Schedule
A time schedule that defines how often the filter specified in a notification or alarm definition is checked and over what period of time.
A schedule allows you to specify the frequency with which the conditions are scanned for notifications to be sent. You must assign a Start date-time to a notification, which will ensure that it runs from that date onwards. You can set a notification or alarm status to Inactive when you do not want it to run.
Example
A catering department typically uses a schedule with a frequency of 30 minutes to alert its staff of catering requests. However, during the month of July when business is slow, they switch to another schedule at a frequency of 4 hours.
