v9.14.0

Version 9.14.0 adds Apache Kafka instrumentation for the rdkafka and ruby-kafka gems, introduces a configuration-based, automatic way to add custom instrumentation method tracers, correctly captures MIME type for ActionDispatch 7.0+ requests, properly handles Boolean coercion for newrelic.yml configuration, fixes a JRuby bug in the configuration manager, fixes a bug related to Bundler.rubygems.installed_specs, and fixes a bug to make the agent compatible with ViewComponent v3.15.0+.

• Feature: Add Apache Kafka instrumentation for the rdkafka and ruby-kafka gems

  The agent now has instrumentation for both the rdkafka and ruby-kafka gems. The agent will record transactions and message broker segments for produce and consume calls made using these gems. PR#2824 PR#2842

• Feature: Add a configuration option to permit custom method tracers to be defined automatically

  A new :automatic_custom_instrumentation_method_list configuration parameter has been added to permit the user to define a list of fully qualified (namespaced) Ruby methods for the agent to automatically add custom instrumentation for without requiring any code modifications to be made to the classes that define the methods.

  The list should be an array of CLASS#METHOD (for instance methods) and/or CLASS.METHOD (for class methods) strings.

  Use fully qualified class names (using the :: delimiter) that include any module or class namespacing.

  Here is some Ruby source code that defines a render_png instance method for an Image class and a notify class method for a User class, both within a MyCompany module namespace:

  module MyCompany
    class Image
      def render_png
        # code to render a PNG
      end
    end
  
    class User
      def self.notify
        # code to notify users
      end
    end
  end

  Copiar

  Given that source code, the newrelic.yml config file might request instrumentation for both of these methods like so:

  automatic_custom_instrumentation_method_list:
    - MyCompany::Image#render_png
    - MyCompany::User.notify

  Copiar

  That configuration example uses YAML array syntax to specify both methods. Alternatively, a comma-delimited string can be used instead:

  automatic_custom_instrumentation_method_list: 'MyCompany::Image#render_png, MyCompany::User.notify'

  Copiar

  Whitespace around the comma(s) in the list is optional. When configuring the agent with a list of methods via the NEW_RELIC_AUTOMATIC_CUSTOM_INSTRUMENTATION_METHOD_LIST environment variable, this comma-delimited string format should be used:

  export NEW_RELIC_AUTOMATIC_CUSTOM_INSTRUMENTATION_METHOD_LIST='MyCompany::Image#render_png, MyCompany::User.notify'

  PR#2851

• Feature: Collect just MIME type for ActionDispatch 7.0+ requests

  Rails 7.0 introduced changes to the behavior of ActionDispatch::Request#content_type, adding extra request-related details the agent wasn't expecting to collect. Additionally, the agent's use of content_type was triggering deprecation warnings. The agent now uses ActionDispatch::Request#media_type to capture the MIME type. Thanks to @internethostage for letting us know about this change. Issue#2500 PR#2855

• Bugfix: Corrected Boolean coercion for newrelic.yml configuration

  Previously, any String assigned to New Relic configurations expecting a Boolean value were evaluated as true. This could lead to unexpected behavior. For example, setting application_logging.enabled: 'false' in newrelic.yml would incorrectly evaluate to application_logging.enabled: true due to the truthy nature of Strings.

  Now, the agent strictly interprets Boolean configuration values. It recognizes both actual Boolean values and certain Strings/Symbols:

  • 'true', 'yes', or 'on' (evaluates to true)
  • 'false', 'no', or 'off' (evaluates to false)

  Any other inputs will revert to the setting's default configuration value. PR#2847

• Bugfix: JRuby not saving configuration values correctly in configuration manager

  Previously, a change made to fix a different JRuby bug caused the agent to not save configuration values correctly in the configuration manager when running on JRuby. This has been fixed. PR#2848

• Bugfix: Update condition to verify Bundler.rubygems.installed_specs is available

  To address a recent Bundler deprecation warning, we started using Bundler.rubygems.installed_specs instead of Bundler.rubygems.all_specs in environments that seemed appropriate. We discovered the version constraint we used was too low. Now, rather than check the version, we check for the method using respond_to?. PR#2853

• Bugfix: Support view_component v3.15.0+

  Previously the agent had been making use of a private API to obtain a component identifier value. This private API was dropped in v3.15.0 of view_component, resulting in errors from the New Relic Ruby agent's continued attempts to use it. Many thanks to community member @navidemad for bringing this issue to our attention and supplying a bugfix with PR#2870.

v9.13.0

A versão 9.13.0 aprimora o suporte para funções do AWS Lambda, adiciona instrumentação experimental do OpenSearch, atualiza a detecção de framework, silencia um aviso de descontinuação do Bundler, corrige a detecção do despachante do Falcon, corrige um bug com a instalação da instrumentação do Redis e resolve um problema de simultaneidade específico do JRuby.

