# This class is the starting point for working with Amazon CloudWatch.

#

# To use Amazon CloudWatch you must first

# [sign up here](http://aws.amazon.com/cloudwatch/).

#

# For more information about Amazon CloudWatch:

#

# * [Amazon CloudWatch](http://aws.amazon.com/cloudwatch/)

# * [Amazon CloudWatch Documentation](http://aws.amazon.com/documentation/cloudwatch/)

#

# # Credentials

#

# You can setup default credentials for all AWS services via

# AWS.config:

#

# AWS.config(

# :access_key_id => 'YOUR_ACCESS_KEY_ID',

# :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')

#

# Or you can set them directly on the AWS::CloudWatch interface:

#

# cw = AWS::CloudWatch.new(

# :access_key_id => 'YOUR_ACCESS_KEY_ID',

# :secret_access_key => 'YOUR_SECRET_ACCESS_KEY')

#

# # Using the Client

#

# AWS::CloudWatch does not provide higher level abstractions for CloudWatch at

# this time. You can still access all of the API methods using

# {AWS::CloudWatch::Client}. Here is how you access the client and make

# a simple request:

#

# cw = AWS::CloudWatch.new

#

# resp = cw.client.describe_alarms

# resp[:metric_alarms].each do |alarm|

# puts alarm[:alarm_name]

# end

#

# See {Client} for documentation on all of the supported operations.

#

# @!attribute [r] client

# @return [Client] the low-level CloudWatch client object
