There are 3 Job reports.
All jobs, showing last run status, next scheduled run, plus more. Most useful is a warning if a job has run for 20% longer than its recent average run time.
Clicking on a job in the first report displays this report for the selected job.
And the "Timeline" report shows all jobs together in a graphical format and allows stepping backwards and forwards in time to see exactly what was running, when, and whether it ran successfully.
