Sentry's Ruby SDK allows users to report messages, exceptions, and tracing events.
The SDK supports Ruby 2.4+ and the most recent JRuby versions. It also integrates with popular frameworks and libraries via library-specific gems.
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.
If you don't already have an account and Sentry project established, head over to sentry.io, then return to this page.
Sentry captures data by using an SDK within your application’s runtime.
sentry-ruby gem to your
Configuration should happen as early as possible in your application's lifecycle.
use Sentry::Rack::CaptureException and
use Sentry::Rack::Tracing to your
config.ru or other rackup file:
require 'sentry-ruby' Sentry.init do |config| config.dsn = 'https://examplePublicKey@o0.ingest.sentry.io/0' # To activate performance monitoring, set one of these options. # We recommend adjusting the value in production: config.traces_sample_rate = 0.5 # or config.traces_sampler = lambda do |context| true end end use Sentry::Rack::Tracing # this needs to be placed first use Sentry::Rack::CaptureException
This snippet includes an intentional error, so you can test that everything is working as soon as you set it up:
Or, by manually generating an event:
begin 1 / 0 rescue ZeroDivisionError => exception Sentry.capture_exception(exception) end
Learn more about manually capturing an error or message, in our Usage documentation.
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.
