  "summary": "This article describes how to configure a Prometheus operator custom resource to allow it to export metrics from Redis Enterprise for Kubernetes.",
  "content": "\nTo collect  metrics data from your databases and Redis Enterprise cluster (REC), you can connect your [Prometheus](https://prometheus.io/) server to an endpoint exposed on your REC. Redis Enterprise for Kubernetes creates a dedicated service to expose the `prometheus` port (8070) for data collection. A custom resource called `ServiceMonitor` allows the [Prometheus operator](https://github.com/prometheus-operator/prometheus-operator/tree/main/Documentation) to connect to this port and collect data from Redis Enterprise.\n\nTo expose database tags as metric labels so you can filter and group metrics by attributes such as environment or team, see [Enrich database metrics with tags](https://redis.io/docs/latest/operate/kubernetes/re-databases/enrich-metrics-with-tags).\n\n## Prerequisites\n\nBefore connecting Redis Enterprise to Prometheus on your Kubernetes cluster, make sure you've done the following:\n\n- [Deploy Redis Enterprise for Kubernetes](https://redis.io/docs/latest/operate/kubernetes/deployment/quick-start) (version 6.2.10-4 or newer)\n- [Deploy the Prometheus operator](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/getting-started/introduction.md) (version 0.19.0 or newer)\n- [Create a Redis Enterprise cluster](https://redis.io/docs/latest/operate/kubernetes/deployment/quick-start#create-a-redis-enterprise-cluster-rec)\n\n## Create a `ServiceMonitor` custom resource\n\nBelow is an example `ServiceMonitor` custom resource file. By specifying the service label (`app: redis.io/service=prom-metrics`) in the `selector.matchLabels` section, you can point the Prometheus operator to the correct Redis Enterprise service (`\u003crec_name\u003e-prom`).\n\nYou'll need to configure the following fields to connect Prometheus to Redis Enterprise:\n\n| Section | Field | Value |\n|---|---|---|\n| `spec.endpoints` | `port` | Name of exposed port (`prometheus`) |\n| `spec.namespaceSelector` | `matchNames` | Namespace for your REC |\n| `spec.selector` | `matchLabels` | REC service label (`app: redis.io/service=prom-metrics`) |\n\nApply the file in the same namespace as your Redis Enterprise cluster (REC).\n\n\u003e [!NOTE]\n\u003e If Redis Enterprise and Prometheus are deployed in different namespaces, you'll also need to add the [`serviceMonitorNamespaceSelector`](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/api-reference/api.md) field to your Prometheus resource. See the [Prometheus operator documentation](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/user-guides/running-exporters.md) for more details on cross-namespace `ServiceMonitor` configuration.\n\n\n```YAML\napiVersion: monitoring.coreos.com/v1\nkind: ServiceMonitor\nmetadata:\n  name: redis-enterprise\nspec:\n  endpoints:\n  - interval: 15s\n    port: prometheus\n    scheme: https\n    tlsConfig:\n      insecureSkipVerify: true\n  namespaceSelector:\n    matchNames:\n    - \u003cyour_REC_namespace\u003e\n  selector:\n    matchLabels:\n      redis.io/service: prom-metrics\n```\n\nFor more info about configuring the `ServiceMonitor` resource, see the [`ServiceMonitorSpec` API documentation](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/api-reference/api.md#monitoring.coreos.com/v1.ServiceMonitorSpec).\n\n## More info\n\n- github.com/prometheus-operator\n  - [Getting started](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/getting-started/introduction.md)\n  - [Running exporters](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/user-guides/running-exporters.md)\n  - [Troubleshooting ServiceMonitor changes](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/platform/troubleshooting.md#troubleshooting-servicemonitor-changes)\n- redis.io/docs\n  - [Metrics in Prometheus](https://redis.io/docs/latest/integrate/prometheus-with-redis-enterprise/prometheus-metrics-definitions)\n  - [Monitoring and metrics](https://redis.io/docs/latest/operate/rs/monitoring)\n",
