Send EC2 instance memory usage stats to CloudWatch using boto and IAM Roles
#!/usr/bin/env python
'''
Send memory usage metrics to Amazon CloudWatch
This is intended to run on an Amazon EC2 instance and requires an IAM
role allowing to write CloudWatch metrics. Alternatively, you can create
a boto credentials file and rely on it instead.
Original idea based on https://github.com/colinbjohnson/aws-missing-tools

Get the subnet and VPC id of a running EC2 instance

First get the Interface mac address, then use that to run the full command

INTERFACE=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/)
SUBNET_ID=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/${INTERFACE}/subnet-id)
VPC_ID=$(curl --silent http://169.254.169.254/latest/meta-data/network/interfaces/macs/${INTERFACE}/vpc-id)

echo SUBNET_ID
