You can view all active schedules by clicking on the View option.
Viewing a Sandfly schedule
The schedule will show the lower and upper delays, sandfly types it will run, selection percentage, and the next time it is scheduled to run (in UTC). You will also see a number of runs counter which increments by one each time it runs successfully.
The detail view will also show when the scheduler last run, when it will next run, and how many times it has been executed.
