Schedules overview
Schedules are associated with SLCs to specify when or for how long monitoring occurs. They are associated with rules to specify when events will be matched against rule criteria and when they will not.
For example, if you do not want a rule to be applied during scheduled downtime, you can create two calendar schedules: one that excludes the downtime and one that includes only the downtime. For the schedule with only downtime, specify an action of "No Operation." For the other schedule, specify an action that produces an alert when the rule criteria are met. Then, associate the two schedules with the rule.
Note: You can create a schedule as part of the process of creating or editing a rule.
