Another monitoring implementation is based on Web service notification (WSN). Each time a message is exchanged between a service consumer and provider, a report is generated and sent to the internal WSN engine. If there are some subscribers which are interested in the monitoring data, they will be notified by the WSN engine with the monitoring data inside a WSN notify message such as:
