The old sentry-raven client has entered maintenance mode and was moved to here.

If you're using sentry-raven, we recommend you to migrate to this new SDK. You can find the benefits of migrating and how to do it in our migration guide.

We test from Ruby 2.4 to Ruby 3.2 at the latest patchlevel/teeny version. We also support JRuby 9.0.

If you use self-hosted Sentry, please also make sure its version is above 20.6.0.

gem "sentry-ruby"

and depends on the integrations you want to have, you might also want to install these:

gem "sentry-rails"
gem "sentry-sidekiq"
gem "sentry-delayed_job"
gem "sentry-resque"
gem "sentry-opentelemetry"

You need to use Sentry.init to initialize and configure your SDK:

Sentry.init do |config|
  config.dsn = "MY_DSN"
end

To learn more about available configuration options, please visit the official documentation.

You can activate performance monitoring by enabling traces sampling:

Sentry.init do |config|
  # set a uniform sample rate between 0.0 and 1.0
  config.traces_sample_rate = 0.2
  # you can also use traces_sampler for more fine-grained sampling
  # please click the link below to learn more
end

To learn more about sampling transactions, please visit the official documentation.
