Ruby agent v9.18.0

v9.18.0

• Feature: Add elasticsearch.capture_cluster_name configuration option

  A new configuration option, elasticsearch.capture_cluster_name, has been added to control capturing Elasticsearch cluster names. Cluster names are captured by default, but can now be disabled as needed. PR#3038

• Feature: Add support for sidekiq-delay_extensions

  Sidekiq delay extensions were removed from Sidekiq in 7.x and are now avaliable through the sidekiq-delay_extensions gem. Thanks to @sobrinho, the agent now has continued support for delay extensions.PR#3056

• Feature: Parallelize calls for vendor metadata

  Previously, the agent would make calls for vendor metadata in a serial fashion. This could lead to a delay in starting the agent. Now, the agent will make these calls in parallel, reducing the time it takes to start the agent. PR#3094

• Bugfix: Prevent a nil segment from causing errors in Net::HTTP instrumentation

  When using JRuby, a race condition can happen that causes the segment creation to fail and return nil. This would cause an error to occur when methods were later called on the nil segment. These methods will no longer be called if the segment is nil, preventing that error from occurring. PR#3046

• Bugfix: JRuby multithreading improvements

  Added some additional nil checks and mutexes to prevent issues when using the agent on JRuby with multiple threads. Thanks to @NC-piercej for bringing this to our attention Issue#3021 PR#3053

• Bugfix: Stop reporting rescued Sidekiq::OverLimit exceptions

  When Sidekiq's concurrent rate limiters encounter an OverLimit exception, Sidekiq typically handles this by re-enqueuing the job. Previously, all occurrences of Sidekiq::OverLimit were logged as errors in New Relic, even when Sidekiq's middleware resolved the exception. New Relic will no longer report errors that are handled by Sidekiq's own middleware. Thanks to @97jaz for reporting this issue. Issue#3037 PR#3047

• Bugfix: Protect against nil agents or health checks

  In some cases the agent or health checks may be nil when they are called. Safe navigation operators have been added for protection on those occasions. PR#3049

• Bugfix: Ignore Solid Queue ThreadError: queue empty error message by default

  When using the solid_queue gem, the agent previously generated excessive warn-level logs when the queue was empty. The agent now ignores queue empty error messages of the ThreadError class by default. This behavior can be adjusted using the error_collector.ignore_messages configuration option. PR#3060

• Bugfix: Refactor URI host handling to accommodate downcasing frozen strings

  When URI host string was frozen, a FrozenError would be raised when the agent attempted to downcase the host as part of its data normalization process. Now, the update is friendly for frozen strings. Thank you @pedrol3001 for your contribution! PR#3097
