The Ruby agent provides support for the mongo gem, versions 1.8 and 1.9! Mongo calls are captured for transaction traces along with their parameters, and time spent in Mongo shows up on the Database tab.
Support for more Mongo gems and more UI goodness will be coming, so watch http://docs.newrelic.com/docs/ruby/mongo for up-to-date status.
Harvest thread restarts for forked and daemonized processes
Historically framework specific code was necessary for the Ruby agent to successfully report data after an app forked or daemonized. Gems or scripts with daemonizing modes had to wait for agent support or find workarounds.
With 3.7.1 setting
restart_thread_in_children: truein your newrelic.yml automatically restarts the agent in child processes without requiring custom code. For now the feature is opt-in, but future releases may default it on.
Fix for missing HTTP time
The agent previously did not include connection establishment time for outgoing Net::HTTP requests. This has been corrected, and reported HTTP timings should now be more accurate.
