Ruby agent v4.7.0.339

Notes

• Expected Error API

  The agent now sends up error.expected as an intrinsic attribute on error events and error traces. When you pass expected: true to the notice_error method, both Insights and APM will indicate that the error is expected.

• Typhoeus Hydra Instrumentation

  The agent now has request level visibility for HTTP requests made using Typhoeus Hydra.

• Total Time Metrics are Recorded

  The agent now records Total Time metrics. In an application where segments execute concurrently, the total time can exceed the wall-clock time for a transaction. Users of the new Typhoeus Hydra instrumentation will notice this as changes on the overview page. Immediately after upgrading there will be an alert in the APM dashboard that states: "There are both old and new time metrics for this time window". This indicates that during that time window, some transactions report the total time metrics, while others do not. The message will go away after waiting for enough time to elapse and / or updating the time window.

• Add :message category to set_transaction_name public API method

  The agent now permits the :message category to be passed into the public API method set_transaction_name, which will enable the transaction to be displayed as a messaging transaction.

• Create prepend_active_record_instrumentation config option

  Users may now set the prepend_active_record_instrumentation option in their agent config to install Active Record 3 or 4 instrumentation using Module.prepend rather than alias_method.

• Use Lazy load hooks for ActionController::Base and ActionController::API

  The agent now uses lazy load hooks to hook on ActionController::Base and ActionController::API. Thanks Edouard Chin for the contribution!

• Use Lazy load hooks for ActiveRecord::Base and ActiveRecord::Relation

  The agent uses lazy load hooks when recording supportability metrics for ActiveRecord::Base and ActiveRecord::Relation. Thanks Joseph Haig for the contribution!

• Check that Rails::VERSION is defined instead of just Rails

  The agent now checks that Rails::VERSION is defined since there are cases where Rails is defined but Rails::VERSION is not. Thanks to Alex Riedler and nilsding for the contribution!

• Support fast RPC/direct reply-to in RabbitMQ

  The agent can now handle the pseudo-queue 'amq.rabbitmq.reply-to' in its Bunny instrumentation. Previously, using fast RPC led to a NoMethodError because the reply-to queue was expected to be a Queue object instead of a string.
