AWS Limits Exporter

This is a small Go server that provides a Prometheus metrics endpoint that exposes AWS usage and limits as reported by the AWS Trusted Advisor API.

Usage

There are Docker images ready for use:

# Start exporter container
$ docker run -it --rm -p 8080:8080 -e AWS_ACCESS_KEY=<KEY> -e AWS_SECRET_ACCESS_KEY=<SECRET> \
      danielfm/aws-limits-exporter:latest -logtostderr

# Scrape metrics
$ curl http://localhost:8080/metrics

AWS Credentials

For this to work, it must have access to AWS credentials in ~/.aws/credentials, or via AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables.

The following IAM policy describes which actions the user must be able to perform in order for this server to work:

        {
