To take full advantage of New Relic's latest features, enhancements, and important security patches, we recommend you update your Ruby agent to the latest version. For additional information about specific agent updates, refer to the Ruby agent release notes.
To determine which Ruby agent versions your apps currently use:
- In New Relic, from the account dropdown, select Account settings > Connected agents.
- Optional: Sort by Oldest agent version.
To update the Ruby 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 or higher, use New Relic Ruby agent version 220.127.116.11 to 3.18.1.
- With JRuby versions 9 or higher, use New Relic Ruby agent version 18.104.22.168 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 22.214.171.124 and JRuby 1.7.0.
End of life notification: As of January 26, 2015, New Relic will no longer accept data from Ruby agent versions earlier than 3.9.6.
These agent versions use an out-of-date protocol when communicating with New Relic's data collection services. In addition, many of these versions contain a potential security issue where they may incorrectly send sensitive data to the New Relic collector.
If you are updating from an older agent version, including major version jumps, review the following list for changes in functionality.
