# Pretty rough script that sends the information from all your sensors
# to AWS CloudWatch as a single metrics API call. You would run this as
# a cron job every minute.
#
# I'm assuming you have some basic AWS knowledge and know how to configure
# your environment with credentials to send data to AWS.
#
# The most basic IAM policy you need is something like this:
# {
#     "Version": "2012-10-17",
#     "Statement": [
#         {
#             "Sid": "VisualEditor0",
#             "Effect": "Allow",
#             "Action": [
#                 "cloudwatch:PutMetricData"
#             ],
#             "Resource": "*"
#         }
#     ]
# }
