The Web Service Offerings Infrastructure (WSOI) is a monitoring and management infrastructure for the Web Service Offerings Language (WSOL). It extends Apache Axis, an open-source tool for hosting Web services. We present technical details of several WSOI solutions for monitoring Web Services. To pass management information among management parties, we built WSOI serializer and WSOI deserializer modules converting data between formats of Axis’ MessageContext properties and SOAP headers. To perform different monitoring activities for different WSOL service offerings, we implemented Web Service Offering Descriptor (WSOD) as a complement to Axis’ Web Service Deployment Descriptor (WSDD) component. To represent run-time values of WSOL-related management information, we developed WSOI management information model. All these solutions were verified with a prototype implementation of WSOI 2.0 and validated on case studies.
