There is an Nginx server acting as a proxy in front of Riak CS.

There is not a problem listing all the users with Fog::RiakCS::Provisioning.new 
but usage (Fog::RiakCS::Usage.new) with the same configuration has an Access 
Denied error.

Hi Michael,

You have port 80 listed in configuration, default port is 8080.

I have a small script that I am trying to set up that can read usage stats in 
Ruby Fog. The script is largely pieced together from examples from the Basho 
site and Fog github project. The script is below.



The issue I am running into is the following error:

<Error>

                <Code>AccessDenied</Code>

                <Message>Access Denied</Message>

                <RequestId></RequestId>

</Error>



The list user (users = provisioning.list_users.body) works. The key and secret 
is for the admin user.



Why would I get an Access Denied for the admin user?



--------------RUBY CODE-------------

require 'rubygems'

require 'fog'



def show_usage(usage, key)

        utilization = usage.get_usage(  "/usage/#{key}",

                        :types          => [:access, :storage]

                        )



        objects = 0

        bytes = 0



        # Retrieve Storage information

        utilization.body['Storage']['Samples'][0].each do |k,v|

                # Sum the # of objects and bytes stored from each user bucket 
for per tenant totals

                if v.is_a?(Hash) # To ignore StartTime & EndTime

                        objects += v['Objects']

                        bytes   += v['Bytes']

                end

        end



        puts "  showUsage objects:       #{objects}"

        puts "  showUsage bytes:         #{bytes}"

end



configuration = {

  :port                     => 80,

}



Excon.defaults[:ssl_verify_peer] = false



# Requests for User Provision and Usage information

provisioning = Fog::RiakCS::Provisioning.new(configuration)

usage        = Fog::RiakCS::Usage.new(configuration)





users = provisioning.list_users.body



# The following block of code displays all available information for every user

users.each do | user |
