3.20.1

중요

We recommend updating to the latest agent version as soon as it’s available.

Added

  • New integration nrpgx5 v1.0.0 to instrument github.com/jackc/pgx/v5.

Changed

  • Changed the following TraceOption function to be consistent with their usage and other related identifier names. The old names remain for backward compatibility, but new code should use the new names.
    • WithIgnoredPrefix -> WithIgnoredPrefixes
    • WithPathPrefix -> WithPathPrefixes
  • Implemented better handling of Code Level Metrics reporting when the data (e.g., function names) are excessively long, so that those attributes are suppressed rather than being reported with truncated names. Specifically:
    • Attributes with values longer than 255 characters are dropped.
    • No CLM attributes at all will be attached to a trace if the code.function attribute is empty or is longer than 255 characters.
    • No CLM attributes at all will be attached to a trace if both code.namespace and code.filepath are longer than 255 characters.

Go agent v3.20.0

3.20.0

LEA estos cambios y verifique los ajustes de configuración para asegurarse de que la aplicación se comporte como desea. Esta versión cambia algunos comportamientos predeterminados en el agente de Go.

Agregado

  • Se agregó la característica de métricas de dependencia de módulos. Esto recopila la lista de módulos importados en la aplicación, para ayudar en la gestión de las dependencias de la aplicación, lo que permite una detección y respuesta a vulnerabilidades más sencilla, etc.

    • Esta característica está habilitada de forma predeterminada, pero puede deshabilitarse incluyendo explícitamente ConfigModuleDependencyMetricsEnable(false) en la aplicación, o configurando la variable de entorno equivalente o el campo Config directamente.
    • Los módulos pueden excluirse explícitamente del informe mediante la opción ConfigModuleDependencyMetricsIgnoredPrefixes.
    • Los nombres de los módulos excluidos pueden redactarse mediante la opción ConfigModuleDependencyMetricsRedactIgnoredPrefixes. Está habilitado de forma predeterminada.

  • Application Log Forwarding ahora estará HABILITADO por defecto

    • El reenvío automático de logs de aplicación ahora está habilitado de forma predeterminada. Esto significa que los frameworks de registro envueltos con una de las integraciones de logcontext-v2 enviarán automáticamente logs de aplicación enriquecidos a New Relic con esta versión del agente. Para obtener más información sobre esta característica, consulte la documentación de logs en el contexto de APM. Para opciones de configuración adicionales, consulte la documentación de logs en el contexto de Go. Para obtener información sobre cómo activar o desactivar la ingesta de logs por cuenta, consulte nuestra documentación para deshabilitar el registro automático a través de la UI o la API.
    • Si utiliza una extensión logcontext-v2, pero no desea que el agente reenvíe los logs automáticamente, configure ConfigAppLogForwardingEnabled(false) en su aplicación.
    • Se han agregado variables de entorno para todas las opciones de configuración de logging de la aplicación:
      • NEW_RELIC_APPLICATION_LOGGING_ENABLED
    • NEW_RELIC_APPLICATION_LOGGING_FORWARDING_ENABLED
    • NEW_RELIC_APPLICATION_LOGGING_FORWARDING_MAX_SAMPLES_STORED
    • NEW_RELIC_APPLICATION_LOGGING_METRICS_ENABLED
    • NEW_RELIC_APPLICATION_LOGGING_LOCAL_DECORATING_ENABLED

  • Aumento del límite de eventos personalizados

Cambió

  • Se cambiaron los siguientes nombres para que sean coherentes con su uso y otros nombres de identificadores relacionados. Los nombres antiguos se mantienen por compatibilidad con versiones anteriores, pero el código nuevo debe usar los nombres nuevos.

    • ConfigCodeLevelMetricsIgnoredPrefix -> ConfigCodeLevelMetricsIgnoredPrefixes
    • ConfigCodeLevelMetricsPathPrefix -> ConfigCodeLevelMetricsPathPrefixes
    • NEW_RELIC_CODE_LEVEL_METRICS_PATH_PREFIX -> NEW_RELIC_CODE_LEVEL_METRICS_PATH_PREFIXES
    • NEW_RELIC_CODE_LEVEL_METRICS_IGNORED_PREFIX -> NEW_RELIC_CODE_LEVEL_METRICS_IGNORED_PREFIXES

  • Al excluir la información reportada por CodeLevelMetrics mediante los campos de configuración IgnoredPrefixes o PathPrefixes (por ejemplo, al especificar ConfigCodeLevelMetricsIgnoredPrefixes o ConfigCodeLevelMetricsPathPrefixes), los nombres de los prefijos ignorados y los prefijos de ruta configurados ahora pueden ocultarse de la información de configuración del agente enviada a New Relic.

