Get metrics from Redis’s Sentinel service in real time to:
- Visualize and monitor sentinels states
- Be notified about failovers
Setup
The Redis Sentinel check is not included in the Datadog Agent package, so you need to install it.
Installation
For Agent v7.21+ / v6.21+, follow the instructions below to install the Redis Sentinel check on your host. See Use Community Integrations to install with the Docker Agent or earlier versions of the Agent.
Run the following command to install the Agent integration:
datadog-agent integration install -t datadog-redis_sentinel==<INTEGRATION_VERSION>
Configure your integration similar to core integrations.
Configuration
Edit the redis_sentinel.d/conf.yaml file in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your Redis Sentinel metrics.
See the sample upsc.d/conf.yaml for all available configuration options.
Restart the Agent
Validation
Run the Agent’s status subcommand and look for redis_sentinel under the Checks section.
