// The CreateScraper operation creates a scraper to collect metrics. A scraper
// pulls metrics from Prometheus-compatible sources within an Amazon EKS cluster,
// and sends them to your Amazon Managed Service for Prometheus workspace. You can
// configure the scraper to control what metrics are collected, and what
// transformations are applied prior to sending them to your workspace.
//
// If needed, an IAM role will be created for you that gives Amazon Managed
// Service for Prometheus access to the metrics in your cluster. For more
// information, see [Using roles for scraping metrics from EKS]in the Amazon Managed Service for Prometheus User Guide.
//
// You cannot update a scraper. If you want to change the configuration of the
// scraper, create a new scraper and delete the old one.
//
// The scrapeConfiguration parameter contains the base64-encoded version of the
// YAML configuration file.
//
// For more information about collectors, including what metrics are collected,
// and how to configure the scraper, see [Amazon Web Services managed collectors]in the Amazon Managed Service for
// Prometheus User Guide.
