Code-level metrics

Code-level metrics allow developers using the New Relic CodeStream extension to see APM data displayed contextually in their IDE, alongside individual methods in the code. This allows developers to be more proactive about addressing performance issues as they write and review code.

Getting started

First, install the New Relic CodeStream extension into your supported IDE of choice and login.

Important

Code-level metrics are available for Python agent version 7.10.0.175 and higher and are enabled by default. To change this configuration, check out our documentation.

Agent attributes

The Python agent reports and attaches the following attributes to spans produced by your application:

Name

Description

Example

code.function

The name of the instrumented function

validate_credentials

code.filepath

The absolute path to the source code file in which code.function is defined

/usr/local/apps/test-app/main.py

code.lineno

The line number where code.function is defined in code.filepath

639

code.namespace

The namespace (class/ module name) in which code.function is defined

example.service.MyService

Important

Not every function in your application code will be instrumented with the above attributes. In some cases, the agent will directly wrap base framework code (ie. Django, Flask, etc.) that is invoked within your application and will not display within your IDE.
