# 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

|
* Instances
|
|
* KMS Keys
|
|
* Lambda Functions
|

|
* NAT Gateways
|
|
* Network ACLs
|
|
* IAM Policies
|
|
* RDS Instances
|
|
* IAM Roles
|
|
* S3 Buckets
|
|
* SAML Providers

## 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...
