Module: RailsErrorDashboard::Integrations::OTel

Defined in:
lib/rails_error_dashboard/integrations/o_tel.rb

Overview

Detection shim for the OpenTelemetry SDK. The LLM-observability feature registers a SpanProcessor against ‘OpenTelemetry.tracer_provider` when the host app already runs OTel — for ruby_llm and thoughtbot users this is the zero-config path. When OTel is absent, we silently skip the SpanProcessor (the Faraday middleware path still works).

‘opentelemetry-sdk` is an OPTIONAL dependency. This module must never raise, never require the gem itself, and never assume the host has it.

Class Method Details

.available? ⇒ Boolean

Returns true when the OpenTelemetry SDK is loaded and the SpanProcessor base class is reachable (Task 2.2 subclasses it). Memoized — host apps don’t dynamically load gems mid-process. Rescues any unexpected error to a hard false: a broken partial install must never block a request in the host app.

Returns:

  • (Boolean)

def available?
  return @available unless @available.nil?
  @available = detect
rescue StandardError
  @available = false
end

.reset! ⇒ Object

Test hook — clears the memoized result so specs can flip OpenTelemetry constants in/out between examples.
