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

NrDailyUsage

Data source:

Once per day, New Relic products generate a NrDailyUsage event. Use the productLine attribute to identify and filter for the specific product's usage.

Attribute nameDefinitionData types
agentHostname
ID

ID reported by the agent to uniquely identify the host for which this usage event is reported.

This value can come from several sources in the application's environment, but commonly is the value returned by the gethostname Linux syscall. In Docker environments, this attribute can take on the value (sometimes truncated) of the Docker container ID. agentHostname is one of three possible providers for the hostId value.
