Service based systems are intrinsically dynamic as the services deployed by them can be replaced at runtime. When this happens, the Service Level Agreements (SLAs) that regulate the provision of services may also need to change. Following such changes, the monitoring infrastructure that is used to monitor SLAs may also need to be modified to ensure the continuous provision of the necessary runtime checks. This paper presents a framework that supports the dynamic assessment of the monitorability of SLAs terms and the dynamic setup of an appropriate infrastructure for monitoring them following such changes. The monitorability checks are based on comparisons between the SLA terms for specific services and descriptions of the monitoring capabilities of these services which are expressed in languages introduced in the paper. The paper presents a prototype implementation of the framework and the results of a preliminary evaluation of it.
