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.
