January 10
Ruby agent v9.7.0

중요

We recommend updating to the latest agent version as soon as it's available. If you can't upgrade to the latest version, update your agents to a version no more than 90 days old. Read more about keeping agents up to date.

See the New Relic Ruby agent EOL policy for information about agent releases and support dates.

v9.7.0

Version 9.7.0 introduces ViewComponent instrumentation, changes the endpoint used to access the cluster name for Elasticsearch instrumentation, removes the creation of the Ruby/Thread and Ruby/Fiber spans, and adds support for Falcon.

  • Feature: ViewComponent instrumentation

    ViewComponent is a now an instrumented library. PR#2367

  • Feature: Use root path to access Elasticsearch cluster name

    Previously, the agent used the cluster health endpoint (/_cluster/health) to access the cluster name. However, this has been found to make startup unstable for large clusters. Now, the agent uses the more performant root endpoint (/).

    Our thanks go to @erikkessler1, @gremerritt, and @joshbranham for reporting the issue, suggesting solutions, and testing them. Issue#2360 PR#2377

  • Feature: Remove base64 dependency, use direct calls to String methods

    In version 9.6.0, the agent required the Ruby base64 gem as a depdendency to prepare for deprecation warnings in Ruby 3.3 and the gem's removal from the Ruby standard libraries in 3.4. Including base64 as a dependency has caused problems with version resolution in some environments.

    To resolve this, the agent now directly calls the String methods used in the base64 library in the new NewRelic::Base64 module.

    Thank you, @Earlopain, for submitting this change. PR#2378

  • Feature: Add Falcon support

    The agent now supports the web server Falcon. PR#2383

  • Feature: Remove spans with name Ruby/Thread and Ruby/Fiber

    Due to the lack of helpful information and the confusion commonly caused by the spans named Ruby/Thread and Ruby/Fiber, these spans have been removed. However, the agents ability to monitor instrumented code running in a thread or fiber will remain unchanged. PR#2389

October 30, 2023
Ruby agent v9.6.0

중요

We recommend updating to the latest agent version as soon as it's available. If you can't upgrade to the latest version, update your agents to a version no more than 90 days old. Read more about keeping agents up to date.

See the New Relic Ruby agent EOL policy for information about agent releases and support dates.

v9.6.0

Version 9.6.0 adds instrumentation for Async::HTTP, Ethon, and HTTPX, adds the ability to ignore specific routes with Roda, gleans Docker container IDs from cgroups v2-based containers, records additional synthetics attributes, fixes an issue with Rails 7.1 that could cause duplicate log records to be sent to New Relic, fixes a deprecation warning for the Sidekiq error handler, adds additional attributes for OpenTelemetry compatibility, and resolves some technical debt, thanks to the community.

  • Feature: Add instrumentation for Async::HTTP

    The agent will now record spans for Async::HTTP requests. Versions 0.59.0 and above of the async-http gem are supported. PR#2272

  • Feature: Add instrumentation for Ethon

    Instrumentation has been added for the Ethon HTTP client gem. Versions 0.12.0 and above are supported. The agent will now record external request segments for invocations of Ethon::Easy#perform and Ethon::Multi#perform. NOTE: The Typhoeus gem is maintained by the same team that maintains Ethon and depends on Ethon for its functionality. To prevent duplicate reporting for each HTTP request, the Ethon instrumentation will be disabled when Typhoeus is detected. PR#2260

  • Feature: Add instrumentation for HTTPX

    The agent now offers instrumentation for the HTTP client HTTPX, provided the gem is at version 1.0.0 or above. PR#2278

  • Feature: Prevent the agent from starting in "rails" commands in Rails 7

    Previously, the agent ignored many Rails commands by default, such as rails routes, using Rake-specific logic. This was accomplished by setting these commands as default values for the config option autostart.denylisted_rake_tasks. However, Rails 7 no longer uses Rake for these commands, causing the agent to start running and attempting to record data when running these commands. The commands have now been added to the default value for the config option autostart.denylisted_constants, which will allow the agent to recognize these commands correctly in Rails 7 and prevent the agent from starting during ignored tasks. Note that the agent will continue to start-up when the rails server and rails runner commands are invoked. PR#2239

  • Feature: Glean Docker container ID for cgroups v2-based containers

    Previously, the agent was only capable of determining a host Docker container's ID if the container was based on cgroups v1. Now, containers based on cgroups v2 will also have their container IDs reported to New Relic. PR#2229.

