BPEL and Java Cookbook

Defining composite sensors

In this recipe, we will examine how to define composite sensors for tracing purposes. Further, we will also show you the ways to define sensors in a BPEL process. We define composite sensors at the level of SCA when we want to monitor input and output messages of a BPEL process. Composite sensors also provide a convenient way of tracking fields on messages.

Getting ready

As a starting point, we need a BPEL process. We can define a new one or reuse an existing one. For this recipe, we will extend the BPEL process that we used in the Creating a custom logger in a BPEL process recipe.

How to do it…

In this recipe, we will walk through the steps needed to define a composite sensor in SCA:

1. Initially, open the composite of the ...
