Sentry's Ruby SDK allows users to report messages, exceptions, and tracing events.

The SDK supports Ruby 2.4+ and the most recent JRuby versions. It also integrates with popular frameworks and libraries via library-specific gems.

On this page, we get you up and running with Sentry's SDK.

Sentry captures data by using an SDK within your application’s runtime.

Add the sentry-ruby and stackprof gems to your Gemfile:

gem "stackprof"
gem "sentry-ruby"

Configuration should happen as early as possible in your application's lifecycle.

require 'sentry-ruby'

Sentry.init do |config|
  config.dsn = ''

  # get breadcrumbs from logs
  config.breadcrumbs_logger = [:sentry_logger, :http_logger]

  # enable tracing
  # we recommend adjusting this value in production
  config.traces_sample_rate = 1.0

  # enable profiling
  # this is relative to traces_sample_rate
  config.profiles_sample_rate = 1.0

This snippet includes an intentional error, so you can test that everything is working as soon as you set it up.

Sentry.capture_message("test message")

Learn more about manually capturing an error or message in our Usage documentation.

To view and resolve the recorded error, log into and open your project. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.
