Maintenance schedules identify objects that are in maintenance mode at specific times, which prevents vRealize Operations Cloud from showing misleading data based on those objects being offline or in other unusual states because of maintenance.
Many objects in the enterprise might be intentionally taken offline. For example, a server might be deactivated to update software. If vRealize Operations Cloud collects metrics when an object is offline, it might generate incorrect anomalies and alerts that affect the data for setting dynamic thresholds for the object attributes. When an object is identified as being in maintenance mode, vRealize Operations Cloud does not collect metrics from the object or generate anomalies or alerts for it. In addition, vRealize Operations Cloud cancels any active symptoms and alerts for the object.
If an object undergoes maintenance at fixed intervals, you can create a maintenance schedule and assign it to the object. For example, you can put an object in maintenance mode from midnight until 3 a.m. each Tuesday night. You can also manually put an object in maintenance mode, either indefinitely or for a specified period of time. These methods are not mutually exclusive. You can manually put an object in maintenance mode, or take it out of maintenance mode, even it if has an assigned maintenance schedule. For more information, see Manage Maintenance Schedules for Your Object Workspace.
How Maintenance Schedules Work
Maintenance schedules require that you select the days and time-of-day when updates or other object maintenance occurs. Note that creating a maintenance schedule does not activate the schedule. A maintenance schedule must be part of a policy before the schedule can take effect. For more information, see Policy Maintenance Schedule Element.
