# Initialize connection to Cloudwatch
|
|
#
|
|
# ==== Notes
|
|
# options parameter must include values for :aws_access_key_id and
|
|
# :aws_secret_access_key in order to create a connection
|
|
#
|
|
# ==== Examples

|
# elb = CloudWatch.new(
|
|
# :aws_access_key_id => your_aws_access_key_id,

|
# :aws_secret_access_key => your_aws_secret_access_key
|
|
# )
|
|
#
|
|
# ==== Parameters
|
