Currently only the job_id is displayed, it would be more useful if the job_name was shown instead.
Is the for the SQL Server Job Failure alert? Or something else?
It's the text displayed on the Programs tab in DPA. So, drill into day, then hour, then on the programs tab you might see something like: TSQL JobStep (Job 0xB47B0AC9B6128340BD85B1A13A98C671 : Step 1), I think DPA should show the job name.
