Integrating Amazon Cloudwatch metrics into Prometheus is essential for centralizing observability data, as Cloudwatch is primarily used for AWS infrastructure logs and metrics, but not for application metrics. This separation can complicate understanding the overall system state, leading to the need for a unified data repository. The Prometheus Cloudwatch Exporter serves as a bridge, enabling the ingestion of Cloudwatch metrics into Prometheus by running an exporter on an Amazon EC2 instance, which scrapes metrics and makes them available for Prometheus to query. The process involves installing and configuring the exporter, creating a configuration file to specify desired metrics, and adjusting the Prometheus configuration to scrape data from the exporter. While this setup can be complex, using a unified observability platform like Coralogix may offer a more powerful and scalable solution for managing telemetry data.
