+Redis Enterprise Software version 7.8.2 introduces a preview of the new metrics stream engine that exposes the v2  Prometheus scraping endpoint at `https://<IP>:8070/v2`.
 This new engine exports all time-series metrics to external monitoring tools such as Grafana, DataDog, NewRelic, and Dynatrace using Prometheus.
 
 The new engine enables real-time monitoring, including full monitoring during maintenance operations, providing full visibility into performance during events such as shards' failovers and scaling operations.

 If you are already using the existing scraping endpoint for integration, follow [this guide]({{<relref "/operate/rs/references/metrics/prometheus-metrics-v1-to-v2">}}) to transition and try the new engine. It is possible to scrape both existing and new endpoints simultaneously, allowing advanced dashboard preparation and a smooth transition.
