CloudFormation example to demonstrate automating the process of sending logs and system metrics to CloudWatch

Example: CloudFormation + CloudWatch Logs + CloudWatch Custom metrics

Spins up an EC2 instance via CloudFormation and demonstrates how to do the following during the bootstrap process:

Configure Python daemon that automatically pushes various log files to CloudWatch
Configure cron script to push custom metrics (memory, swap, etc.) to CloudWatch

Prerequisites:

AWS account
AWS CLI
IAM user with sufficient privileges + access key
Run aws configure to set the desired region, access key, secret access key
An existing VPC, public subnet, key pair, and security group that allows SSH access in the desired AWS region

To Run:

Edit create-stack.sh as necessary:
KeyName the name of the key pair in the desired AWS region
ExistingSecurityGroupId is the ID of an existing security group (e.g. sg-xxxxxxxx)
See cloudformation.template for complete list of parameters
Run ./create-stack.sh to provison and configure all resources.

Cleanup:

When finished, run ./delete-stack.sh to tear down all resources.

Notes:

The current region-to-AMI-mapping defined in cloudformation.template only specifies an AMI for us-west-2 (Oregon region)
The default AMI is CentOS7
It should be trivial to modify this mapping to add support for additional regions if necessary
