To take the fullest advantage of New Relic's latest features, enhancements, and important security patches, New Relic strongly recommends that you follow the procedures to update your Ruby agent to the latest version. For additional information about specific agent updates, refer to the Ruby agent release notes.
Verify your Ruby agent versions
To determine which Ruby agent versions your apps currently use:
- From the account dropdown in the New Relic UI, select Account settings > Connected agents.
- Optional: Sort by Oldest agent version.
Update the agent
To update the agent:
Using Bundler: Run this command:
bundle update newrelic_rpm
Not using Bundler: Run this command:
gem update newrelic_rpm
For correct instrumentation:
- With JRuby versions 1.7+, use New Relic Ruby agent version 126.96.36.199 to 3.18.1
- With JRuby versions 9+, use New Relic Ruby agent version 188.8.131.52 or higher
Otherwise, if your application has no transactions and you are using JRuby, you will not be able to see your CPU metrics.
This was due to a bug in JRuby, where
Process.times returned wall clock time instead of elapsed CPU time. That bug was fixed as of New Relic’s Ruby agent 184.108.40.206 and JRuby 1.7.0.
Ruby agent versions not supported
End of life notification: As of January 26, 2015, New Relic will no longer accept data from Ruby agent versions earlier than 3.5.3.
These agent versions use an out-of-date protocol when communicating with New Relic's data collection services, and many also contain a potential security issue where they may incorrectly send sensitive data to the New Relic collector.
Ruby agent versions 3.18 or lower
With the release of Ruby agent version 4.0.0, some deprecated APIs were deleted. If you have used any of the deprecated methods with a version of Ruby agent 3.18 or lower, update your API with the recommended replacements.
