resource-counter

This command line tool counts the number of resources in different categories across Amazon regions.

This is a simple Python app that will count resources across different regions and display them on the command line. It first shows the dictionary of the results for the monitored services on a per-region basis, then it shows totals across all regions in a friendlier format. It tries to use the most-efficient query mechanism for each resource in order to manage the impact of API activity. I wrote this to help me scope out assessments and know where resources are in a target account.

The development plan is to upgrade the output (probably to CSV file) and to continue to add services. If you have a specific service you want to see added just add a request in the comments.

The current list incluides:

• Application and Network Load Balancers
• Autoscale Groups
• Classic Load Balancers
• CloudTrail Trails
• Cloudwatch Rules
• Config Rules
• Dynamo Tables
• Elastic IP Addresses
• Glacier Vaults
• IAM Groups
• Images
• Instances
• KMS Keys
• Lambda Functions
• Launch Configurations
• NAT Gateways
• Network ACLs
• IAM Policies
• RDS Instances
• IAM Roles
• S3 Buckets
• SAML Providers
• SNS Topics
• Security Groups
• Snapshots
• Subnets
• IAM Users
• VPC Endpoints
• VPC Peering Connection
• VPCs
• Volumes

Usage:

To install just copy it where you want it and instally the requirements:

pip install -r ./requirements.txt

This was written in Python 3.6.

To run:

python count_resources.py 

By default, it will use whatever AWS credentials are alerady configued on the system. You can also specify an access key/secret at runtime and this is not stored. It only neeeds read permissions for the listed services- I use the ReadOnlyAccess managed policy, but you should also be able to use the SecurityAudit policy.

Usage: count_resources.py [OPTIONS]

Options:
  --access TEXT   AWS Access Key. Otherwise will use the standard credentials
              path for the AWS CLI.
  --secret TEXT   AWS Secret Key
  --profile TEXT  If you have multiple credential profiles, use this option to
              specify one.
  --help          Show this message and exit.

Sample Output:

Establishing AWS session using the profile- dev Current account ID: xxxxxxxxxx Counting resources across regions. This will take a few minutes...
