To Trace a Message Through a Route

Select Window > Open Perspective > Other... > Fuse Integration to open the Fuse Integration perspective as shown in Figure 11, “Fuse Integration perspective”).

	Note
	You can use the Open Perspective icon () in the perspectives tab to access the list of available perspectives.

In Project Explorer, expand the simple-route project to expose the src/main/resources/META-INF/spring/camel-context.xml file.

Select Run As > Local Camel Context (without tests) from the camel-context.xml file's context menu.

In Fuse JMX Navigator, expand Local Processes.

Double click Local Camel Context [id] to connect to the context and expand the elements of your route as shown in Figure 12, “Route elements in Fuse JMX Navigator”).

In Fuse JMX Navigator, select Start Tracing from the camel-1 node's context menu.

The tooling displays a graphical representation of your route in Diagram View.

In Diagram View, drag the nodes to rearrange them, so you can clearly see the route's flow paths.

	Note
	You will have to rearrange the nodes in Diagram View each time you select a different node in Fuse JMX Navigator.

In Project Explorer, expand simple-route/src/data, so you can access the message1.xml and message2.xml files as shown in Figure 13, “Message files in simple-route project”.

Figure 13. Message files in simple-route project

Drag message1.xml and drop it on .../camel-1/Endpoints/file/src/data?noop=true.

As the message traverses the route, the tooling traces and records its passage at each step and displays the results in Messages View.

Repeat Step 9, but this time drag message2.xml and drop it on .../camel-1/Endpoints/file/src/data?noop=true.

In the bottom, right panel, switch from Console to Messages View.

In Fuse JMX Navigator, click camel-1 to populate Messages View with the traces of each message.

As shown in Figure 14, “Fuse Integration perspective's message tracing components”, the tooling draws the route in Diagram View, tagging paths exiting a processing step with timing and performance metrics. Only the metric Total exchanges is displayed in the diagram. Hovering over the displayed metrics reveals additional metrics about message flow:

In Messages View, click a message instance.

The associated step in the route is highlighted in Diagram View. You can step through the message instances to see how a particular message traversed the route and whether it was processed as expected at each step in the route.

The tooling displays the details about a message instance in the top half of the Properties panel and the contents of the message instance, including any headers, in the bottom half of the Properties panel. So, if your application sets headers at any step within a route, you can check whether they are set as expected.

Note

You can control columnar layout in all of the tooling's tables. Use the drag method to temporarily rearrange tabular format. For example, drag a column's border rule to expand or contract its width. To hide a column, totally contract its borders. Drag the column header to relocate a column within the table. If you want your arrangement to persist, use the View Menu > Configure Columns... method instead. To access it, click the icon on the panel's menu bar.

When done, switch back to the Console and click the stop button () in the upper, right side of its pane.
