Pings
activation
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.

| events.app_opened_all_startup | event | This probe has a known flaw: for COLD start up, it doesn't take into account if the process is already running when the app starts, possibly inflating results (e.g. a Service started the process 20min ago and only now is HomeActivity launching). See the cold_*_app_to_first_frame probes for a replacement. A user opened the app to the HomeActivity. The HomeActivity encompasses the home screen, browser screen, settings screen, collections and other screens in the nav_graph. This differs from the app_opened probe because it measures all startups, not just cold startup. Note: There is a short gap between the time application goes into background and the time android reports the application going into the background. Note: This metric does not record souce when app opened from task switcher: open application -> press home button -> open recent tasks -> choose fenix. In this case will report [source = unknown, type = hot, has_saved_instance_state = false]. |

| events.app_received_intent | event | The system received an Intent for the HomeActivity. An intent is received an external entity wants to the app to display content. Intents can be received when the app is closed – at which point the app will be opened – or when the app is already opened – at which point the already open app will make changes such as loading a url. This can be used loosely as a heuristic for when the user requested to open the app. The HomeActivity encompasses the home screen and browser screen but may include other screens. This differs from the app_opened probe because it measures all startups, not just cold startup. | mozilla-mobile/fenix#11940/, mozilla-mobile/fenix#13958 |

| perf.startup.app_on_create_to_megazord_init | timing_distribution | A subsection of the duration of FenixApplication.onCreate and thus the application_on_create probe from after the app_on_create_to_glean_init probe until we block for the megazord to complete set up. |

| perf.startup.cold_main_app_to_first_frame | timing_distribution | The duration from *Application's initializer to the first Android frame being drawn in a COLD MAIN start up. Notably, this duration omits the time from process start to the initializer (which includes a lengthy dex operation) and the time from the first frame to visual completeness. This probe doesn't measure Custom Tabs or other uses of ExternalAppBrowserActivity to simplify result analysis. The methodology for determining this measurement is imperfect to simplify implementation. Issues may include: - Not measuring Beta and Release channels (due to MigrationDecisionActivity interrupting the logic). - Not distinguishing between MAIN to homescreen, onboarding, session restore, others? - Not choosing to record a MAIN based on what the user would see and thus the core code path (i.e. the thing we want to measure) but rather on the initial Intent state. The hope is that these cases will not have a significant impact on the end results but, if they appear to, we can replace it with a more complex implementation. Around April 8, 2021 the implementation was refactored. Functionally, it should be the same but it's noted just in case there are bugs. |
mozilla-mobile/fenix#18632 | 2021-08-11 | 1 | |
| perf.startup.cold_unknwn_app_to_first_frame | timing_distribution | The duration from *Application's initializer to the first Android frame being drawn in a COLD start up where we can't say it was a MAIN or VIEW start up. The methodology for determining this measurement is imperfect to simplify implementation. See the cold_main_app_to_first_frame probe docs for known issues and more details. Around April 8, 2021 the implementation was refactored. Functionally, it should be the same but it's noted just in case there are bugs. |
mozilla-mobile/fenix#18632 | 2021-08-11 | 1 | |
| perf.startup.cold_view_app_to_first_frame | timing_distribution | The duration from *Application's initializer to the first Android frame being drawn in a COLD VIEW start up. The methodology for determining this measurement is imperfect to simplify implementation. Issues may include: -Including VIEW intents that aren't valid so take code paths similar to MAIN (this is speculative) See the cold_main_app_to_first_frame probe docs for other possible known issues and more details. Around April 8, 2021 the implementation was refactored. Functionally, it should be the same but it's noted just in case there are bugs. |
mozilla-mobile/fenix#18632 | 2021-08-11 | 1 | |
| perf.startup.home_activity_on_create | timing_distribution | The duration of HomeActivity.onCreate. |
mozilla-mobile/fenix#17973 | 2021-08-11 | 1 | |
| perf.startup.home_activity_on_start | timing_distribution | The duration of HomeActivity.onStart. This may encapsulate HomeFragment or BrowserFragment creation, depending on the code path, so we expect this to take varying amounts of time. As such, this probe may not be easy to interpret directly but we believe collecting it may give us more information about different patterns we might see in performance data. |

