Lifecycle metric name
Description
Context data variable
First Launches
The number of times the app was run for the first time after it was installed or reinstalled.
a.InstallEventUpgrades
The number of times the app was run for the first time after an upgrade, or after its version number changed.
a.UpgradeEventLaunches
The number of times the app was run, including runs after crashes and installs. A launch is also counted when the app resumes from the background after the lifecycle session timeout is exceeded.
a.LaunchEventCrashes
The number of times the app crashed before it was closed. The crash is reported the next time the app is started.
a.CrashEventTotal Session Length
The total number of seconds that app sessions lasted, based on how long the app was open and in the foreground. Each launch reports the length of the previous session; this metric is the sum of those values.
a.PrevSessionLengthAction Time Total
The total number of seconds (clock time) between the start and end of a timed action, across sessions. Populated by the
trackTimedAction methods in the legacy Mobile Services SDK (4.x).a.action.time.totalAction Time In App
The number of seconds spent in the app between the start and end of a timed action, across sessions. Populated by the
trackTimedAction methods in the legacy Mobile Services SDK (4.x).a.action.time.inappLifetime Value (event)
The lifetime value of a user, such as lifetime purchases, ad views, video completes, or social shares. Populated by the
trackLifetimeValueIncrease method in the legacy Mobile Services SDK (4.x).a.ltv.amountNOTE
The Action Time Total, Action Time In App, and Lifetime Value (event) metrics are populated by methods in the legacy Mobile Services SDK (4.x), which is no longer supported. The Adobe Experience Platform Mobile SDK does not populate these metrics automatically. See Adobe Mobile Library (v4) to Experience Platform Analytics migration for alternatives to timed actions and lifetime value tracking.
