Many a times one may feel the need to trace ESB events when using itineraries. This will enable you to see how a message is getting processed by the ESB itinerary resolver and if something is going wrong there. The process of enabling this switch is quite simple and it involves the following:
1) Open the BizTalk Configuration file, ie BTSNTSVC.exe.config
2) Add the following section (if one does not exist) and save the file:
<source name=”BizTalk ESB Toolkit 2.0″ />
<add name=”BizTalkESBToolkit20″ value=”4″ />
<trace autoflush=”true” indentsize=”4″ >
<add name=”myListener” type=”System.Diagnostics.EventLogTraceListener” initializeData=”BizTalk ESB Toolkit 2.0″ />
Note: Add a Trace listener. If you don't already have a trace listener configured, add 1 of the many Trace listeners that come out of the box with the .Net framework: (Default, EventLog, TextWriter, Console, Text, etc.) When using the EventLogTraceListener, the initializeData attribute must be set to the source of the Tracing Event. In this case it is the "BizTalk ESB Toolkit 2.0" source.
3) Restart the BizTalk Host Instance.
4) You will now see information and error events in the event viewer. Also if you have debugview running, you will see code traces there.
After enabling tracing, you might still feel the need for tracking. That is, what went where? Every Itinerary Service has a property called ‘Tracking Enabled’ which you’ve got to set it to ‘True’ during the design phase. This sets the stage for tracking an Itinerary Service. Set this property for every single service in an Itinerary as this is false by default. Only those services whose ‘Tracking Enabled’ property is set to true will show up in the database.
Ok, tracking is set to true and my itinerary is deployed. Where do I see this tracing information?
When a service in an itinerary is set for tracking, it is recorded in the BAMPrimaryImport database in the table bam_ItineraryServiceActivity_Completed. the column itineraryBeginTime should be used to sort the results by datetime.
This table gives a snapshot view of the trajectory of the message and if each stage in its path was completed or pending.
