Starting in Strategy 9.3.1, additional logging is available for Distribution Services. The "Info" dispatcher is useful when troubleshooting the job(s) that is/are created for a Distribution Services subscription. The dispatcher can be found in the Strategy Diagnostics and Performance Logging tool as shown below.

Note: This trace is not enabled by default. An existing or new "File Log" destination must be selected for this logging to be used.
When a subscription (tied to a schedule) executes or the "Send Now" feature is utilized, a subsequent job is created for Distribution Services. This dispatcher will log details about this job which was created. When the job runs, a sample of entries logged by the trace are shown below:
