Adaptability is a key feature of Service-Oriented-Architecture (SOA) Systems. These systems must evolve themselves in order to ensure their initial requirement as well as to satisfy arising new ones. In SOA Systems there are a lot of dependencies between services, but each service is an independent element of the system. In this situation it is necessary not only ensuring that the system fulfils its requirements but also that every system satisfies its own requirements, and dynamically adapting the system when some of them cannot be ensured. In this paper we propose a SOA system, named Service Level Agreement Monitor (SALMon), for monitoring and adapting SOA Systems at run time. SALMon is based on monitoring the services for detecting Service Level Agreement (SLA) violations. The SALMon architecture is composed of three types of components: Monitors, which are composed of measure instruments themselves; the Analyzer, which checks the SLA rules; and the Decision Maker that performs corrective actions to satisfy SLA rules again. These three types of components are mostly technology-independent and the act as service inside of a SOA system making our architecture very scalable and comfortable for its purpose.
