# Prometheus metrics v2 ```json metadata { "title": "Prometheus metrics v2", "description": "V2 metrics available to Prometheus as of Redis Software version 7.8.2.", "categories": ["docs","integrate","rs"], "group": "observability", "tableOfContents": {"sections":[]} , "codeExamples": [] } ``` You can [integrate Redis Software with Prometheus and Grafana](https://redis.io/docs/latest/integrate/prometheus-with-redis-enterprise/) to create dashboards for important metrics. The v2 metrics in the following tables are available as of Redis Software version 7.8.0. For help transitioning from v1 metrics to v2 PromQL, see [Prometheus v1 metrics and equivalent v2 PromQL](https://redis.io/docs/latest/integrate/prometheus-with-redis-enterprise/prometheus-metrics-v1-to-v2). The v2 scraping endpoint also exposes metrics for `node_exporter` version 1.8.1.
