Prometheus Remote Write destination plugin

Prometheus Remote Write is a feature of Prometheus, an open-source monitoring system, that allows you to send metrics data from Prometheus to another system or storage backend. It enables you to export data from Prometheus to a remote system, such as an object storage service or a database, for long-term storage and analysis.

Prometheus Remote Write works by sending metrics data in a standardized format over HTTP to the configured remote endpoint. This allows you to use different storage backends and analysis tools with Prometheus, and to centralize your monitoring data in a single location. It allows you to export data from Calyptia Core to a variety of storage and analysis systems for long-term storage and analysis.
