3.20.1

Importante

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

POR GENTILEZA, LEIA estas alterações e verifique as configurações para garantir que o aplicativo se comporte conforme o pretendido. Esta versão altera alguns comportamentos padrão no agente Go.

Adicionado

  • O recurso Métricas de Dependência de Módulo foi adicionado. Isso coleta a lista de módulos importados para o aplicativo, para auxiliar no gerenciamento das dependências do aplicativo, permitindo detecção e resposta a vulnerabilidades mais fáceis, etc.

    • Este recurso é ativado por padrão, mas pode ser desativado incluindo explicitamente ConfigModuleDependencyMetricsEnable(false) no aplicativo, ou definindo a variável de ambiente equivalente ou o campo Config diretamente.
    • Os módulos podem ser explicitamente excluídos do relatório por meio da opção ConfigModuleDependencyMetricsIgnoredPrefixes.
    • Os nomes de módulos excluídos podem ser ocultados por meio da opção ConfigModuleDependencyMetricsRedactIgnoredPrefixes. Isso está habilitado por padrão.

  • Application Log Forwarding estará ahora HABILITADO de forma predeterminada.

    • O encaminhamento automático de logs de aplicativo agora está habilitado por padrão. Isso significa que os frameworks de log envolvidos com uma das integrações logcontext-v2 enviarão automaticamente logs de aplicativo enriquecidos para a New Relic com esta versão do agente. Para saber mais sobre este recurso, consulte a documentação de logs contextualizados do APM. Para opções de configuração adicionais, consulte a documentação de logs contextualizados do Go. Para saber como ativar ou desativar a ingestão de logs por conta, consulte nossa documentação para desabilitar o registro automático por meio da interface ou API.
    • Caso esteja usando uma extensão logcontext-v2, mas não queira que o agente encaminhe os logs automaticamente, por gentileza, configure ConfigAppLogForwardingEnabled(false) no aplicativo.
    • Variáveis de ambiente foram adicionadas para todas as opções de configuração de logging de aplicativo:
      • 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 do limite de eventos personalizados

Mudado

  • Os seguintes nomes foram alterados para serem consistentes com seu uso e outros nomes de identificador relacionados. Os nomes antigos permanecem para compatibilidade com versões anteriores, mas o novo código deve usar os novos nomes.

    • 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

  • Ao excluir informações relatadas do CodeLevelMetrics por meio dos campos de configuração IgnoredPrefixes ou PathPrefixes (por exemplo, especificando ConfigCodeLevelMetricsIgnoredPrefixes ou ConfigCodeLevelMetricsPathPrefixes), os nomes dos prefixos ignorados e os prefixos de caminho configurados agora podem ser ocultados das informações de configuração do agente enviadas para a New Relic.

    • Essa ocultação é ativada por padrão, mas pode ser desativada fornecendo um valor false para ConfigCodeLevelMetricsRedactPathPrefixes ou ConfigCodeLevelMetricsRedactIgnoredPrefixes, ou definindo os campos Config correspondentes ou variáveis de ambiente como false.

Fixo

  • #583: corrigido um bug no zerologWriter em que campos separados por vírgula na mensagem do log confundiam o analisador JSON e podiam causar pânicos.

Declaração de apoio

A New Relic recomenda atualizar o agente regularmente para garantir a obtenção dos recursos e benefícios de desempenho mais recentes. Além disso, versões mais antigas não serão mais suportadas quando atingirem o fim da vida útil.

Também recomendamos usar a versão mais recente da linguagem Go. No mínimo, não se deve usar nenhuma versão do Go mais antiga do que a suportada pela própria equipe do Go.

Recomendamos consultar a Política de EOL do agente Go para obter detalhes sobre as versões suportadas do agente Go e componentes de terceiros.

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.

See the Go Agent EOL Policy for details about supported versions of the Go Agent and third-party components.
