Configuring metadata collectors
Metadata collectors automatically import data asset information from external systems into Data Catalog.
Metadata collectors provide read-only access to external data systems and harvest information about data assets, making them searchable and discoverable in the catalog. Each collector type is designed for a specific platform and processes that platform's metadata structure. Configuration involves setting up source-system prerequisites and creating a collector record for each platform.

Connection states
Metadata collectors progress through the following states as you configure and validate them:
-
Not configured
The collector has been created but required fields are incomplete. Complete all mandatory fields including system details, connection credentials, and at least one endpoint configuration to move to the next state.
-
Configured
All required information has been provided, but credentials have not yet been validated. The collector moves to Connected status after credentials are successfully verified when the collector runs successfully.
-
Connected
Credentials have been validated and the connection is working. The collector is ready to harvest metadata from the source system.
-
Expired
The connection is broken due to expired authentication details. It is only applicable for authentication methods where this information can be retrieved.
-
