<FONT face=Verdana>ServiceOriented Architecture (SOA) enables the dynamic composition of services across heterogeneous platforms through standard Internet protocols.However
it is hard to evaluate service runtime qualities due to the instability and uncertainty of the open Internet environment.Testing is usually exercised in the dedicated testing environment and cannot analyze service behavior in the execution environment.Hence
runtime monitoring is necessary for runtime system status tracking and anomaly detection.The paper is an extension of our previous research on the collaborative monitoring of servicebased systems.It defines a service performance evaluation model using the temporal properties of both atomic and composite service executions.Policies are defined and encoded following the WSPolicy framework.They are enforced at runtime for evaluating the service performance based on the evaluation model.A prototype system is implemented.Experiments are exercised to illustrate the proposed approach and analyze the monitoring overhead.
