# Instrumentation
ActiveModelSerializers uses the
[ActiveSupport::Notification API](http://guides.rubyonrails.org/active_support_instrumentation.html#subscribing-to-an-event),
which allows for subscribing to events, such as for logging.
## Events
Name:
`render.active_model_serializers`
Payload (example):
```ruby
{
serializer: PostSerializer,
adapter: ActiveModelSerializers::Adapter::Attributes
}
```
Subscribing:
```ruby
ActiveSupport::Notifications.subscribe 'render.active_model_serializers' do |name, started, finished, unique_id, data|
# whatever
end
ActiveSupport::Notifications.subscribe 'render.active_model_serializers' do |*args|
event = ActiveSupport::Notifications::Event.new(*args)
# event.payload
# whatever
end
```
## [LogSubscriber](http://api.rubyonrails.org/classes/ActiveSupport/LogSubscriber.html)
ActiveModelSerializers includes an `ActiveModelSerializers::LogSubscriber` that attaches to
`render.active_model_serializers`.
