Cuando la funcionalidad está habilitada, estos atributos se agregarán a los registros de log con un prefijo context.. Para obtener detalles sobre cómo habilitar esta función, consulte la documentación de context_data.

• Aumento del límite de eventos personalizados 1036

  Esta versión aumenta el límite predeterminado de eventos personalizados de 10 000 eventos por minuto a 30 000 eventos por minuto. En el caso de que se estuvieran limitando los eventos personalizados, este cambio permitirá enviar más eventos personalizados a New Relic. También hay un nuevo límite máximo configurable de 100 000 eventos por minuto. Para cambiar los límites, consulte la documentación de max_samples_stored. Para obtener más información sobre el cambio y cómo determinar si se están descartando eventos personalizados, consulte nuestra publicación en el Explorers Hub.

• Métricas a nivel de código activadas por defecto 1037

  La funcionalidad de métricas a nivel de código introducida con el agente 7.10 ahora está habilitada de forma predeterminada. Esta función causará un aumento en el consumo de datos. La cantidad depende de la aplicación. Para desactivar las métricas a nivel de código, consulta las instrucciones en nuestra documentación de métricas a nivel de código.

Declaración de apoyo

New Relic recomienda actualizar el agente regularmente para asegurarse de obtener las últimas funciones y beneficios de rendimiento. Además, las versiones anteriores dejarán de tener soporte cuando lleguen al fin de su vida útil.

Actualizar a la última versión

Para identificar qué versión del agente de Java estás usando actualmente, ejecuta java -jar newrelic.jar -v. Su versión de agente de Java se imprimirá en su consola.

Luego, para actualizar a la última versión del agente de Java:

1. Haga una copia de seguridad de todo el directorio raíz del agente de Java en otra ubicación. Cambie el nombre de ese directorio a NewRelic_Agent#.#.#, donde #.#.# es el número de versión del agente.
2. Descarga el agente.
3. Descomprima el archivo de descarga del nuevo agente y luego copie newrelic-api.jar y newrelic.jar en el directorio raíz del agente de Java original.
4. Compare su newrelic.yml antiguo con el newrelic.yml recién descargado del zip y actualice el archivo si es necesario.
5. Reinicie su despachador de Java.

Si tiene problemas después de la actualización del agente de Java, restaure desde el directorio del agente New Relic respaldado.

Actualizar diferencias de configuración del agente

Agregamos nuevas configuraciones a newrelic.yml a medida que lanzamos nuevas versiones del agente. Puede usar diff u otra utilidad de diferenciación para ver qué ha cambiado y agregar la nueva configuración a su archivo anterior. Asegúrese de no sobrescribir ninguna personalización que haya realizado en el archivo, como su clave de licencia, el nombre de la aplicación o los cambios en la configuración predeterminada.

Por ejemplo, si diff los archivos newrelic.yml predeterminados para las versiones 7.10.0 y 7.11.0 del agente de Java , los resultados impresos en la consola serán como:

➜ diff newrelic_7.10.0.yml newrelic_7.11.0.yml
...
107a108,119
>       # Whether the log events should include context from loggers with support for that.
>       context_data:
>
>         # When true, application logs will contain context data.
>         enabled: false
>
>         # A comma separated list of attribute keys whose values should be sent to New Relic.
>         #include:
>
>         # A comma separated list of attribute keys whose values should not be sent to New Relic.
>         #exclude:
>
125a138
>
128c141
<     enabled: false
---
>     enabled: true
...

En este ejemplo, estas líneas se agregaron al newrelic.yml predeterminado en la versión 7.11.0 del agente Java. Si actualiza a la versión 7.11.0 o superior, debe agregar estas nuevas líneas a su newrelic.yml original.

New features and improvements

Added the following Jakarta EE 9/9.1 compatible instrumentation:

• Jetty 11
• Tomcat 10
• Enterprise Java Beans 4.0
• Jakarta RS/WS
• Jersey 3+
• Jersey Client 3
• JSP 3
• Servlet 5 & 6
• Jakarata.xml
• JMS 3
• Glassfish 6.0
• Open Liberty 21.0.0.12+

Code level metrics

For traced methods in automatic instrumentation or from @Trace annotations, the agent is now capable of reporting metrics with method-level granularity. When the new functionality is enabled, the agent will associate source-code-related metadata with some metrics. Then, when the corresponding Java class file that defines the methods is loaded up in a New Relic CodeStream-powered IDE, the four golden signals for each method will be presented to the developer directly.

Agent log forwarding now adds the following attributes to log events for the log4j2 and logback1.2 frameworks:

• thread.name
• thread.id
• logger.name
• logger.fqcn
• error.class
• error.stack
• error.message

Fixes

Fixed an issue with distributed tracing headers not being added on external requests made with the HttpUrlConnection client

Support statement

New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach end-of-life.

Full changelog: https://github.com/newrelic/newrelic-java-agent/compare/v7.9.0...v7.10.0

Update to latest version

To identify which version of the Java agent you're currently using, run java -jar newrelic.jar -v. Your Java agent version will be printed to your console.

Then, to update to the latest Java agent version:

1. Back up the entire Java agent root directory to another location. Rename that directory to NewRelic_Agent#.#.#, where #.#.# is the agent version number.
2. Download the agent.
3. Unzip the new agent download file, then copy newrelic-api.jar and newrelic.jar into the original Java agent root directory.
4. Compare your old newrelic.yml with the newly downloaded newrelic.yml from the zip, and update the file if needed.
5. Restart your Java dispatcher.

If you experience issues after the Java agent update, restore from the backed-up New Relic agent directory.

Update agent config differences

We add new settings to newrelic.yml as we release new versions of the agent. You can use diff or another diffing utility to see what's changed, and add the new config settings to your old file. Make sure not to overwrite any customizations you've made to the file, such as your license key, app name, or changes to default settings.

For example, if you diff the default newrelic.yml files for Java agent versions 7.7.0 and 7.8.0, the results printed to the console will be:

➜ diff newrelic_7.7.0.yml newrelic_7.8.0.yml
98c98
<     #forwarding:
---
>     forwarding:
100,101c100,101
<       # When true, application logs will be forwarded to New Relic. The default is false.
<       #enabled: false
---
>       # When true, application logs will be forwarded to New Relic. The default is true.
>       enabled: true

In this example, these lines were added to the default newrelic.yml in Java agent version 7.8.0. If you are moving to 7.8.0 or higher, you should add these new lines to your original newrelic.yml.

New features and improvements

• Where applicable, existing instrumentation has been tested and verified as compatible with Jakarta EE 8. 900
• Add new instrumentation to support Jetty 10. 936
• Update to jfr-daemon 1.9.0 to address CVE-2020-29582 and improve CPU overhead. 937
• Add support to pass a boolean environment variable NEWRELIC_DEBUG where setting it to true activates the debug configuration. 890
• Improved performance by internally replacing regex replace with iterative char replace (thanks to @zowens for this contribution) 933

Fixes

• Update the httpurlconnection instrumentation to use newer distributed tracing APIs so that spans are correctly marked as external calls in distributed traces and contain the expected http.* attributes. 885
• Illegal Access Exception is no longer thrown from apps using NR agent with scala 2.12 and Java 11. 876

Support statement
