Gem Version Build Status Coverage Status Gem SemVer

The official Ruby-language client and integration layer for the Sentry error reporting API.

Getting Started

Install

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

gem "opentelemetry-sdk"
gem "opentelemetry-instrumentation-all"

Configuration

Initialize Sentry for tracing and set the instrumenter to :otel.

# config/initializers/sentry.rb

Sentry.init do |config|
  config.dsn = "MY_DSN"
  config.traces_sample_rate = 1.0
  config.instrumenter = :otel
end

This will disable all Sentry instrumentation and rely on the chosen OpenTelemetry tracers for creating spans.

Next, configure OpenTelemetry as per your needs and hook in the Sentry span processor and propagator.

# config/initializers/otel.rb

OpenTelemetry::SDK.configure do |c|
  c.use_all
  c.add_span_processor(Sentry::OpenTelemetry::SpanProcessor.instance)
end

OpenTelemetry.propagation = Sentry::OpenTelemetry::Propagator.new
