Redis Enterprise - PrometheusRedis Enterprise - Prometheus
Monitor Redis Enterprise with the official Redis Prometheus exporter.
Extension- Product information
- Release notes
Overview
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 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 enables you to:
- Monitor Redis with a comprehensive dashboard and Dynatrace entities
- Detect anomalies and alert on them
Compatibility Requirements:
- Redis Enterprise
Use cases
This extension enables insights into the overall health of the Redis cluster and components.
This extension scrapes many of the metrics listed at: Redis Prometheus Metrics
Get started
Simply activate the extension in your environment using the in-product Hub, provide the necessary device configuration and you’re all set up.

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 Dynatrace, create a new Monitoring Configuration and select 'Monitor Remotely without OneAgent" near the bottom of the Monitoring Source Screen.
- Select the Dynatrace ActiveGate group to run this extension from
- Add the Redis Prometheus endpoint e.g.
https://redis.cluster:8070. With auth if required. - Add a basic description and select 'Activate'
[Optional] Redis Configuration
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.
Compatibility information
Redis Enterprise. Open-source Redis does not include the required metrics_exporter.