• Recurso: aprimorar a instrumentação da função do AWS Lambda

Quando utilizado por meio da mais recente camada Ruby do New Relic para AWS Lambda, o agente agora oferece suporte aprimorado para a instrumentação da função do AWS Lambda.

• A instrumentação do agente para funções do AWS Lambda agora oferece suporte a distributed tracing.

• As invocações acionadas pela web agora são identificadas como sendo baseadas na "web" quando uma chamada do API Gateway está envolvida, com suporte para as versões 1.0 e 2.0 do API Gateway.

• As chamadas baseadas na web têm o método HTTP, o URI e o código de status registrados.

• O agente agora reconhece e informa sobre 12 recursos distintos da AWS que são capazes de acionar a invocação de uma função do Lambda: ALB, API Gateway V1, API Gateway V2, CloudFront, CloudWatch Scheduler, DynamoStreams, Firehose, Kinesis, S3, SES, SNS e SQS.

• O tipo do recurso acionador e seu ARN serão registrados para cada recurso e, para muitos deles, atributos extras específicos do recurso também serão registrados. Por exemplo, invocações da função do Lambda acionadas pela atividade do bucket do S3 agora resultarão no registro do nome do bucket do S3. PR#2811

• Recurso: adicionar instrumentação experimental do OpenSearch

  O agente agora instrumentará automaticamente a gem opensearch-ruby. Estamos marcando esta instrumentação como experimental porque é necessário mais trabalho para testá-la totalmente. A instrumentação do OpenSearch fornece telemetria semelhante à do Elasticsearch. Agradecemos a @Earlopain por relatar o problema e a @praveen-ks por um rascunho inicial da instrumentação. Issue n.º 2228 PR n.º 2796

• Recurso: melhorar a precisão de detecção de framework para Grape e Padrino

  Anteriormente, os aplicativos que usavam o framework Grape definiam ruby como seu framework no Relatório de Ambiente. Agora, os aplicativos Grape serão definidos como grape. Da mesma forma, os aplicativos que usam o framework Padrino seriam definidos como sinatra. Agora, eles serão definidos como padrino. Isso ajudará nas verificações de compatibilidade do agente de segurança do New Relic. Agradecemos a @prateeksen por fazer essa alteração. Issue#2777 PR#2789

• Recurso: silenciar o aviso de descontinuação do Bundler all_specs

  Bundler.rubygems.all_specs foi descontinuado em favor de Bundler.rubygems.installed_specs nas versões 2+ do Bundler, fazendo com que o agente emitisse avisos de descontinuação. O método foi atualizado quando o Bundler 2+ é detectado e os avisos agora são silenciados. Agradecemos a @jcoyne por relatar este problema. Issue#2733 PR#2823

• Correção de bug: corrigir a detecção do dispatcher do Falcon

  Anteriormente, tentamos usar o espaço de objetos para determinar se o servidor web Falcon estava em uso. No entanto, o Falcon não é adicionado ao espaço de objetos até que o relatório de ambiente seja gerado, resultando em um dispatcher nil. Agora, revertemos para uma estratégia anterior que descobria o dispatcher usando File.basename. Agradecemos a @prateeksen por relatar este problema e investigar a questão. Issue#2778 PR#2795

• Correção de bug: correção de um erro de instrumentação do Redis quando Redis::Cluster::Client está presente

  A instrumentação do Redis continha anteriormente um bug que causava um erro quando Redis::Cluster::Client estava presente, devido ao uso de um return do Ruby fora de um método. Agradecemos muito ao @jdelStrother não apenas por relatar este bug, mas também por nos indicar a causa raiz. Issue#2814 PR#2816

• Correção de bug: Resolver problema de concorrência do JRuby com o acesso à configuração de aplicar hash

