Service Oriented Architecture (SOA) and web service technology plays a great role in enabling the integration of different systems from different enterprises and platforms. Usually, the service provided to consumers in such systems requires a specific level of quality to be ensured by the providers. So, the consumer and provider enter into a mutual Service Level Agreement (SLA) which is a contract defining the obligations, rights, and penalties between the provider of a web service and a client with respect to the service's quality. Monitoring is required at they service provider and service consumer sides in order to ensure the satisfaction of SLA. This research aims to provide an automated monitoring framework for non-functional attributes of SOA to ensure the trustworthiness of SLA for SOA applications using agent technology. A quality model has been developed as a basis for this monitoring framework. The quality model will identify the related quality attributes and their metrics from different multi-stakeholders perspective. © 2010 IEEE.
