Adapters
Oracle Integration Adapters provide comprehensive, easy-to-use monitoring connectivity with a variety of target types. The adapter enables communication with an enterprise application and translates the application data to standards-compliant XML and back.
The metric extension target type determines which adapters are made available from the UI. For example, when creating a metric extension for an Automatic Storage Management target type, only three adapters (OS Command-Single Column, OS Command-Multiple Columns, and SQL) are available from the UI.

A target type's out-of-box metric definition defines the adapters for which it has native support, and only those adapters will be shown in the UI. No other adapters are supported for that target type.
A complete list of all adapters is shown below.
