Redis Enterprise - Prometheus extension
- Latest Dynatrace
- Extension
- Published Oct 27, 2025
Monitor Redis Enterprise with the official Redis Prometheus exporter.
Get started
Overview
Monitor Redis Enterprise with the official Redis Prometheus exporter.
This extensions provides the ability to remotely monitor your Redis Enterprise Clusters, Databases, Nodes, Proxies, Replicas and Shards. Every minute, this extension polls metrics through the official Redis Prometheus exporter to ingest data about how each resource is performing.
This page is intended for users, who:
- Would like to monitor the health state and performance of their Redis Enterprise resources.
- Look for analysis support for Ops, IT and Database admins
This extension enables you to:
- Monitor Redis with a comprehensive dashboard and Dynatrace entities
- Detect anomalies and alert on them
Use cases
- Enable insights into the overall health of the Redis cluster and components.
This extension scrapes many of the metrics listed at Redis Prometheus Metrics.
Requirements
Redis Enterprise is required.
Compatibility information
Open Source Redis does not include the metrics exporter.
V2 metrics are available on:
- All new Redis Cloud Subscriptions
- Redis Enterprise Software 7.8 +
Activation and setup
Simply activate the extension in your environment using the in-product Hub, provide the necessary device configuration and you’re all set up.
Read more in the Dynatrace Prometheus Extension Documentation.
In Dynatrace, create a new Monitoring Configuration:
- Add the Redis Prometheus endpoint. With auth if required.
- v1 metrics are available on the root endpoint e.g.
https://redis.cluster:8070 - v2 metrics are available on the /v2 endpoint e.g.
https://redis.cluster:8070/v2 - Select the required featuresets which contain the metrics to collect.
- Add a basic description and select Activate.
This extension supports both Redis Prometheus exports v1 and v2, but monitoring configuration needs to specify the right endpoints.
- Prometheus metrics v2
- Default - feature sets do not have a specific prefix. Just the resource type itself.
- Prometheus metrics v1
- To monitor v1 metrics, instead enable featuresets which are prefixed with
v1-
- To monitor v1 metrics, instead enable featuresets which are prefixed with
[Optional] Version 1 Redis activation
The Database name - label bdb_name is not enabled by default. Without this, Dynatrace will just use the database ID in dimensions and entity definitions.
To enable it for all databases on a cluster you have to issue the following commands:
ccs-cli hset cluster_settings metrics_exporter_expose_bdb_name enabledsupervisorctl restart metrics_exporter
The new labels will then be added to the Prometheus metrics once this setting is changed and the metrics_exporter process is restarted.
Details
This extension uses the Redis Enterprise Prometheus Endpoint to scrape and ingest metrics. This Redis metrics_exporter component is enabled by default and listens on Port 8070.
In this context Dynatrace is the Prometheus Server. Prometheus is not required.
Licensing and cost
There is no charge for obtaining the extension, only for the data that the extension ingests. The details of license consumption will depend on which licensing model you are using. This will either be Dynatrace classic licensing or the Dynatrace Platform Subscription (DPS) model.
Metrics
License consumption is based on the number of metric data points ingested. The following formula will provide approximate annual data points ingested assuming all feature sets are enabled.
((( 8 * number of clusters )+ ( 47 * number of databases )+ ( 26 * number of nodes )+ ( 24 * number of replicas )+ ( 108 * number of shards )+ ( 11 * number of proxies )+ 2)) * 60 minutes * 24 hours * 365 days data points per year
Classic licensing
In the Dynatrace classic licensing model, metric ingestion will consume Davis Data Units (DDUs) at the rate of .001 DDUs per metric data point. Multiply the above formula for annual data points by .001 to estimate annual DDU usage.
Feature sets
When activating your extension using monitoring configuration, you can limit monitoring to one of the feature sets. To work properly the extension has to collect at least one metric after the activation.
In highly segmented networks, feature sets can reflect the segments of your environment. Then, when you create a monitoring configuration, you can select a feature set and a corresponding ActiveGate group that can connect to this particular segment.
All metrics that aren't categorized into any feature set are considered to be the default and are always reported.
A metric inherits the feature set of a subgroup, which in turn inherits the feature set of a group. Also, the feature set defined on the metric level overrides the feature set defined on the subgroup level, which in turn overrides the feature set defined on the group level.
