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

Span

Span events are created when New Relic agents, or other tracing instrumentation tools, instrument operations that are part of a distributed trace. The operations that a span can represent include datastore queries, calls to other services, and method-level timing. For example, in an HTTP service, a span is created at the beginning of an HTTP request and completed when the HTTP server returns a response. Span attributes contain important information about the operation that the span represents (such as duration, host data, etc.), including trace state details (such as traceId, guid) that allow New Relic to connect spans together in a trace.
