The AppSignal gem can instrument events emitted by the ViewComponent Ruby gem. In order for AppSignal to be able to instrument these events, ViewComponent must be configured to emit these events. For example, in your config/application.rb file: 
# config/application.rb
module MyRailsApp
  class Application < Rails::Application
    # add the following lines
    config.view_component.instrumentation_enabled = true
    config.view_component.use_deprecated_instrumentation_name = false
  end
end
Events for ViewComponent components rendered by your application will appear in the event timeline of your application’s performance actions.
