Metrics Stream Engine - Redis

A preview of the new metrics stream engine is available as of Redis Enterprise Software version 7.8.2.

The new metrics stream engine:

Exposes the v2 Prometheus scraping endpoint at https://<IP>: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]({{< relref "/operate/rs/7.8/monitoring/prometheus_and_grafana" >}}).

Filter [Libraries and tools]({{<relref "/integrate">}}) by "observability" for additional tools and guides.

Prometheus metrics v2

For a list of all available v2 metrics, see [Prometheus metrics v2]({{<relref "/operate/rs/7.8/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.

Transition from Prometheus v1 to Prometheus v2

If you are already using the existing scraping endpoint for integration, do the following to transition from v1 metrics to v2 metrics:

Change the metrics_path in your Prometheus configuration file from / to /v2 to use the new scraping endpoint.

Here's an example of the updated scraping configuration in prometheus.yml:

yaml

scrape_configs:
  # Scrape Redis Enterprise
  - job_name: redis-enterprise
    scrape_interval: 30s
    scrape_timeout: 30s
    metrics_path: /v2
    scheme: https
    tls_config:
      insecure_skip_verify: true
    static_configs:
      - targets: ["<cluster_name>:8070"]

Use the metrics tables in [this guide]({{<relref "/operate/rs/7.8/references/metrics/prometheus-metrics-v1-to-v2">}}) to transition from v1 metrics to equivalent v2 PromQL.

It is possible to scrape both existing and new endpoints simultaneously, allowing advanced dashboard preparation and a smooth transition.
