Datadog Tutorials: Log Collection & configuration using Datadog Agent

How to enable Log collection in Datadog?

To enable log collection with an Agent running on your host, change logs_enabled: false to logs_enabled: true in the Agent’s main configuration file (datadog.yaml).

Custom Log Collection in Datadog

Datadog Agent v6 can collect logs and forward them to Datadog from files, the network (TCP or UDP), journald, and Windows channels:

1. Create a new <CUSTOM_LOG_SOURCE>.d/ folder in the conf.d/ directory at the root of your Agent’s configuration directory.
2. Create a new conf.yaml file in this new folder.
3. Add a custom log collection configuration group with the parameters below.
4. Restart your Agent to take into account this new configuration.
5. Run the Agent’s status subcommand and look for <CUSTOM_LOG_SOURCE> under the Checks section.
