Code-level metrics are span attributes that the Java agent attaches to your application's spans, pinpointing the exact function and class responsible for a given span. This allows you to be more proactive about addressing performance issues as you review your code. You can view these attributes on individual spans in distributed tracing, or query them directly with NRQL.
Important
Code-level metrics are available for Java agent version 7.10.0 or higher, and enabled by default for version 7.11.0 and higher. See Java agent configuration: Config file for instructions on how to enabled or disable it.
Agent attributes
The Java agent reports and attaches the following attributes to spans produced by your application:
Name | Description | Example |
|---|---|---|
| The name of the instrumented function (Java method). | retrieveData |
| The namespace (fully qualified class name) in which | com.example.MyService |
Important
Spans created using the API method NewRelic.getAgent().getTransaction().startSegment() will not contain these attributes. To create a span that contain these attributes annotate a method with @Trace or use XML instrumentation.
