Source Installation:
This tool is best run in a virtual environment. You may need to install a virtual environment tool such as python3-venv or python3-virutalenv via your package manager and/or install one via pip by running pip install virtualenv --user.
git clone https://github.com/gregoryjordanm/awsrightsizer.git
cd ./awsrightsizer
python3 -m venv venv or virtualenv -p python3 venv
. ./venv/bin/activate
pip install -r requirements
python rightsizer.py [OPTIONS]
Running Example:
Lets assume for a second that you have already installed the AWS CLI tools for your distribution...
Lets also assume that you have already run the aws configure command and have a profile named "dev" on your system that you have already tested and is functioning :)
To run this tool with your working profile, simply do the following:
rightsizer -p dev
The tool will output a "report_date.csv" file in the directory you ran it in.
Lets now assume that you hate my report name, simply run:
rightsizer -p dev -o your_awesome_new_csv.csv
The tool will now use your_awesome_new_csv.csv is the output file.
If you don't have an AWS profile set up for some reason (it really does make life easier), then you can use the -k, -s. and -r flags to provide the necessary info.
rightsizer -k XXXXXXXXXXXX -s XXXXXXXXXXXXXXXXXXXXXXXX -r us-east-1
If you don't want to have the tool pull 30 days worth of data, or if you don't want the data periods to be 30 minutes, use the -q flag like so:
rightsizer -p dev -q 15,900
This will tell the tool to query 15 days at 15 minute intervals.
To run against just your EC2 assets, just issue the -e flag.
To run against just your RDS assets, just issue the -d flag.
If you are running this via the source, you will need to add python rightsizer.py to your command instead of just rightsizer.
Let me know if you find bugs :)
