Host

To configure this check for an Agent running on a host:

Metric collection

1. Edit the redisdb.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory. The following parameters may require updating. See the sample redisdb.d/conf.yaml for all available configuration options.

   init_config:
   instances:
     ## @param host - string - required
     ## Enter the host to connect to.
     - host: localhost
       ## @param port - integer - required
       ## Enter the port of the host to connect to.
       port: 6379
   
       ## @param username - string - optional
       ## The username to use for the connection. Redis 6+ only.
       #
       # username: <USERNAME>
   
       ## @param password - string - optional
       ## The password to use for the connection.
       #
       # password: <PASSWORD>
   

2. If using Redis 6+ and ACLs, ensure that the user has at least DB Viewer permissions at the Database level, Cluster Viewer permissions if operating in a cluster environment, and +config|get +info +slowlog|get ACL rules. For more details, see Database access control.

3. Restart the Agent.

Log collection

Available for Agent versions >6.0

1. Collecting logs is disabled by default in the Datadog Agent, enable it in your datadog.yaml file:

   logs_enabled: true
   

2. Uncomment and edit this configuration block at the bottom of your redisdb.d/conf.yaml:

   logs:
     - type: file
       path: /var/log/redis_6379.log
       source: redis
       service: myapplication
   

   Change the path and service parameter values and configure them for your environment. See the sample redisdb.yaml for all available configuration options.

3. Restart the Agent.

Trace collection

Datadog APM integrates with Redis to see the traces across your distributed system. Trace collection is enabled by default in the Datadog Agent v6+. To start collecting traces:

1. Enable trace collection in Datadog.
2. Instrument your application that makes requests to Redis.

Docker

To configure this check for an Agent running on a container:

Metric collection

Set Autodiscovery Integrations Templates as Docker labels on your application container:

LABEL "com.datadoghq.ad.check_names"='["redisdb"]'
LABEL "com.datadoghq.ad.init_configs"='[{}]'
LABEL "com.datadoghq.ad.instances"='[{"host":"%%host%%","port":"6379","password":"%%env_REDIS_PASSWORD%%"}]'

Note: The "%%env_<ENV_VAR>%%" template variable logic is used to avoid storing the password in plain text, hence the REDIS_PASSWORD environment variable must be set on the Agent container. See the Autodiscovery Template Variable documentation for more details. Alternatively, the Agent can leverage the secrets package to work with any secrets management backend (such as HashiCorp Vault or AWS Secrets Manager).

Log collection

Available for Agent versions >6.0

Collecting logs is disabled by default in the Datadog Agent. To enable it, see Docker Log Collection.

Then, set Log Integrations as Docker labels:

LABEL "com.datadoghq.ad.logs"='[{"source":"redis","service":"<YOUR_APP_NAME>"}]'

Trace collection

APM for containerized apps is supported on Agent v6+ but requires extra configuration to begin collecting traces.

Required environment variables on the Agent container:

See Tracing Docker Applications for a complete list of available environment variables and configuration.

Then, instrument your application container that makes requests to Redis and set DD_AGENT_HOST to the name of your Agent container.

Kubernetes

To configure this check for an Agent running on Kubernetes:

Metric collection

Set Autodiscovery Integrations Templates as pod annotations on your application container. Aside from this, templates can also be configured using a file, configmap, or key-value store.

Annotations v1 (for Datadog Agent < v7.36)

apiVersion: v1
kind: Pod
metadata:
  name: redis
  annotations:
    ad.datadoghq.com/redis.check_names: '["redisdb"]'

    "dockerLabels": {
      "com.datadoghq.ad.check_names": "[\"redisdb\"]",

      "com.datadoghq.ad.instances": "[{\"host\":\"%%host%%\",\"port\":\"6379\",\"password\":\"%%env_REDIS_PASSWORD%%\"}]"
    }
  }]
