Dumping the Pipeline to the Log
Sometimes when you are debugging a service, it is useful to obtain a snapshot of the entire pipeline at a certain point in the service. You can do this by invoking pub.flow:tracePipeline, which puts a copy of the current pipeline in server log. You can invoke pub.flow:tracePipeline from a flow service or a coded service (such as a Java service).
The following example shows the start and end pipeline that was written to the server log with pub.flow:tracePipeline.

To use pub.flow:tracePipeline, take the following general steps
1. In your service, invoke pub.flow:tracePipeline at the point where you want the service to dump a copy of the pipeline to the server log.
2. Set the following parameters:
Key | Description |
level | (Optional) A String specifying the debug levels under which the pipeline is to be written to the log. If the server is running at a debug level lower than the value set in level, the pipeline is not written to the log file. If you do not specify level, Fatal is assumed, which means that the pipeline is written to the log file regardless of which debug level the server is running at. For more information about debug level, see webMethods Integration Server Administrator’s Guide. |
3. Save the service. (If you are using your own IDE, you will need to recompile the service, register it again on Integration Server, and reload its package.)
4. Execute the service. For additional information about pub.flow:tracePipeline, see the webMethods Integration Server Built-In Services Reference.
