched``
|
||||
The user transitioned to a UI element of equal level.
|
||||
|
||||
``exit``
|
||||
The user left for an entirely different element.
|
||||
|
||||
Experiments
|
||||
===========
|
||||
|
||||
**Experiment** is a special type of a session. Experiments denote an "experiment scope".
|
||||
Just like sessions, multiple experiments might be active at the same time. Experiments are recorded
|
||||
by tagging events with an ``experiment.1:varying_experiment_name`` session. However, on the data
|
||||
pipeline side, experiment's name is parsed and stored separately (in the ``experiments`` column).
|
||||
Original ``experiment.1`` substring of the session name is stripped away.
|
||||
|
||||
For example, the following telemetry data:
|
||||
|
||||
.. code-block:: js
|
||||
|
||||
...
|
||||
sessions: ["awesomebar.1", "experiment.1:onboarding_a"]
|
||||
...
|
||||
|
||||
Will be stored as:
|
||||
|
||||
.. code-block:: js
|
||||
|
||||
...
|
||||
experiments: ["onboarding_a"],
|
||||
sessions: ["awesomebar.1"]
|
||||
...
|
||||
|
||||
Consider a case of A/B testing different variations of Activity Stream. We might want to run two
|
||||
experimental cohorts, each of them seeing a unique variation of the functionality. Depending on which
|
||||
cohort the user is in, their events while interacting with the experiments will be tagged accordingly
|
||||
with a current experiment name, while also retaining session information.
|
||||
On the analytics side it's then possible to compare performance of various metrics between cohorts.
|
||||
|
||||
Events
|
||||
======
|
||||
|
||||
Events capture key occurrences. They should be brief and simple, and should not contain sensitive or excess information. Context for events should come from the session (scope). An event can be created with four fields (via ``Telemetry.sendUIEvent``): ``action``, ``method``, ``extras``, and ``timestamp``.
|
||||
|
||||
``action``
|
||||
The name of the event. Should be brief and lowercase. If needed, you can make use of namespacing with a '``.``' separator. Example event names: ``panel.switch``, ``panel.enable``, ``panel.disable``, ``panel.install``.
|
||||
|
||||
``method`` (Optional)
|
||||
Used for user actions that can be performed in many ways. This field specifies the method by which the action was performed. For example, users can add an item to their reading list either by long-tapping the reader icon in the address bar, or from within reader mode. We would use the same event name for both user actions but specify two methods: ``addressbar`` and ``readermode``.
|
||||
|
||||
``extras`` (Optional)
|
||||
For extra information that may be useful in understanding the event (such as a short string, a json blob, etc).
|
||||
|
||||
``timestamp`` (Optional)
|
||||
The time at which the event occurred. If not specified, this field defaults to the current value of the realtime clock.
|
||||
|
||||
Versioning
|
||||
==========
|
||||
|
||||
As a we improve on our Telemetry methods, it is foreseeable that our probes will change over time. Different versions of a probe could carry different data or have different interpretations on the server-side. To make it easier for the server to handle these changes, you should add version numbers to your event and session names. An example of a versioned session is ``homepanel.1``; this is version 1 of the ``homepanel`` session. This approach should also be applied to event names, an example being: ``panel.enable.1`` and ``panel.enable.2``.
|
||||
|
||||
|
||||
Clock
|
||||
=====
|
||||
|
||||
Times are relative to either elapsed realtime (an arbitrary monotonically increasing clock that continues to tick when the device is asleep), or elapsed uptime (which doesn't tick when the device is in deep sleep). We default to elapsed realtime.
|
||||
|
||||
See the documentation in `the source <http://dxr.mozilla.org/mozilla-central/source/mobile/android/base/Telemetry.java>`_ for more details.
