Enterprise Architecture Management (EAM) tools play an important supporting role in
IT management of organizations to align their IT infrastructure to actual business needs. The continuously measurement and observation of each layer in an enterprise architecture is critical in order
to achieve an holistic view about the EA operation. This paper describes a concept how to exploit
and extend the metainformation of an IT architecture documented in an EA tool in order to support a
multi-layer monitoring approach that provides traceability and correlation between monitoring data
extracted from several abstraction layers.
