We just released AppSignal for Ruby gem version 2.8.0 which improves memory host metrics reporting on containers, supports JRuby on Alpine Linux and improves the diagnostics reports we use to debug any issue you may be having.
Container memory metrics
On most container systems our current method of reporting host metrics is inaccurate. Read the issue report for more details.
In order to report accurate metrics we've been working to improve our reporting for container host metrics. First to be fixed are memory metrics, so you can track if your 512MB container is running out of memory or not.
Support for other metrics such as CPU and disk IO will follow in future releases.
JRuby support for Alpine Linux
JRuby is now supported on Alpine Linux. Due to an improvement to our build process we can now support this combination, building dynamic libraries for our extension to be used on Alpine Linux.
Diagnostic improvements
Support is done by all of AppSignal's developers do support on a weekly basis. To optimize every support request we've been working to improve our diagnostics report by adding more relevant data to the report based on previously encountered issues.
We've also been working on adding a validator to the diagnostic report. This is still a work in progress at time of writing, but the Ruby gem will already print a link to the validator on AppSignal.com. We hope that in time everyone can use this validator as well to debug most common issues.
Send a report by using the diagnose command line tool:
