I have been playing around with different caching strategies on Heroku and have add their memcached add-on with an aim to add action caching to my app.
When I view Rails.cache.stats on my current app however (with memcached installed and using the dalli gem) I get current and total_items at 0 after performing the actions that should be cached.
At the top of the controller with the action I want to cache I have:
caches_action :show
Also, I modified my environment config (for the one running on Heroku) to have
config.cache_store = :dalli_store
Is there some other stats I can look at to see if it is working or have I done something wrong?

Heroku doesn't provide HTTP caching by default. In order to take advantage of HTTP caching, you'll need to configure your application to set the appropriate HTTP cache control headers and use a content delivery network (CDN) or other external caching service.
Query caching is a Rails feature that caches the result set returned by each query. If Rails encounters the same query again for that request, it will use the cached result set as opposed to running the query against the database again.
You need to enable caching as well as configuring a cache store:
config.action_controller.perform_caching = true
