Once you have configured a module you must configure a job. A job is made up of a Schedule, Worker and Profile.
Schedules define when to perform the data collection as defined in a job. A job defines what schedule, profile and worker to use.
You can create as many schedules as you need.
Schedules have no functionality until they are associated with one or more jobs.
They can be shared across multiple jobs.
You cannot delete a schedule that is currently associated with a job.
Schedules can be recurring or single use.
