Amazon CloudWatch managed Prometheus collectors
Amazon CloudWatch managed Prometheus collectors provides a fully managed, agentless scraper, or collector, that automatically discovers and pulls Prometheus-compatible metrics. With Amazon CloudWatch managed Prometheus collectors, you eliminate the operational overhead of running and scaling your own metric collection infrastructure. The collectors automatically discover targets in your VPC, scrape Prometheus-compatible metrics, and deliver them to CloudWatch. You don't have to manage, install, patch, or maintain agents, collectors or scrapers for Prometheus metrics. Managed collectors automatically scale to provide highly available, reliable metric collection for your AWS infrastructure.
A managed collector creates an Elastic Network Interface (ENI) for each subnet that you specify when you create the scraper. The collector scrapes metrics through these ENIs using OpenTelemetry Protocol (OTLP). It delivers the metrics to your CloudWatch dataset through a VPC endpoint. The scraped data never travels on the public internet. You can query metrics in CloudWatch with PromQL (Prometheus Query Language) for flexible and scalable analytics.
Note
Scraping metrics might incur VPC data transfer charges between the collector and your
targets. To reduce this network transfer cost, configure your Prometheus
/metrics endpoint to compress responses (for example, with gzip).
Compression lowers the volume of data that the collector transfers across the network.
It does not change the number of metrics that CloudWatch ingests.
We charge for Prometheus collectors by the hour, and CloudWatch OpenTelemetry metric ingestion pricing applies. For more information about CloudWatch pricing, see Amazon CloudWatch Pricing
