check-aws-reserved-instances

This script shows summary about using "Reserved" and "On-demand" ec2 instances. Namely:

• Which "On-demand" instances haven't got a "Reserved" instance;
• Which "Reserved" instances are unused;
• And which "Reserved" instances are expiring soon.

The script is heavily based on Scott Bigelow's work: https://github.com/epheph/ec2-check-reserved-instances

Requirements

• Python 2.6+
• argparse (required when using Python 2.6)
• boto3

How to work with it

For the script needs your AWS Security Credentials. You can specify them in the Boto config (~/.boto or /etc/boto.cfg) or using script command line arguments or by exporting in an environment variables (AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY).

Example:

host# export AWS_ACCESS_KEY_ID=ABCDE
host# export AWS_SECRET_ACCESS_KEY=5ji7haengeeFoh8eziebeu
host# ./check-reserved-instances --region us-west-1 -w 60
Unused reserved instances:
	(2)	Linux/UNIX m1.small	us-west-1c
	(3)	Linux/UNIX m1.large	us-west-1c

Soon expiring (less than 60d) reserved instances:
	93bbbca2-d072-4dcc-bb7e-7c137ad565f7	Linux/UNIX m1.small	us-west-1c	2014-04-15
	bbcd9749-4bf0-440a-bf53-3641e3732b73	Linux/UNIX m1.small	us-west-1c	2014-04-03

On-demand instances, which haven't got a reserved instance:
	(1)	Linux/UNIX m3.medium	us-west-1c
	(3)	Linux/UNIX m1.large	us-west-1b
	(1)	Linux/UNIX m1.medium	us-west-1b

Running on-demand instances:   27
Reserved instances:            22
