- The start and end times of the effective period are two time points on the same day, and the start time must be earlier than the end time. For example, you can specify 8:00 to 18:00 as the effective period. However, you cannot specify 23:00 to 6:00 of the next day as the effective period.
- The effective period supports only time points in hours, and does not support specifying the effective period by days or dates. For example, you cannot specify March 1 to March 15 as the effective period.
- If you do not specify the effective period, the alert rule takes effect throughout the day.
After the rule is created, you can view it in the rule list and manage it by using the Enable button and the actions in the Actions column.
