Model-driven self-management of legacy applications

Abstract

Increasing complexity of todays applications and services leads to the emerging trend of self-managing systems. Legacy applications often offer interfaces for manual management and very rarely do provide self-management features. Therefore it is very important to reuse existing management interfaces for achieving self-manageability. This paper presents our model-driven self-management approach of legacy applications. We introduce a framework for model-driven service level management which transforms abstract SLAs defined in UML into concrete SLA descriptions and deploys them for management. These SLAs are used to define the goals for our self-management agent which is responsible for providing feedback control. Its management knowledge is transformed from UML models using also a model-driven approach. © IFIP International Federation for Information Processing 2005.
