AppSignal for Ruby

AppSignal supports the Ruby language with a Ruby gem. The gem supports many frameworks and gems out-of-the-box. Some gems and frameworks might require some custom instrumentation.

It's also supported to add custom instrumentation to your application and get even more insights into the performance of your code.

Table of Contents


In the configuration topic we'll explain how to configure AppSignal, what can be configured in the Ruby gem, what's the minimal configuration needed and how the configuration is loaded.

See our configuration page for the configuration documentation of the AppSignal gem.


The AppSignal Ruby gem integrates with many frameworks like Rails, Sinatra, Padrino, Grape, and more.

See our integrations page for the full list and implementation details.

Custom instrumentation
