Overview

Base class for Sentry log subscribers that extends ActiveSupport::LogSubscriber to provide structured logging capabilities for Rails components.

This class follows Rails’ LogSubscriber pattern and provides common functionality for capturing Rails instrumentation events and logging them through Sentry’s structured logging system.

Creating a custom log subscriber

class MySubscriber < Sentry::Rails::LogSubscriber
  attach_to :my_component

  def my_event(event)
    log_structured_event(
      message: "My event occurred",
      level: :info,
      attributes: {
        duration_ms: event.duration,
        custom_data: event.payload[:custom_data]
      }
    )
  end
end
