description: Setup Sentry in Ruby apps. Use when asked to add Sentry to Ruby, install sentry-ruby gem, or configure error monitoring for Ruby applications or Rails.

Sentry Ruby Setup

Install and configure Sentry in Ruby projects.

Invoke This Skill When

• User asks to "add Sentry to Ruby" or "install Sentry" in a Ruby app
• User wants error monitoring, logging, or tracing in Ruby
• User mentions "sentry-ruby" gem or Ruby on Rails

Requirements

• Ruby 2.4+ or recent JRuby versions

Install

Add to Gemfile:

gem "sentry-ruby"

# For profiling, also add:
gem "stackprof"

Then run:

bundle install

Configure

Initialize as early as possible:

require "sentry-ruby"

Sentry.init do |config|
  config.dsn = "YOUR_SENTRY_DSN"
  config.send_default_pii = true

  # Breadcrumbs from logs
  config.breadcrumbs_logger = [:sentry_logger, :http_logger]

  # Tracing
  config.traces_sample_rate = 1.0

  # Profiling (requires stackprof gem)
  config.profiles_sample_rate = 1.0

  # Logs
  config.enable_logs = true
end

Rails Integration

For Rails, add to config/initializers/sentry.rb:

Sentry.init do |config|
  config.dsn = ENV["SENTRY_DSN"]
  config.send_default_pii = true
  config.breadcrumbs_logger = [:active_support_logger, :http_logger]
  config.traces_sample_rate = 1.0
  config.profiles_sample_rate = 1.0
  config.enable_logs = true
end

Rails-specific Gems

# Gemfile
gem "sentry-ruby"
gem "sentry-rails"  # Rails integration
gem "sentry-sidekiq"  # If using Sidekiq
gem "sentry-delayed_job"  # If using Delayed Job
gem "sentry-resque"  # If using Resque

Configuration Options

Breadcrumb Loggers

Environment Variables

SENTRY_DSN=https://[email protected]/456
SENTRY_AUTH_TOKEN=sntrys_xxx
SENTRY_ORG=my-org
