Monitoring and Analyzing Service Execution from Business Processes: An AXIS Extension

Implementing Business Processes (BPs) with services (and microservices) is nowadays the main way to support the execution of automated activities in processes, both within the organization itself, and externally interacting with customers, suppliers and other participants. In order to do so, it is important not only to model and implement services but also to define Quality of Service (QoS) characteristics for services, to monitor and evaluate their execution. Although there are many proposals for services monitoring and evaluation from the services point of view, there are not many from the BPs perspective. In this paper we present a reference architecture for service monitoring tools, along with a prototype implementation as an extension of the web services execution environment AXIS2. We show that existing service measures and new ones can be defined into the monitor to collect execution data and relate this data with BPs execution, to measure BPs and service execution in an integrated manner.