| perf.startup.startup_type | labeled_counter | Indicates how the browser was started. The label is divided into two variables. state is how cached the browser is when started. path is what code path we are expected to take. Together, they create a combined label: state_path. For brevity, the specific states are documented in the Fenix perf glossary. This implementation is intended to be simple, not comprehensive. We list the implications below. These ways of opening the app undesirably adds events to our primary buckets (non- unknown cases): - App switcher cold/warm: cold/warm_ + duplicates path from previous launch - Home screen shortcuts: *_view - An Intent is sent internally that's uses ACTION_MAIN or ACTION_VIEW could be: *_main/view (unknown if this ever happens) - A command-line launch uses ACTION_MAIN or ACTION_VIEW could be: *_main/view These ways of opening the app undesirably do not add their events to our primary buckets: - Close and reopen the app very quickly: no event is recorded. These ways of opening the app don't affect our primary buckets: - App switcher hot: hot_unknown - PWA (all states): unknown_unknown - Custom tab: unknown_view - Cold start where a service or other non-activity starts the process (not manually tested) - this seems to happen if you have the homescreen widget: unknown_* - Another activity is drawn before HomeActivity (e.g. widget voice search): unknown_* - Widget text search: *_unknown In addition to the events above, the unknown state may be chosen when we were unable to determine a cause due to implementation details or the API was used incorrectly. We may be able to record the events listed above into different buckets but we kept the implementation simple for now. N.B.: for implementation simplicity, we duplicate the logic in app that determines path so it's not perfectly accurate. In one way, we record we is intended to happen rather than what actually happened (e.g. the user may click a link so we record VIEW but the app does a MAIN by going to the homescreen because the link was invalid). |

| storage.stats.app_bytes | memory_distribution | The size of the app's APK and related files as installed: this is expected to be larger than download size. This is the output of StorageStats.getAppBytes so see that for details. This value is only available on Android 8+. A similar value may be available on the Google Play dashboard: we can use this value to see if that value is reliable enough. | mozilla-mobile/fenix#12876, mozilla-mobile/fenix#17704 | 2021-08-01 | 1, 2 | |
| storage.stats.cache_bytes | memory_distribution | The size of all cached data in the app. This is the output of StorageStats.getCacheBytes so see that for details. This value is only available on Android 8+. | mozilla-mobile/fenix#12876, mozilla-mobile/fenix#17704 | 2021-08-01 | 1, 2 | |
| storage.stats.data_dir_bytes | memory_distribution | The size of all data minus cache_bytes. This is the output of StorageStats.getDataBytes except we subtract the value of cache_bytes so the cache is not measured redundantly; see that method for details. This value is only available on Android 8+. |

startup-timeline
This ping is intended to provide an understanding of startup performance.
In addition to being captured on real devices, the ping data was prematurely optimized into this separate ping to be isolated from other metrics to be more easily captured by performance testing automation but that hasn't happened in practice. We would have removed it but implementation details don't make that possible: https://github.com/mozilla-mobile/fenix/issues/17972#issuecomment-781002987

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 |
|---|---|---|---|---|---|---|
| startup.timeline.clock_ticks_per_second_v2 | quantity | The number of clock tick time units that occur in one second on this particular device. This value is expected to be used in conjunction with the framework_primary/secondary metrics. |

| startup.timeline.framework_primary | timespan | The duration the Android framework takes to start before letting us run code in *Application.init when this device has clock_ticks_per_second_v2 equal to 100: if it's not equal to 100, then this value is captured in framework_secondary. We split this into two metrics to make it easier to analyze in GLAM. We split on 100 because when we did our initial brief analysis - https://sql.telemetry.mozilla.org/queries/75591 - the results for clocks ticks were overwhelmingly 100. The duration is calculated from appInitTimestamp - processStartTimestamp. processStartTimestamp is derived from the clock tick time unit, which is expected to be less granular than nanoseconds. Therefore, we convert and round our timestamps to clock ticks before computing the difference and convert back to nanoseconds to report. For debugging purposes, clock_ticks_per_second_v2, which may vary between devices, is also reported as a metric |

| startup.timeline.framework_secondary | timespan | The duration the Android framework takes to start before letting us run code in *Application.init when this device has clock_ticks_per_second_v2 not equal to 100. For more details on this metric, see framework_primary |

| startup.timeline.framework_start_error | boolean | An error when attempting to record framework_primary/secondary - the application init timestamp returned a negative value - which is likely indicative of a bug in the implementation. |
mozilla-mobile/fenix#9788, mozilla-mobile/fenix#15713 | 2021-08-01 | 1 | |
| startup.timeline.framework_start_read_error | boolean | An error when attempting to read stats from /proc pseudo-filesystem - privacy managers can block access to reading these files - the application will catch a file reading exception. | mozilla-mobile/fenix#10481, mozilla-mobile/fenix#15713 | 2021-08-01 | 1 |