  A classe de configuração interna do agente mantém um hash que ocasionalmente é reconstruído. Durante a reconstrução, certos valores de instrumentação previamente determinados de forma dinâmica são preservados para o benefício do agente de segurança New Relic Ruby. Após relatos de clientes do JRuby sobre problemas de concorrência relacionados ao hash sendo acessado enquanto era modificado, duas correções separadas foram incluídas na lógica de reconstrução do hash anteriormente: uma operação Hash#dup e um bloco synchronize do. Mas erros ainda foram relatados. Nós mesmos continuamos incapazes de reproduzir esses erros de concorrência, apesar de usarmos exatamente as mesmas versões do JRuby e de todos os softwares relatados. Após confirmar que o código de acesso ao hash em questão é necessário apenas para o agente de segurança Ruby (que opera apenas em ambientes dedicados de testes de segurança de não produção), introduzimos uma nova correção para clientes do JRuby que simplesmente ignorará o código problemático quando o JRuby estiver em uso, mas o agente de segurança não. PR#2798

v9.12.0

Version 9.12.0 adds support for the newrelic_security agent, introduces instrumentation for the LogStasher gem, improves instrumentation for the redis-clustering gem, and updates the Elasticsearch instrumentation to only attempt to get the cluster name once per client, even if it fails.

• Feature: Add support for the newrelic_security agent

  New Relic Interactive Application Security Testing (IAST) can help you prevent cyberattacks and breaches on your applications by probing your running code for exploitable vulnerabilities.

  The newrelic_security gem provides this feature for Ruby. It depends on newrelic_rpm. This is the first version of newrelic_rpm compatible with newrelic_security.

  At this time, the security agent is intended for use only within a dedicated security testing environment with data that can tolerate modification or deletion. The security agent is available as a separate Ruby gem, newrelic_security. It is recommended that this separate gem only be introduced to a security testing environment by leveraging Bundler grouping like so:

  # Gemfile
    gem 'newrelic_rpm'               # New Relic APM observability agent
    gem 'newrelic-infinite_tracing'  # New Relic Infinite Tracing
  
    group :security do
      gem 'newrelic_security', require: false        # New Relic security agent
    end

  Copiar

  In order to run the security agent, you need to update your configuration. At a minimum, security.agent.enabled and security.enabled must be set to true. They are false by default. Similar to the gem installation, we recommend you set these configurations for a special security testing environment only.

  Here's an example using newrelic.yml:

  common: &default_settings
      license_key: <%= ENV['NEW_RELIC_LICENSE_KEY'] %>
      app_name: "Example app"
  
    development:
      <<: *default_settings
      app_name: <%= app_name %> (Development)
  
    security:
      <<: *default_settings
      security.enabled: true
      security.agent.enabled: true
  
    production:
      <<: *default_settings

  Copiar

  The following configuration relate to the newrelic_security gem:

  Configuration name	Default	Behavior
  security.agent.enabled	false	If true, the security agent is loaded (a Ruby 'require' is performed)
  security.enabled	false	If true, the security agent is started (the agent runs in its event loop)
  security.mode	'IAST'	Defines the mode for the security agent to operate in. Currently only 'IAST' is supported
  security.validator_service_url	'wss://csec.nr-data.net'	Defines the endpoint URL for posting security related data
  security.detection.rci.enabled	true	If true, enables RCI (remote code injection) detection
  security.detection.rxss.enabled	true	If true, enables RXSS (reflected cross-site scripting) detection
  security.detection.deserialization.enabled	true	If true, enables deserialization detection
  security.application_info.port	nil	An Integer representing the port the application is listening on. This setting is mandatory for Passenger servers. Other servers should be detected by default.

• Feature: Add instrumentation for LogStasher

  The agent will now record logs generated by LogStasher. Versions 1.0.0 and above of the LogStasher gem are supported. PR#2559

• Feature: Add instrumentation for redis-clustering

  Version 5.x of the redis gem moved cluster behavior into a different gem, redis-clustering. This gem can access instrumentation registered through RedisClient::Middleware. Previously, the agent only instrumented the call_pipelined method through this approach, but now users of the redis-clustering gem will also have instrumentation registered for connect and call methods. In addition, the way the database_name attribute is set for Redis datastore spans is now compatible with all versions of Redis supported by the New Relic Ruby agent. Thank you, @praveen-ks for bringing this to our attention. Issue#2444 PR#2720

• Bugfix: Update Elasticsearch instrumentation to only attempt to get the cluster name once per client

