0.16.0-alpha

  • Hugh rewrite: Decouple scraping and serving metrics. Thanks so much daviddetorres!
  • BREAKING CHANGE Decoupled scraping and set scraping interval to 5 minutes.
The flag 'decoupled-scraping' makes the exporter to scrape Cloudwatch metrics in background in fixed intervals, in stead of each time that the '/metrics' endpoint is fetched. This protects from the abuse of API requests that can cause extra billing in AWS account. This flag is activated by default.

If the flag 'decoupled-scraping' is activated, the flag 'scraping-interval' defines the seconds between scrapes. Its default value is 300.
