Overview of this book

WSO2 Enterprise Integrator brings together the most powerful servers provided by the WSO2 company for your SOA infrastructure. As an Enterprise Service Bus (ESB), WSO2 Enterprise Integrator provides greater flexibility and agility to meet growing enterprise demands, whereas, as a Data Services Server (DSS), it provides an easy-to-use platform for integrating data stores, creating composite views across different data sources, and hosting data services. Using real-world scenarios, this book helps you build a solid foundation in developing enterprise applications with powerful data integration capabilities using the WSO2 servers. The book gets you started by brushing up your knowledge about SOA architecture and how it can be implemented through WSO2. It will help build your expertise with the core concepts of ESB such as building proxies, sequences, endpoints, and how to work with these in WSO2. Going further, you will also get well-acquainted with DSS data service concepts such as configuring data services, tasks, events, testing, and much more. The book will also cover API management techniques. Along with ESB and DSS, you will also learn about business process servers, the rules server and other components that together provide the control and robustness your enterprise applications will need. With practical use cases, the book covers typical daily scenarios you will come across while using these servers to give you hands-on experience.

Logging the orchestration

Once we know how to configure the logging feature and where to find the log files, we are ready to learn how to trace our service orchestration to help us during the development stage.

There are two ways to trace our flow:

  • Using the log mediator in our sequences or proxies
  • Using the script mediator

Log mediator

This mediator allows you to log all kinds of information related to your service. It is the option you will use most times. This mediator is added to your sequence flow just like any other mediator, and you can find it in the Core section when editing the sequence through the Management Console:

Alternatively, you can find it in the mediator list in the WSO2 EI Tool:
