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

Transaction

A transaction is a logical unit of work in a software application, such as HTTP requests, SQL queries, background processes, message queue activity, etc. The Transaction event includes information about the app, database calls, the duration of the transaction, and any errors that may occur.
