Metric Extensions and Management Plug-ins
The 10g and 11g versions of Oracle Enterprise Manager introduced some basic features aimed at helping the product become an enterprise manageability and monitoring framework. However, OEM was, above all, a manageability tool built for Oracle products, with some features extending its capabilities to other target types not supported out of the box. Oracle Enterprise Manager Cloud Control 12c has been completely rearchitected from the ground up to be, first of all, a framework for enterprise manageability. Nearly all functionality for management and monitoring of specific Oracle and third-party products has been built on top of that framework as plug-ins.
