Go Agent Troubleshooting Framework Logs in Context



  • Review the Compatibility and Requirements for setting up Logs in Context for the Go agent:
  • Ensure you have distributed tracing enabled for the Go agent.
  • Double check that you have installed and implemented Logrus as the logger for your application.
    • If you aren’t using Logrus in your application you will need to manually add our context metadata to your logs by using the Agent API.
  • Make sure you have imported the necessary packages in every file where Logrus is configured.
import (

log "github.com/sirupsen/logrus"



  • Check that you have set the Logrus formatter to New Relic’s ContextFormatter:
    • log.SetFormatter(nrlogrusplugin.ContextFormatter{})
    • After implementing this your looger should now look for newrelic.Transaction inside its context and decorate logs accordingly
    • You can read more about Logrus formatters in their github repo here:
  • Review your existing logging calls and check that they are using our contextual logger rather than the standard logger.
  • You can see examples for each of the steps above in our documentation here:
  • Once you have configured the ContextFormatter it is a good idea to examine your logs to check that they are formatted as JSON and contain the following fields:
    • “entity.name”
      • 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.
    • “trace.id"
      • Will only be present if distributed tracing is enabled and a corresponding transaction generates a log.
    • "span.id”
      • 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 span.id and trace.id 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:

    • has: span.id has:trace.id
  • Check your configuration against our examples on Github:

  • Double check that you are using your logger within a Go agent transaction. If you are not then your logs will not have linkage with APM.
