# Metrics stream engine preview for monitoring v2 A preview of the new metrics stream engine is available as of [Redis Enterprise Software version 7.8.2](https://redis.io/docs/latest/operate/rs/release-notes/rs-7-8-releases). The new metrics stream engine: - Exposes the v2 Prometheus scraping endpoint at `https://:8070/v2`. - Exports all time-series metrics to external monitoring tools such as Grafana, DataDog, NewRelic, and Dynatrace using Prometheus. - Enables real-time monitoring, including full monitoring during maintenance operations, which provides full visibility into performance during events such as shards' failovers and scaling operations. ## Integrate with external monitoring tools To integrate Redis Enterprise metrics into your monitoring environment, see the integration guides for [Prometheus and Grafana](https://redis.io/docs/latest/operate/rs/monitoring/prometheus_and_grafana). Filter [Libraries and tools](https://redis.io/docs/latest/integrate) by "observability" for additional tools and guides. ## Prometheus metrics v2 For a list of all available v2 metrics, see [Prometheus metrics v2](https://redis.io/docs/latest/operate/rs/references/metrics/prometheus-metrics-v2). The v2 scraping endpoint also exposes metrics for `node_exporter` version 1.8.1. For more information, see the [Prometheus node_exporter GitHub repository](https://github.com/prometheus/node_exporter). ## Transition from Prometheus v1 to Prometheus v2 If you are already using the existing scraping endpoint for integration, follow [this guide](https://redis.io/docs/latest/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.