  Previously, the agent would attempt to get the cluster name every time a call was made if it was not already captured. This could lead to a large number of failures if the cluster name could not be retrieved. Now, the agent will only attempt to get the cluster name once per client, even if it fails. Thank you, @ascoppa for bringing this to our attention. Issue#2730 PR#2743

• Feature: Produce metrics for 4 additional Action Controller Rails notifications

  Four additional Action Controller related Rails notifications are now subscribed to by the agent to produce telemetry. These 4 are exist_fragment?, expire_fragment, read_fragment, and write_fragment. As with instrumentation for Action Controller itself, these notifications are enabled by default and can be disabled by setting :disable_action_controller to true in the agent's newrelic.yml configuration file. PR#2745

v9.11.0

Version 9.11.0 introduces instrumentation for the aws-sdk-sqs gem, fixes a bug related to expected errors not bearing a "true" value for the "expected" attribute if expected as a result of an HTTP status code match and changes the way Stripe instrumentation metrics are named to prevent high-cardinality issues.

• Feature: Add instrumentation for SQS

  The agent has added instrumentation for the aws-sdk-sqs gem. The agent will now record message broker spans for SQS client calls made with the aws-sdk-sqs gem. PR#2679

• Bugfix: HTTP status code based expected errors will now have an "expected" value of "true"

  Previously when an error was treated as expected by the agent as a result of a matching HTTP status code being found in the :'error_collector.expected_status_codes' configuration setting, the error would not appear with an "expected" attribute value of "true" in the errors in the errors inbox. PR#2710

• Bugfix: Stripe metric names will no longer include full request paths to limit the unique name count

  The Stripe instrumentation introduced in agent version v9.5.0 produced instrumentation metric names that used the full Stripe request path. For any significant Stripe usage, this could quickly lead to very large number of distinct metric names. Now only the API version and the category part of the request path are included in the metric name which still includes the "Stripe" opener and method (ex: "get") closer. Thanks to @jdelStrother and @jsneedles for bringing this issue to our attention and providing terrific information explaining the problem and potential paths to resolution. PR#2716

v9.10.2

Version 9.10.2 fixes a bug related to the new DynamoDB instrumentation and removes Rails::Command::RakeCommand from the default list of denylisted constants.

• Bugfix: DynamoDB instrumentation logging errors when trying to get account_id

  When trying to access data needed to add the account_id to the DynamoDB span, the agent encountered an error when certain credentials classes were used. This has been fixed. Thanks to @kichik for bringing this to our attention. PR#2864

• Bugfix: Remove Rails::Command::RakeCommand from the default list of autostart.denylisted_constants

  The default value for the autostart.denylisted_constants configuration was changed in 9.10.0 to include Rails::Command::RunnerCommand and Rails::Command::RakeCommand. The inclusion of Rails::Command::RakeCommand prevented the agent from starting automatically when Solid Queue was started using bin/rails solid_queue:start. We recognize there are many commands nested within Rails::Command::RakeCommand and have decided to remove it from the default list. We encourage users who do not want the agent to run on Rails::Command::RakeCommand to add the constant to their configuration. This can be accomplished by adding the following to your newrelic.yml file:

  autostart.denylisted_constants: "Rails::Command::ConsoleCommand,Rails::Command::CredentialsCommand,Rails::Command::Db::System::ChangeCommand,Rails::Command::DbConsoleCommand,Rails::Command::DestroyCommand,Rails::Command::DevCommand,Rails::Command::EncryptedCommand,Rails::Command::GenerateCommand,Rails::Command::InitializersCommand,Rails::Command::NotesCommand,Rails::Command::RakeCommand,Rails::Command::RoutesCommand,Rails::Command::RunnerCommand,Rails::Command::SecretsCommand,Rails::Console,Rails::DBConsole"

  Thank you, @edariedl, for reporting this issue. Issue#2677 PR#2694

v9.10.1

• Bugfix: Incompatibility with Bootstrap

Version 9.10.1 fixes an incompatibility between the agent and the Bootstrap gem caused by agent v9.10.0's introduction of a lib/bootstrap.rb file. Thank you to @dorner for reporting the bug and identifying the 'bootstrap' name collision as the root cause. BUG#2675 PR#2676

v9.10.0

Version 9.10.0 introduces instrumentation for DynamoDB, adds a new feature to automatically apply nonces from the Rails content security policy, fixes a bug that would cause an expected error to negatively impact a transaction's Apdex, and fixes the agent's autostart logic so that by default rails runner and rails db commands will not cause the agent to start.

