New Relic v3.5.8 Release Notes
-
Key Transactions
The Ruby agent now supports Key Transactions! Check out more details on the feature at https://newrelic.com/docs/site/key-transactions
Ruby 2.0
The Ruby agent is compatible with Ruby 2.0.0 which was just released.
Improved Sinatra instrumentation
Several cases around the use of conditions and pass in Sinatra are now better supported by the Ruby agent. Thanks Konstantin for the help!
Outbound HTTP headers
Adds a 'X-NewRelic-ID' header to outbound Net::HTTP requests. This change helps improve the correlation of performance between services in a service- oriented architecture for a forthcoming feature. In the meantime, to disable the header, set this in your newrelic.yml:
cross_application_tracer: enabled: false
Automatically detect Resque dispatcher
The agent does better auto-detection for the Resque worker process. This should reduce the need to set NEW_RELIC_DISPATCHER=resque directly.
