APM logs in context connects your logs with all of your telemetry data for your apps, hosts, and other entities. Bringing all of this data together in a single tool helps you quickly:
- Cut through the noise of thousands of logs when troubleshooting time-critical issues, so you automatically see only the most relevant logs.
- Navigate within multiple types of telemetry data, and have the data correlate back to the original issue.
- Easily drill down into more detailed information from the same place in the UI.
- Find the log lines that you need to identify and resolve a problem.

If you are using a supported framework, you have two options to configure APM logs in context to send your app's logs and linking metadata automatically to New Relic. Supported frameworks for automatic logs in context include:
- Log4j 2 2.6 or higher
- Logback 1.1 or higher
Agent releases 7.7.0 and higher have this feature enabled in the agent configuration file by default.
Agent log forwarding will cause an increase in the consumption of data when a supported framework is detected. The amount depends on the application and amount of logs it produces. This feature can be disabled. See Disable automatic logging for more information about your options.
If you already have a log forwarding solution in place, you should disable this feature.
If you are using a different logging framework, our manual logs in context solution might be right for you.
Your logs may include sensitive information protected by HIPAA or other compliance protocols. By default we obfuscate number patterns that appear to be for items such as credit cards or Social Security numbers, but you may need to hash or mask additional information.
For more information, see our documentation about obfuscation expressions and rules. You can hash or mask your log data by using the New Relic UI or by using NerdGraph, our GraphQL API.
To make the most of your logging data:
- On the APM Summary page, click your Web transaction time chart to view logs associated with a specific point in time.
- Check your app's Errors inbox to view the logs associated with your errors.
- Use distributed tracing to see the logs associated with individual traces.
- Explore more logging data across your platform with our Logs UI.
- Set up alerts based on log output and severity.
- Query your data using our specialized UI for logs data, and create dashboards with the results.
Typically your logs will start to appear less than a minute after you enable APM logs in context. Check your app's Triage > Logs section. You will also start seeing log patterns related to the error there.
If you don't see any logs for errors or traces, there may not be any for your app. Try refreshing the UI page, or change the selected time period.
APM logs in context automatically forwards APM agent log data and is enabled by default. This can have a negative impact on your security, compliance, billing, or system performance. For more information, or if you need to adjust the default setting, follow the procedures to disable automatic logging.
Before language agents had the ability to forward and decorate logs, you could use our manual solutions to send linking metadata.
This option is still supported, but is no longer encouraged. Also, this method requires that you install a log forwarder before enabling logs in context. If you do not have a log forwarder, the New Relic UI will prompt you to use our infrastructure agent.
If you decide to use your existing log forwarding solution and later decide to update your agent to use automatic logs in context, be sure to disable your manual log forwarder. Otherwise, your app will be sending double log lines. Depending on your account, this could result in double billing. For more information, follow the procedures to disable your specific log forwarder.
If you need to use the manual process to set up logs in context for Java, follow these steps:
- Make sure you have already set up logging in New Relic. This includes configuring a supported log forwarder that collects your application logs and extends the metadata that is forwarded to New Relic.
- Install or update to the latest Java agent version. Use Java agent version 5.6.0 or higher for logs in context.
- Enable the JVM argument
-javaagent, and enable distributed tracing.
- Configure logs in context for Java to enrich your log data, using any of the following extensions as applicable. If you use Spring or Spring Boot and aren't sure which extension you need, see our Spring documentation.
