Ruby

On this page, we get you up and running with Sentry's SDK, so that it will automatically report errors and exceptions in your application.

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

Install

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

gem "sentry-ruby"

Configure

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

require 'sentry-ruby'

Sentry.init do |config|
  config.dsn = 'https://examplePublicKey@o0.ingest.sentry.io/0'
  config.breadcrumbs_logger = [:sentry_logger, :http_logger]

  # To activate performance monitoring, set one of these options.
  # We recommend adjusting the value in production:
  config.traces_sample_rate = 1.0
  # or
  config.traces_sampler = lambda do |context|
    0.5
  end
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.
