Rule schedules
A rule schedule is based on a calendar that specifies the days and dates the rule is in effect and times it is in effect.
For example, when you are defining a rule, you can set up a calendar schedule based on a daily calendar. Then, you can specify a schedule from 22:00-23:00 (the normal maintenance window for a set of servers). Next, you can set up a rule that looks for a certain message ID generated during that time on a certain group of servers. In the rule, you would also set up an action (for example, an email notification) that is taken if the event occurs (message ID generated during the days/dates and times specified by any of the servers specified).
