Redis integration for Grafana Cloud
Redis is an in-memory data structure store frequently used as a key-value data store, cache, and message broker. The Redis integration enables the agent to send metrics to Grafana Cloud.
This integration includes three useful alerts and a pre-built dashboard to help monitor and visualize Redis metrics.
Install Redis integration for Grafana Cloud
- In your Grafana Cloud instance, click Integrations and Connections (lightning bolt icon).
- Navigate to the Redis tile and review the prerequisites. Then click Install integration.
- Once the integration is installed, follow the steps on the Configuration Details page to setup Grafana Agent and start sending Redis metrics to your Grafana Cloud instance.
Post-install configuration for the Redis integration
It is recommended to configure a separate user for the Agent, and give it only the strictly mandatory security privileges necessary for monitoring your node, as per the official documentation.
Making sure to change the redis_addr to the address of the Redis server you want to monitor in the agent config:
integrations:
redis_exporter:
enabled: true
redis_addr: 'redis:6379'
For a full description of configuration options, including guidance on monitoring more than one Redis server, see redis_exporter_config in the Agent documentation.
Dashboards
The Redis integration installs the following dashboards in your Grafana Cloud instance to help monitor your metrics.
