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

Don't already have an account and Sentry project established? Head over to sentry.io, then return to this page.

If you prefer to follow video instructions, see How to Install the Sentry Ruby SDK in 60 Seconds.

Install

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

Add sentry-ruby and sentry-rails to your Gemfile:

gem "sentry-ruby"
gem "sentry-rails"

Configure

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

Initialize the SDK within your config/initializers/sentry.rb:

Sentry.init do |config|
  config.dsn = 'https://examplePublicKey@o0.ingest.sentry.io/0'
  # enable performance monitoring
  config.enable_tracing = true
  # get breadcrumbs from logs
  config.breadcrumbs_logger = [:active_support_logger, :http_logger]
end

Verify

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")

To view and resolve the recorded error, log into sentry.io 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.
