Memcache Stats Not Outputting with Rails.cache.sta

Question

Good evening,

I'm trying to do some testing of the caching on my Rails app on Heroku, but Memcachier does not appear to be playing nicely...

I can pull values out of the cache no problem, but the stats doesn't give me any love...

=> "42:Quotes:2012-04-16"
irb(main):016:0> Rails.cache.exist?(str)
=> true
irb(main):017:0> Rails.cache.read(str)
=> {"VCE.TO"=>24.76, "XIU.TO"=>17.19, "EWC"=>27.44}
irb(main):018:0> Rails.cache.stats
=> {"mc1.ec2.memcachier.com:11211"=>{}}    

Should there not be some data in the stats if I can pull information out of the cache? I have the following in my gemfile:

gem 'dalli'
gem 'memcachier'

And the following in production.rb:

config.action_controller.perform_caching = true
config.cache_store = :dalli_store

Any help would be appreciated - I can post more detail as required!