  • Feature: Update events with additional synthetics attributes when available

    The agent will now record additional synthetics attributes on synthetics events if these attributes are available. PR#2203

  • Feature: Declare a gem dependency on the Ruby Base 64 gem 'base64'

    For compatibility with Ruby 3.4 and to silence compatibility warnings present in Ruby 3.3, declare a dependency on the base64 gem. The New Relic Ruby agent uses the native Ruby base64 gem for Base 64 encoding/decoding. The agent is joined by Ruby on Rails (rails/rails@3e52adf) and others in making this change in preparation for Ruby 3.3/3.4. PR#2238

  • Feature: Add Roda support for the newrelic_ignore* family of methods

    The agent can now selectively disable instrumentation for particular requests within Roda applications. Supported methods include:

    • newrelic_ignore: ignore a given route.
    • newrelic_ignore_apdex: exclude a given route from consideration in overall Apdex calculations.
    • newrelic_ignore_enduser: prevent automatic injection of the page load timing JavaScript when a route is rendered.

    For more information, see Roda Instrumentation. PR#2267

  • Feature: Add additional span attributes for OpenTelemetry compatibility

    For improved compatibility with OpenTelemetry's semantic conventions, the agent's datastore (for databases) and external request (for HTTP clients) segments have been updated with additional attributes.

    Datastore segments now offer 3 additional attributes:

    • db.system: The database system. For Ruby we use the database adapter name here.
    • server.address: The database host.
    • server.port: The database port.

    External request segments now offer 3 additional attributes:

    • http.request.method: The HTTP method (ex: 'GET')
    • server.address: The target host.
    • server.port: The target port.

    For maximum backwards compatibility, no existing attributes have been renamed or removed. PR#2283

  • Bugfix: Stop sending duplicate log events for Rails 7.1 users

    Rails 7.1 introduced the public API ActiveSupport::BroadcastLogger. This logger replaces a private API, ActiveSupport::Logger.broadcast. In Rails versions below 7.1, the agent uses the broadcast method to stop duplicate logs from being recoded by broadcasted loggers. Now, we've updated the code to provide a similar duplication fix for the ActiveSupport::BroadcastLogger class. PR#2252

  • Bugfix: Resolve Sidekiq 8.0 error handler deprecation warning

    Sidekiq 8.0 will require procs passed to the error handler to include three arguments: error, context, and config. Users running sidekiq/main would receive a deprecation warning with this change any time an error was raised within a job. Thank you, @fukayatsu for your proactive fix! PR#2261

  • Community: Resolve technical debt

    We also received some great contributions from community members to resolve some outstanding technical debt issues. Thank you for your contributions!

Ruby agent v9.5.0

중요

We recommend updating to the latest agent version as soon as it's available. If you can't upgrade to the latest version, update your agents to a version no more than 90 days old. Read more about keeping agents up to date.

See the New Relic Ruby agent EOL policy for information about agent releases and support dates.

v9.5.0

Version 9.5.0 introduces Stripe instrumentation, allows the agent to record additional response information on a transaction when middleware instrumentation is disabled, introduces new :'sidekiq.args.include' and :'sidekiq.args.exclude: configuration options to permit capturing only certain Sidekiq job arguments, updates Elasticsearch datastore instance metrics, and fixes a bug in NewRelic::Rack::AgentHooks.needed?.

  • Feature: Add Stripe instrumentation

    Stripe calls are now automatically instrumented. Additionally, new :'stripe.user_data.include' and :'stripe.user_data.exclude' configuration options permit capturing custom user_data key-value pairs that can be stored in Stripe events. No user_data key-value pairs are captured by default. The agent currently supports Stripe versions 5.38.0+. PR#2180

  • Feature: Report transaction HTTP status codes when middleware instrumentation is disabled

    Previously, when disable_middleware_instrumentation was set to true, the agent would not record the value of the response code or content type on the transaction. This was due to the possibility that a middleware could alter the response, which would not be captured by the agent when the middleware instrumentation was disabled. However, based on customer feedback, the agent will now report the HTTP status code and content type on a transaction when middleware instrumentation is disabled. PR#2175

  • Feature: Permit capturing only certain Sidekiq job arguments

    New :'sidekiq.args.include' and :'sidekiq.args.exclude' configuration options have been introduced to permit fine grained control over which Sidekiq job arguments (args) are reported to New Relic. By default, no Sidekiq args are reported. To report any Sidekiq options, the :'attributes.include' array must include the string 'jobs.sidekiq.args.*'. With that string in place, all arguments will be reported unless one or more of the new include/exclude options are used. The :'sidekiq.args.include' option can be set to an array of strings. Each of those strings will be passed to Regexp.new and collectively serve as an allowlist for desired args. For job arguments that are hashes, if a hash's key matches one of the include patterns, then both the key and its corresponding value will be included. For scalar arguments, the string representation of the scalar will need to match one of the include patterns to be captured. The :'sidekiq.args.exclude' option works similarly. It can be set to an array of strings that will each be passed to Regexp.new to create patterns. These patterns will collectively serve as a denylist for unwanted job args. Any hash key, hash value, or scalar that matches an exclude pattern will be excluded (not sent to New Relic). PR#2177

    newrelic.yml examples:

    Any string in the :'sidekiq.args.include' or :'sidekiq.args.exclude' arrays will be turned into a regular expression. Knowledge of Ruby regular expression support can be leveraged but is not required. If regular expression syntax is not used, inexact matches will be performed and the string "Fortune" will match both "Fortune 500" and "Fortune and Glory". For exact matches, use regular expression anchors.

