How to Set Up Bugsly in Ruby on Rails

Production Ruby on Rails apps encounter errors you'd never see in development. Error monitoring surfaces these issues with the context you need to fix them fast.

Prerequisites

Before you begin, make sure you have a Bugsly account and a Ruby on Rails project ready to instrument. You'll need your project DSN from the Bugsly dashboard — find it under Settings > Projects > Client Keys.

Step-by-Step Integration

1. Add the Bugsly package to your Ruby on Rails project:

bundle add bugsly-ruby

1. Configure the SDK at your application's entry point:

# config/initializers/bugsly.rb
Bugsly.init do |config|
  config.dsn = "YOUR_BUGSLY_DSN"
  config.traces_sample_rate = 1.0
  config.breadcrumbs_logger = [:active_support_logger]
end

1. Deploy your changes and verify events appear in the Bugsly dashboard.

Fine-Tuning Your Setup

After the basic integration works, consider these adjustments for Ruby on Rails:

• Sampling rate: Adjust tracesSampleRate based on your traffic volume. High-traffic apps should sample at 0.1–0.3 to control costs.
• Environment tags: Tag events with production, staging, or development to filter noise.
• Release tracking: Pass your version string so Bugsly can track regressions across deployments.
• Custom context: Attach user IDs, request metadata, or business-specific data to events for richer debugging.

Bugsly's error monitoring for Ruby on Rails runs with minimal overhead. The SDK is designed to be lightweight, batching events and sending them asynchronously so your application performance stays unaffected.

Next Steps

Once error monitoring is live, set up issue ownership rules to automatically assign errors to the right team. Configure integration with your project management tool to create tickets from Bugsly issues. Enable weekly reports to track your team's progress on reducing error rates across releases.
