Learn how Software Catalog discovers services from Datadog Application Performance Monitoring (APM), Universal Service Monitoring (USM), Real User Monitoring (RUM), infrastructure metrics, and logs.

Automatic discovery with APM, USM, and RUM

Datadog Software Catalog is pre-populated with entries detected through APM, eBPF-based autodiscovery with Universal Service Monitoring, and RUM applications.

All automatically detected components appear in the Component Selector within Software Catalog.

APM and USM automatically detect the following component types: service,datastore, queue, external providers, inferred services, and endpoints. APM SDKs identify dependencies of instrumented services and classify them as databases, queues, or third-party APIs—even if those dependencies are not directly instrumented. Custom instrumentation may affect how components are auto-discovered and how the service tag is assigned. To learn more, see APM Inferred Services.

RUM is responsible for discovering frontend apps components.

Managing automatically-named services:

• You can opt-in to inferred entities to filter out entities by type (database, queue, third-party).
• You can optionally remove service overrides such as service:my-service-http-client from your catalog or map.

For information about discovering endpoints, see Discovering Endpoints from APM.

Discover Infrastructure and Logs services

To discover services through Datadog infrastructure metrics or logs, navigate to the Software Catalog Import Entries tab. You can import services from Datadog telemetry containing the DD_SERVICE tag.

After importing, entries appear in the Explore tab. Entries may expire unless you add metadata, such as the owner or contacts, by using the API or the GitHub integration.

To remove imported services from the default Explore view, click Clear Previously Imported Services on the Import Entries tab. This removes all services that do not have metadata or do not have APM, Universal Service Monitoring (USM), or Real User Monitoring (RUM) telemetry.