    # Include any argument whose string representation matches either "apple" or "banana"
    # The "apple" pattern will match both "green apple" and "red apple"
    sidekiq.args.include:
    - apple
    - banana
    # Exclude any arguments that match either "grape", "orange", or "pear"
    sidekiq.args.exclude:
    - grape
    - orange
    - pear
    # Exclude any argument that is a 9 digit number
    sidekiq.args.exclude:
    - '\d{9}'
    # Include anything that starts with "blue" but exclude anything that ends in "green"
    sidekiq.args.include
    - '^blue'
    sidekiq.args.exclude
    - 'green$'
  • Bugfix: Update Elasticsearch datastore instance metric to use port instead of path

    Previously, the Elasticsearch datastore instance metric (Datastore/instance/Elasticsearch/<host>/*) used the path as the final value. This caused a metrics grouping issue for some users, as every document ID created a unique metric. Now, the datastore instance metric has been updated to use the port as the final value. This also has the benefit of being more accurate for datastore instance metrics, as this port is directly associated with the already listed host.

  • Bugfix: Resolve inverted logic of NewRelic::Rack::AgentHooks.needed?

    Previously, NewRelic::Rack::AgentHooks.needed? incorrectly used inverted logic. This has now been resolved, allowing AgentHooks to be installed when disable_middleware_instrumentation is set to true. PR#2175

v9.4.2

Version 9.4.2 of the agent re-addresses the 9.4.0 issue of NoMethodError seen when using the uppy-s3_multipart gem.

  • Bugfix: Resolve NoMethodError

    Ruby agent 9.4.1 attempted to fix a NoMethodError introduced in 9.4.0. A missing require prevented a method from scoping appropriately and has now been added. Thanks to @spickermann and @ColinOrr for working with us to get this resolved. PR#2167

See the New Relic Ruby agent EOL policy for information about agent releases and support dates.

v9.4.0

Version 9.4.0 of the agent adds Roda instrumentation, adds a new allow_all_headers configuration option to permit capturing all HTTP headers, introduces improved error tracking functionality by associating a transaction id with each error, and uses more reliable network timeout logic.

  • Feature: Add Roda instrumentation

    Roda is a now an instrumented framework. The agent currently supports Roda versions 3.19.0+. PR#2144

  • Feature: New allow_all_headers configuration option

    A new allow_all_headers configuration option brings parity with the Node.js agent to capture all HTTP request headers.

    This configuration option:

    • Defaults to false
    • Is not compatible with high-security mode
    • Requires Rack version 2 or higher (as does Ruby on Rails version 5 and above)
    • Respects all existing behavior for the attributes.include and attributes.exclude configuration options
    • Captures the additional headers as attributes prefixed with request.headers.

    This work was done in response to a feature request submitted by community member @jamesarosen. Thank you very much, @jamesarosen! Issue#1029

  • Feature: Improved error tracking transaction linking

    Errors tracked and sent to the New Relic errors inbox will now be associated with a transaction id to enable improved UI/UX associations between transactions and errors. PR#2035

  • Feature: Use Net::HTTP native timeout logic

    In line with current Ruby best practices, make use of Net::HTTP's own timeout logic and avoid the use of Timeout.timeout() when possible. The agent's data transmissions and cloud provider detection routines have been updated accordingly. PR#2147

See the New Relic Ruby agent EOL policy for information about agent releases and support dates.

v9.3.1

Version 9.3.1 of the agent fixes NewRelic::Agent.require_test_helper.

  • Bugfix: Fix NewRelic::Agent.require_test_helper

    Version 9.3.0 of the agent made a change to the files distributed with the gem. This change unintentionally broke the NewRelic::Agent.require_test_helper API by removing the test/agent_helper.rb file. The file has been added back to the gem. This change also removes the lib/new_relic/build.rb file from the list because it is no longer created with our current release process.

    Our thanks go to @ajesler for reporting this issue and writing a test for the bug. Issue#2113, PR#2115, Issue#2117, PR#2118

  • Source Documentation: update the Rack spec URL

    Community member @olleolleolle noticed that our source code was referencing a now defunct URL for the Rack specification and submitted PR#2121 to update it. He also provided a terrific recommendation that we automate the checking of links to proactively catch defunct ones in future. Thanks, @olleolleolle!

Ruby agent v9.3.0

중요

We recommend updating to the latest agent version as soon as it's available. If you can't upgrade to the latest version, update your agents to a version no more than 90 days old. Read more about keeping agents up to date.

