New Relic v3.7.1 Release Notes

    • MongoDB support

    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: true in 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.

    • Fix for Mongo ensure_index instrumentation (3.7.1.182)

    The Mongo instrumentation for ensure_index in 3.7.1.180 was not properly calling through to the uninstrumented version of this method. This has been fixed in 3.7.1.182. Thanks to Yuki Miyauchi for the fix!

    • Correct first reported metric timespan for forking dispatchers (3.7.1.188)

    The first time a newly-forked process (in some configurations) reported metric data, it would use the startup time of the parent process as the start time for that metric data instead of its own start time. This has been fixed.
