Fargate Scraper

A CLI tool that scrapes Fargate tasks to find Prometheus targets.

Installation

pip install fargate-scraper

Usage

Give the script the name of the ECS cluster you want to scrape and the location of where it should output the results. It will automatically pick up credentials from its environment. See boto3 for details.

fargate-scraper --cluster-name my-cluster output.json

Then point your prometheus config at that file.

scrape_configs:
  - job_name: prometheus
    metrics_path: "/metrics"
    file_sd_configs:
      - files:
          - output.json
        refresh_interval: 10m

Prometheus will automatically pick up changes to the file.

The script will pick up any Fargate containers that have a METRICS_PORT env var defined.
