use with the name of the instrumentation:
::SDK.configure do |c| c.use 'OpenTelemetry::Instrumentation::Rails' c.use 'OpenTelemetry::Instrumentation::ActionView' end

ActionView instrumentation uses ActiveSupport notifications and in the case when a subscriber raises in start method an unclosed span would break successive spans ends. Example:
class CrashingEndSubscriber def start(name, id, payload) raise 'boom' end def finish(name, id, payload) end end ::ActiveSupport::Notifications.subscribe('render_template.action_view', CrashingStartSubscriber.new)