    • Esta ocultación está habilitada de forma predeterminada, pero se puede deshabilitar proporcionando un valor false a ConfigCodeLevelMetricsRedactPathPrefixes o ConfigCodeLevelMetricsRedactIgnoredPrefixes, o estableciendo los campos Config o las variables de entorno correspondientes en false.

Fijado

  • #583: se corrigió un error en zerologWriter donde los campos separados por comas en el mensaje de log confundían al analizador JSON y podían causar pánicos.

Declaración de apoyo

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

También recomendamos usar la última versión del lenguaje Go. Como mínimo, no debería usar ninguna versión de Go anterior a la que admite el propio equipo de Go.

Consulte la Política de fin de vida útil (EOL) del agente de Go para obtener detalles sobre las versiones compatibles del agente de Go y los componentes de terceros.

September 7, 2022
Go agent v3.18.2

3.18.2

Added

  • Added WithDefaultFunctionLocation trace option. This allows the caller to indicate a fall-back function to use for CLM in case no other location was found first.
  • Added caching versions of the code-level metrics functions ThisCodeLocation and FunctionLocation , and trace options WithThisCodeLocation and WithFunctionLocation. These improve performance by caching the result of computing the source code location, and reuse that cached result on all subsequent calls.
  • Added a WithCodeLevelMetrics trace option to force the collection of CLM data even if it would have been excluded as being out of the configured scope. (Note that CLM data are never collected if CLM is turned off globally or if the WithoutCodeLevelMetrics option was specified for the same transaction.)
  • Added an exported CodeLevelMetricsScopeLabelToValue function to convert a list of strings describing CLM scopes in the same manner as the NEW_RELIC_CODE_LEVEL_METRICS_SCOPE environment variable (but as individual string parameters), returning the CodeLevelMetricsScope value which corresponds to that set of scopes.
  • Added a new CodeLevelMetricsScopeLabelListToValue function which takes a comma-separated list of scope names exactly as the NEW_RELIC_CODE_LEVEL_METRICS_SCOPE environment variable does, and returns the CodeLevelMetrics value corresponding to that set of scopes.
  • Added text marshaling and unmarshaling for the CodeLevelMetricsScope value, allowing the CodeLevelMetrics field of the configuration struct to be converted to or from JSON or other text-based encoding representations.

Changed

  • The WithPathPrefix trace option now takes any number of string parameters, allowing multiple path prefixes to be recognized rather than just one.
  • The FunctionLocation function now accepts any number of function values instead of just a single one. The first such parameter which indicates a valid function, and for which CLM data are successfully obtained, is the one which will be reported.
  • The configuration struct field PathPrefix is now deprecated with the introduction of a new PathPrefixes field. This allows for multiple path prefixes to be given to the agent instead of only a single one.
  • The NEW_RELIC_CODE_LEVEL_METRICS_SCOPE environment variable now accepts a comma-separated list of pathnames.

Fixed

  • Improved the implementation of CLM internals to improve speed, robustness, and thread safety.
  • Corrected the implementation of the WrapHandle and WrapHandleFunc functions so that they consistently report the function being invoked by the http framework, and improved them to use the new caching functions and ensured they are thread-safe.

This release fixes issue #557.

Compatibility Notice

As of release 3.18.0, the API was extended by allowing custom options to be added to calls to the Application.StartTransaction method and the WrapHandle and WrapHandleFunc functions. They are implemented as variadic functions such that the new option parameters are optional (i.e., zero or more options may be added to the end of the function calls) to be backward-compatible with pre-3.18.0 usage of those functions. This prevents the changes from breaking existing code for typical usage of the agent. However, it does mean those functions' call signatures have changed:

  • StartTransaction(string) -> StartTransaction(string, ...TraceOption)
  • WrapHandle(*Application, string, http.Handler) -> WrapHandle(*Application, string, http.Handler, ...TraceOption)
  • WrapHandleFunc(*Application, string, func(http.ResponseWriter, *http.Request)) -> WrapHandleFunc(*Application, string, func(http.ResponseWriter, *http.Request), ...TraceOption)

If, for example, you created your own custom interface type which includes the StartTransaction method or something that depends on these functions' exact call semantics, that code will need to be updated accordingly before using version 3.18.0 (or later) of the Go Agent.

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.
