Python Agent Troubleshooting Framework Logs in Context

Python ‘Logging’


  • Review the Compatibility and Requirements for setting up Logs in Context for the Python agent:
  • Ensure you have distributed tracing enabled for the Python agent.
  • Check your logging configuration:
    • Import Python’s Logging module.
    • Import New Relic’s NewRelicContextFormatter from newrelic.agent
    • Check that you’ve created a log handler in your code. There is a list of usable logging handlers in Python’s docs:
    • Check that NewRelicContextFormatter is the formatter for your log handler.
    • Check that you’ve added your new logging handler to your root logger.
    • You can see an example of the above in our docs here:

    • “”
      • Should be the application name set in APM for the service you’ve configured Logs in Context for.
    • “entity.type”
      • Should be the string “SERVICE”
    • “entity.guid”
      • The ID of the entity.
    • “"
      • Will only be present if distributed tracing is enabled and a corresponding transaction generates a log.
    • "”
      • Will only be present if distributed tracing is enabled and a corresponding span generates a log.
    • “hostname”
      • This should be the hostname gathered by the APM agent.


  • Make sure your APM language agent is installed and set up correctly.

  • Make sure that you have Distributed Tracing configured correctly for your application. If you do not you will not see a and in your log metadata.

  • If you aren’t seeing logs in the Logs UI. Ensure that you have installed and configured a New Relic plugin for a compatible log forwarder:

  • Check your Logs UI in New Relic and query using the the following:
