Agent Configuration Files

Agent main configuration file

The Agent v6 configuration file uses YAML to better support complex configurations, and to provide a consistent configuration experience, as Checks also use YAML configuration files. Therefore, datadog.conf (v5) is now retired in favor of datadog.yaml (v6).

Agent configuration directory

Prior releases of Datadog Agent stored configuration files in /dd-agent/conf.d/. Starting with the 6.0 release, configuration files are stored in /etc/datadog-agent/conf.d/<CHECK_NAME>.d/.

Checks configuration files for Agent 6

An example for each Agent check configuration files can be found in the conf.yaml.example file in the corresponding <CHECK_NAME>.d/ folder. Rename this file to conf.yaml in order to enable the associated check. Note that the Agent loads any valid YAML file contained in the folder: /etc/datadog-agent/conf.d/<CHECK_NAME>.d/. This way, complex configurations can be broken down into multiple files. For example, a configuration for the http_check might look like this:

/etc/datadog-agent/conf.d/http_check.d/
├── backend.yaml
└── frontend.yaml

Autodiscovery template files are stored in the configuration folder with the auto_conf.yaml file. For example, for the Redis check, here is the configuration in redisdb.d/:

/etc/datadog-agent/conf.d/redisdb.d/
├── auto_conf.yaml
└── conf.yaml.example

Note: For log collection, the Agent does not accept multiple YAML files that point to the same log source to prevent duplicate logs from being sent to Datadog. In the case where there is more than one YAML file that points to the same log source, the Agent considers the files in alphabetical order and uses the first file.

To preserve backwards compatibility, the Agent still picks up configuration files in the form /etc/datadog-agent/conf.d/<check_name>.yaml, but migrating to the new layout is strongly recommended.

JMX configuration file

JMX Agent checks have an additional metrics.yaml file in their configuration folder. It is a list of all the beans that the Datadog Agent collects by default. This way, you do not need to list all of the beans manually when you configure a check through Docker labels or k8s annotations.
