Default Standard Attributes

The following table lists the attributes automatically applied to data sent to Datadog by the Agent by each of the RUM, Logs, and APM products, as applicable to the data domain. Optionally, filter the list by product or search by keyword or description text to find the attributes you're interested in.

SourceDomainAttribute NameTypeDescription
ReservedhoststringThe name of the originating host as defined in metrics. Datadog automatically retrieves corresponding host tags from the matching host in Datadog and applies them to your telemetry. The Agent sets this value automatically.

ReserveddevicestringThe type of originating device.
ReservedsourcestringThis corresponds to the integration name, the technology from which the data originated. When it matches an integration name, Datadog automatically installs the corresponding parsers and facets. For example, nginx, postgresql, and so on.
ReservedstatusstringThis corresponds to the level or severity of the data. For logs, it is used to define log patterns and has a dedicated layout in the Log Management UI.

ReservedservicestringThe unified service name for the application or service that is generating the data, used to correlate user sessions. It is used to switch from APM to other products, so make sure you define the same value when you use both products.

You can assign web pages to a service with manual view tracking.
