Using Maintenance Mode
Many resources in the enterprise might be intentionally taken offline. For example, a server might be
deactivated to update software. If vCenter Operations Manager collects metrics when a resource is offline, it
might generate incorrect anomalies and alerts that affect the data for setting dynamic thresholds for the
resource's attributes. When a resource is in maintenance mode, vCenter Operations Manager does not collect
metrics from the resource or generate anomalies or alerts for it.
If a resource undergoes maintenance at fixed intervals, you can create a maintenance schedule and assign it to
the resource. For example, you can put a resource in maintenance mode from midnight until 3 a.m. each
Tuesday night. You can also manually put a resource in maintenance mode, either indefinitely or for a specified
period of time. These methods are not mutually exclusive. You can manually put a resource in maintenance
mode, or take it out of maintenance mode, even it if has an assigned maintenance schedule.
Add a Maintenance Schedule
You can use maintenance schedules to put certain resources into maintenance mode at specified times. The
scheduled maintenance time can be daily, weekly, monthly, or yearly.
To set up a maintenance schedule for a resource, you define the schedule, then you assign the schedule to the
resource, either by adding the resource or by editing it. You can create multiple maintenance schedules, and
you can assign each schedule to multiple resources.
