Install

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

Add the sentry-ruby gem to your Gemfile:

Gemfile
Copied
gem "sentry-ruby"

Configure

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

Copied
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
