Chapter 22. Tracing Routes
Debugging a route usually involves solving one of two problems:
- a message was improperly transformed
- a message failed to reach its destination endpoint
Tracing one or more test messages through the route is the easiest way to discover the source of these problems.
The route tracing feature of the tooling enables you to monitor the path a message takes through a route and see how the message is transformed as it passes from processor to processor.
Diagram View displays a graphical representation of the route, which enables you to see the path a message takes through it. For each processor in a route, it also displays the average processing time, in milliseconds, for all messages processed since route start-up and the number of messages processed since route start-up.
Messages View displays the messages processed by a JMS destination or route endpoint selected in the JMX Navigator tree. Selecting an individual message in Messages View displays the full details and content of the message in Properties view.
Tracing messages through a route involves the following steps:
22.1. Creating test messages for route tracing
Overview
Route tracing works with any kind of message structure. The Fuse Message wizard creates an empty message, leaving the structuring of the message entirely up to you.
Procedure
To create a test message:
- In Project Explorer, right-click the project to open the context menu.
- Select
to open the New File wizard. - Enter or select the folder in which you want to store the message.
- In the File name field, enter a name for the message.
- Click .The new message opens in the XML editor.
- Fill in the contents (body and header text) of the message.
- On the menu bar, click
to save the test message.