• Feature: Add instrumentation for DynamoDB

  The agent has added instrumentation for the aws-sdk-dynamodb gem. The agent will now record datastore spans for DynamoDB client calls made with the aws-sdk-dynamodb gem. PR#2642

• Feature: Automatically apply nonces from the Rails content security policy

  To auto-inject browser monitoring with the New Relic Ruby agent, you either need to set your content security policy to 'unsafe-inline' or provide a nonce. Previously, the only way to provide a nonce was by using the NewRelic::Agent.browser_timing_header API. Now, when a Rails application uses the content security policy configuration to add a nonce, the nonce will be automatically applied to the browser agent. A new configuration option, browser_monitoring.content_security_policy_nonce, toggles this feature. It is on by default. Thank you @baldarn for submitting this feature! PR#2544

• Bugfix: Expected errors related to HTTP status code, class, and message won't impact Apdex

  The agent is supposed to prevent observed application errors from negatively impacting Apdex if the errors are either ignored or expected. There are two ways for the agent to expect an error: via the notice_error API receiving an expected: true argument or via matches made against user-configured lists for expected HTTP status codes (:'error_collector.expected_status_codes'), expected error classes (:'error_collector.expected_classes'), or expected error messages (:'error_collector.expected_messages'). Previously, only errors expected via the notice_error API were correctly prevented from impacting Apdex. Expected errors set by configuration incorrectly impacted Apdex. This behavior has been fixed and now both types of expected errors will correctly not impact Apdex. Thanks very much to @florianpilz for bringing this issue to our attention. PR#2619

• Bugfix: Do not start the agent automatically when rails runner or rails db commands are run

  PR#2239 taught the agent how to recognize bin/rails based contexts that it should not automatically start up in. But bin/rails runner and bin/rails db commands would still see the agent start automatically. Those 2 contexts will now no longer see the agent start automatically. Thank you to @jdelStrother for both bringing the bin/rails context to our attention and for letting us know about the bin/rails runner and bin/rails db outliers that still needed fixing. PR#2623

  Older agent versions that are still supported by New Relic can update to the new list of denylisted constants by having the following line added to the newrelic.yml configuration file:

  autostart.denylisted_constants: "Rails::Command::ConsoleCommand,Rails::Command::CredentialsCommand,Rails::Command::Db::System::ChangeCommand,Rails::Command::DbConsoleCommand,Rails::Command::DestroyCommand,Rails::Command::DevCommand,Rails::Command::EncryptedCommand,Rails::Command::GenerateCommand,Rails::Command::InitializersCommand,Rails::Command::NotesCommand,Rails::Command::RakeCommand,Rails::Command::RoutesCommand,Rails::Command::RunnerCommand,Rails::Command::SecretsCommand,Rails::Console,Rails::DBConsole"

v9.9.0

Version 9.9.0 introduces support for AWS Lambda serverless function observability, adds support for Elasticsearch 8.13.0, and adds the 'request.temperature' attribute to chat completion summaries in ruby-openai instrumentation.

• Feature: Serverless Mode for AWS Lambda

  The Ruby agent is now capable of operating in a quick and light serverless mode suitable for observing AWS Lambda function invocations. For serverless use, the agent is delivered by a New Relic Lambda layer that can be associated with a Lambda function. All reported data will appear in New Relic's dedicated serverless UI views. Only AWS based Lambda functions are supported for now, though support for other cloud hosted serverless offerings may be added in future depending on Ruby customer demand. The serverless functionality is only intended for use with the official New Relic Ruby layers for Lambda. Any existing workflows that involve the manual use of the Ruby agent in an AWS Lambda context without a New Relic layer should not be impacted.

• Feature: Add support for Elasticsearch 8.13.0

  Elasticsearch 8.13.0 increased the number of arguments used in the method the agent instruments, Elastic::Transport::Client#perform_request. Now, the agent supports a variable number of arguments for the instrumented method to prevent future ArgumentErrors.

• Bugfix: Add 'request.temperature' to ruby-openai chat completion summaries

  Previously, the agent was not reporting the request.temperature attribute on LlmChatCompletionSummary events through ruby-openai instrumentation. We are now reporting this attribute.
