[Ruby] No known dispatcher detected message in logs

I’m seeing this message in my rails application logs despite adding dispatcher: puma in my newrelic.yml file. Data is showing up in New Relic. Is there more configuration required?

Hi, @erica1

Something’s not quite right there. If you set the dispatcher option to “puma” then it should definitely not be logging “No known dispatcher detected” to the log file.

Any chance Server Side Config is enabled for your application and environment?

Also, check the spelling of the option and nesting level where it appears in the newrelic.yml file.

The code picking up the dispatcher setting is pretty straightforward!
