Preferences and Defines ======================= Telemetry behaviour is controlled through the mozconfig defines and preferences listed here. mozconfig Defines ----------------- ``MOZ_TELEMETRY_REPORTING`` When Defined (which it is for official builds): * If ``RELEASE_OR_BETA`` is not defined, defines ``MOZ_TELEMETRY_ON_BY_DEFAULT`` When Not Defined: * If ``datareporting.healthreport.uploadEnabled`` is locked, we print a message in the Privacy settings that you cannot turn on data submission and disabled the checkbox so you don't try. * Android: hides the data submission UI to prevent users from thinking they can turn it on * Disables Telemetry from being sent (due to ``Telemetry::IsOfficialTelemetry``) ``MOZ_TELEMETRY_ON_BY_DEFAULT`` When Defined: * Android: enables ``toolkit.telemetry.enabled`` ``MOZ_SERVICES_HEALTHREPORT`` When Defined (which it is on most platforms): * Sets ``datareporting.healthreport.{infoURL|uploadEnabled}`` in ``modules/libpref/init/all.js``. ``MOZ_DATA_REPORTING`` When Defined (which it is when ``MOZ_TELEMETRY_REPORTING``, ``MOZ_SERVICES_HEALTHREPORT``, or ``MOZ_CRASHREPORTER`` is defined (so, on most platforms, but not typically on developer builds)): * Enables ``app.shield.optoutstudies.enabled`` When Not Defined: * Disables ``app.shield.optoutstudies.enabled`` * Removes parts of the Data Collection Preferences UI in ``privacy.xhtml`` ``MOZILLA_OFFICIAL`` When Not Defined (defined on our own external builds and builds from several Linux distros, but not typically on defeloper builds): * Disables Telemetry from being sent (due to ``Telemetry::IsOfficialTelemetry``) ``MOZ_UPDATE_CHANNEL`` When not ``release`` or ``beta``: * If ``MOZ_TELEMETRY_REPORTING`` is also defined, defines ``MOZ_TELEMETRY_ON_BY_DEFAULT`` When ``beta``: * If ``toolkit.telemetry.enabled`` is otherwise unset at startup, ``toolkit.telemetry.enabled`` is defaulted to ``true`` (this is irrespective of ``MOZ_TELEMETRY_REPORTING``) When ``nightly`` or ``aurora`` or ``beta`` or ``default``: * Desktop: Locks ``toolkit.telemetry.enabled`` to ``true``. All other values for ``MOZ_UPDATE_CHANNEL`` on Desktop locks ``toolkit.telemetry.enabled`` to ``false``. * Desktop: Defaults ``Telemetry::CanRecordExtended`` (and, thus ``Telemetry::CanRecordReleaseData``) to ``true``. All other values of ``MOZ_UPDATE_CHANNEL`` on Desktop defaults these to ``false``. ``DEBUG`` When Defined: * Disables Telemetry from being sent (due to ``Telemetry::IsOfficialTelemetry``) **In Short:** For builds downloaded from mozilla.com ``MOZ_TELEMETRY_REPORTING`` is defined, ``MOZ_TELEMETRY_ON_BY_DEFAULT`` is on if you downloaded Nightly or Developer Edition, ``MOZ_SERVICES_HEALTHREPORT`` is defined, ``MOZ_DATA_REPORTING`` is defined, ``MOZILLA_OFFICIAL`` is defined, ``MOZ_UPDATE_CHANNEL`` is set to the channel you downloaded, and ``DEBUG`` is false. This means Telemetry is, by default, collecting some amount of information and is sending it to Mozilla. For builds you make yourself with a blank mozconfig, ``MOZ_UPDATE_CHANNEL`` is set to ``default`` and everything else is undefined. This means Telemetry is, by default, collecting an extended amount of information but isn't sending it anywhere. Preferences ----------- ``toolkit.telemetry.unified`` This controls whether unified behavior is enabled. If true: * Telemetry is always enabled and recording *base* data. * Telemetry will send additional ``main`` pings. It defaults to ``true``, but is ``false`` on Android (Fennec) builds. ``toolkit.telemetry.enabled`` If ``unified`` is off, this controls whether the Telemetry module is enabled. It can be set or unset via the `Preferences` dialog in Firefox for Android (Fennec). If ``unified`` is on, this is locked to ``true`` if ``MOZ_UPDATE_CHANNEL`` is ``nightly`` or ``aurora`` or ``beta`` or ``default`` (which is the default value of ``MOZ_UPDATE_CHANNEL`` for developer builds). Otherwise it is locked to ``false``. This controls a diminishing number of things and is intended to be deprecated, and then removed. ``datareporting.healthreport.uploadEnabled`` If ``unified`` is true, this controls whether we send Telemetry data. If ``unified`` is false, we don't use this value. ``toolkit.telemetry.archive.enabled`` Allow pings to be archived locally. This can only be enabled if ``unified`` is on. ``toolkit.telemetry.server`` The server Telemetry pings are sent to. Change requires restart. ``toolkit.telemetry.log.level`` This sets the Telemetry logging verbosity per ``Log.sys.mjs``. The available levels, in descending order of verbosity, are ``Trace``, ``Debug``, ``Config``, ``Info``, ``Warn``, ``Error`` and ``Fatal`` with the default being ``Warn``. By default logging goes only the console service. ``toolkit.telemetry.log.dump`` Sets whether to dump Telemetry log messages to ``stdout`` too. ``toolkit.telemetry.shutdownPingSender.enabled`` Allow the ``shutdown`` ping to be sent when the browser shuts down, from the second browsing session on, instead of the next restart, using the :doc:`ping sender `. ``toolkit.telemetry.shutdownPingSender.enabledFirstSession`` Allow the ``shutdown`` ping to be sent using the :doc:`ping sender ` from the first browsing session. ``toolkit.telemetry.firstShutdownPing.enabled`` Allow a duplicate of the ``main`` shutdown ping from the first browsing session to be sent as a separate ``first-shutdown`` ping. ``toolkit.telemetry.newProfilePing.enabled`` Enable the :doc:`../data/new-profile-ping` on new profiles. ``toolkit.telemetry.newProfilePing.delay`` Controls the delay after which the :doc:`../data/new-profile-ping` is sent on new profiles. ``toolkit.telemetry.updatePing.enabled`` Enable the :doc:`../data/update-ping` on browser updates. ``toolkit.telemetry.eventping.minimumFrequency`` The minimum frequency at which an :doc:`../data/event-ping` will be sent. Default is 60 (minutes). ``toolkit.telemetry.eventping.maximumFrequency`` The maximum frequency at which an :doc:`../data/event-ping` will be sent. Default is 10 (minutes). ``toolkit.telemetry.overrideUpdateChannel`` Override the ``channel`` value that is reported via Telemetry. This is useful for distinguishing different types of builds that otherwise still report as the same update channel. ``toolkit.telemetry.ipcBatchTimeout`` How long, in milliseconds, we batch accumulations from child processes before sending them to the parent process. Default is 2000 (milliseconds). ``toolkit.telemetry.pioneerId`` If a user has opted into the Pioneer program, this will contain their Pioneer ID. ``toolkit.telemetry.prioping.enabled`` Whether the :doc:`../data/prio-ping` is enabled. Defaults to true. Change requires restart. ``toolkit.telemetry.prioping.dataLimit`` The number of encoded prio payloads which triggers an immediate :doc:`../data/prio-ping` with reason "max". Default is 10 payloads. Data-choices notification ------------------------- ``toolkit.telemetry.reportingpolicy.firstRun`` This preference is not present until the first run. After, its value is set to false. This is used to show the infobar with a more aggressive timeout if it wasn't shown yet. ``datareporting.policy.firstRunURL`` If set, a browser tab will be opened on first run instead of the infobar. ``datareporting.policy.dataSubmissionEnabled`` This is the data submission master kill switch. If disabled, no policy is shown or upload takes place, ever. ``datareporting.policy.dataSubmissionPolicyNotifiedTime`` Records the date user was shown the policy. This preference is also used on Android. ``datareporting.policy.dataSubmissionPolicyAcceptedVersion`` Records the version of the policy notified to the user. This preference is also used on Android. ``datareporting.policy.dataSubmissionPolicyBypassNotification`` Used in tests, it allows to skip the notification check. ``datareporting.policy.currentPolicyVersion`` Stores the current policy version, overrides the default value defined in TelemetryReportingPolicy.sys.mjs. ``datareporting.policy.minimumPolicyVersion`` The minimum policy version that is accepted for the current policy. This can be set per channel. ``datareporting.policy.minimumPolicyVersion.channel-NAME`` This is the only channel-specific version that we currently use for the minimum policy version. GeckoView --------- ``toolkit.telemetry.geckoview.streaming`` Whether the GeckoView mode we're running in is the variety that uses the :doc:`GeckoView Streaming Telemetry API <../internals/geckoview-streaming>` or not. Defaults to false. ``toolkit.telemetry.geckoview.batchDurationMS`` The duration in milliseconds over which :doc:`GeckoView Streaming Telemetry <../internals/geckoview-streaming>` will batch accumulations before passing it on to its delegate. Defaults to 5000. ``toolkit.telemetry.geckoview.maxBatchStalenessMS`` The maximum time (in milliseconds) between flushes of the :doc:`GeckoView Streaming Telemetry <../internals/geckoview-streaming>` batch to its delegate. Defaults to 60000. Testing ------- The following prefs are for testing purpose only. ``toolkit.telemetry.initDelay`` Delay before initializing telemetry (seconds). ``toolkit.telemetry.minSubsessionLength`` Minimum length of a telemetry subsession and throttling time for common environment changes (seconds). ``toolkit.telemetry.collectInterval`` Minimum interval between data collection (seconds). ``toolkit.telemetry.scheduler.tickInterval`` Interval between scheduler ticks (seconds). ``toolkit.telemetry.scheduler.idleTickInterval`` Interval between scheduler ticks when the user is idle (seconds). ``toolkit.telemetry.idleTimeout`` Timeout until we decide whether a user is idle or not (seconds). ``toolkit.telemetry.modulesPing.interval`` Interval between "modules" ping transmissions. ``toolkit.telemetry.send.overrideOfficialCheck`` If true, allows sending pings on unofficial builds. Requires a restart. ``toolkit.telemetry.testing.overridePreRelease`` If true, allows recording opt-in Telemetry on the Release channel. Requires a restart. ``toolkit.telemetry.untrustedModulesPing.frequency`` Interval, in seconds, between "untrustedModules" ping transmissions. ``toolkit.telemetry.healthping.enabled`` If false, sending health pings is disabled. Defaults to true. ``toolkit.telemetry.testing.disableFuzzingDelay`` If true, ping sending is not delayed when sending between 0am and 1am local time. ``toolkit.telemetry.testing.overrideProductsCheck`` If true, allow all probes to be recorded no matter what the current product is.
