Connect your Rails project to GlitchTip

Add the sentry Rails SDK to your Gemfile:

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

Then run bundle install.

Create config/initializers/sentry.rb:

Sentry.init do |config|
  config.dsn = "YOUR_DSN"
  config.traces_sample_rate = 0.01 # 1% of transactions
  config.breadcrumbs_logger = [:active_support_logger, :http_logger]
end

All uncaught exceptions in controllers are automatically reported.

Verify your setup with a test route:

get "/debug-glitchtip" => proc { raise "Test GlitchTip error!" }

Tips

• Set traces_sample_rate to a low value in production. Each HTTP request is a transaction — even 1% gives useful performance data without excessive storage.
• The SDK automatically adds breadcrumbs for Active Support events and HTTP requests.