See the New Relic Ruby agent EOL policy for information about agent releases and support dates.

v9.3.0

Version 9.3.0 of the agent adds log-level filtering, adds custom attributes for log events, and updates instrumentation for Action Cable. It also provides fixes for how Fiber args are treated, Code-Level Metrics, unnecessary files being included in the gem, and NewRelic::Agent::Logging::DecoratingFormatter#clear_tags! being incorrectly private.

  • Feature: Filter forwarded logs based on level

    Previously, all log events, regardless of their level, were forwarded to New Relic when log forwarding was enabled. Now, you may specify the lowest log level you'd like forwarded to New Relic.

    Configuration nameDefaultBehaviorValid values
    application_logging.forwarding.log_leveldebugSets the minimum log level for events forwarded to New Relicdebug, info, warn, error, fatal, unknown

    This setting uses Ruby's Logger::Severity constants integer values to determine precedence.

  • Feature: Custom attributes for logs

    You can now add custom attributes to log events forwarded to New Relic! You can pass these attributes using an API and/or a configuration option.

    Configuration nameDefaultBehavior
    application_logging.forwarding.custom_attributes{}A hash with key/value pairs to add as custom attributes to all log events forwarded to New Relic. If sending using an environment variable, the value must be formatted like: "key1=value1,key2=value2"

Call the API using NewRelic::Agent.add_custom_log_attributes and passing your attributes as a hash. For example, you could call: NewRelic::Agent.add_custom_log_attributes(dyno: ENV['DYNO'], pod_name: ENV['POD_NAME']), to add the attributes dyno and pod_name to your log events.

Attributes passed to the API or the configuration will be added to all log events.

Thanks to @rajpawar02 for raising this issue and @askreet for helping us with the solution. Issue#1141, PR#2084, PR#2087

  • Feature: Instrument transmit_subscription-related Action Cable actions

    This change subscribes the agent to the Active Support notifications for:

    • transmit_subscription_confirmation.action_cable
    • transmit_subscription_rejection.action_cable
  • Bugfix: Removed unwanted files from being included in file_list in gemspec

    Previously, the agent was including some files in the gem that were not needed but added to the size of the gem. These files will no longer be included. Thanks to @manuraj17 for the contribution! PR#2089

  • Bugfix: Report Code-Level Metrics for Rails controller methods

    Controllers in Rails automatically render views with names that correspond to valid routes. This means that a controller method may not have a corresponding method in the controller class. Code-Level Metrics now report on these methods and don't log false warnings. Thanks to @jcrisp for reporting this issue. PR#2061

  • Bugfix: Code-Level Metrics for ActiveRecord models

    Classes that inherit from ActiveRecord were not reporting Code-Level Metrics due to an error in the agent when identifying the class name. This has been fixed and Code-Level Metrics will now report for ActiveRecord models. Thanks to @abigail-rolling for reporting this issue. PR#2092.

  • Bugfix: Private method clear_tags! for NewRelic::Agent::Logging::DecoratingFormatter

    As part of a refactor included in a previous release of the agent, the method NewRelic::Agent::Logging::DecoratingFormatter#clear_tags! was incorrectly made private. This method is now public again. Thanks to @dark-panda for reporting this issue. PR#

  • Bugfix: Fix the way args are handled for Fibers

    Previously, the agent treated Fiber args the same as it was treating Thread args, which is not correct. Args are passed to Fiber#resume, and not Fiber.new. This has been fixed, and the agent will properly preserve args for both Fiber and Thread classes. This also caused an error to occur when using Async 2.6.2, due to mismatching initalize definitions for Fiber prepended modules. This has been fixed as well. Thanks to @travisbell for bringing this to our attention. PR#2083

Ruby agent v9.2.1

중요

We recommend updating to the latest agent version as soon as it's available. If you can't upgrade to the latest version, update your agents to a version no more than 90 days old. Read more about keeping agents up to date.

See the New Relic Ruby agent EOL policy for information about agent releases and support dates.

v9.2.1

Version 9.2.1 fixes a bug causing the agent to continue storing data on finished transactions, and a bug preventing errors from being expected.

  • Bugfix: Finished transactions continue to store data on different threads

    Previously, when a new thread was spawned the agent would continue using the current transaction to record data on, even if this transaction had finished already in a different thread. Now the agent will only use the current transaction in the new thread if it is not yet finished. Thank you to @fcheung for reporting this bug and providing us with an extremely helpful reproduction to debug. PR#1969

  • Bugfix: Expected Errors passed to notice_error are expected again

    A bug was introduced in 9.1.0 that caused to agent not to mark errors as expected if the error was passed in to notice_error using the expected: true parameter. This has been fixed and errors will now be marked as expected, as expected. Thank you very much to @eiskrenkov for finding this bug and contributing a fix for it! PR#1954
