Transition from Prometheus v1 to Prometheus v2
Transition from v1 metrics to v2 PromQL equivalents.
You can integrate Redis Enterprise Software with Prometheus and Grafana to create dashboards for important metrics.
As of Redis Enterprise Software version 7.8.2, PromQL (Prometheus Query Language) metrics are available, and v1 metrics are deprecated. You can use the following tables to transition from v1 metrics to equivalent v2 PromQL. For a list of all available v2 PromQL metrics, see Prometheus metrics v2.
