Send high-availability data to Amazon Managed Service for Prometheus with AWS Distro for Open Telemetry

AWS Distro for Open Telemetry (ADOT) is a secure and production-ready distribution of the OpenTelemetry project. ADOT provides you with source APIs, libraries, and agents, so you can collect distributed traces and metrics for application monitoring. For information about ADOT, see About AWS Distro for Open Telemetry.

To set up ADOT with a high availability configuration, you must configure an ADOT collector container image and apply the external labels cluster and __replica__ to the AWS Prometheus remote write exporter. This exporter sends your scraped metrics to your Amazon Managed Service for Prometheus workspace via the remote_write endpoint. When you set these labels on the remote write exporter, you prevent duplicate metrics from being kept while redundant replicas run.
