New Relic data dictionary

This data dictionary defines some of our default-reported data stored in NRDB and queryable via NRQL. This includes events like Transaction, MobileRequest, and BrowserInteraction, and our Metric, Log, and Span data types. These definitions are also available from our query builder UI by mousing over applicable data type and attribute names.

This dictionary doesn't contain:

  • Data from our infrastructure integrations (for that, see docs for a specific integration)
  • Custom data
  • Detailed integration-specific attributes for Metric data

MobileApplicationExit

Data source:

A MobileApplicationExit event is generated when an app terminates, either due to a crash or other reasons such as low memory, ANRs, etc. Currently, this event is reported only for Android mobile applications. It leverages Android’s ApplicationExitInfo API to monitor and report on the different reasons for your app’s termination.

This event provides valuable insights into the circumstances surrounding the app's termination and includes attributes such as reason, description, etc. For example, to understand the different reasons for your app exit, you would look at the reason attribute. For all ANRs, the reason would be 6, for crashes it would be 4, and so on, as described in the Android documentation. For a human readable description for your app exit, try looking at the description attribute.

Attribute nameDefinitionData types
sessionDuration
seconds (s)

The length of time for which the user used the application in seconds. If the session crashes, sessionDuration is not captured (although other events and attributes are still recorded).

For sessions longer than the configured event harvest cycle, events in the Interaction and Custom event categories are sent to New Relic while the session is ongoing, and therefore do not have sessionDuration attributes, but they do have timeSinceLoad attributes. Events recorded near the end of the session may include the duration.
