Policy Rules for Task Operations
The vCenter Server and ESX/ESXi hosts adhere to certain rules when managing tasks in the system.
vCenter Server and ESX/ESXi hosts use the following rules to process tasks:
n
The user performing the task in the vSphere Client must have the correct permissions on the relevant
objects. After a scheduled task is created, it will be performed even if the user no longer has permission
to perform the task.
n
When the operations required by manual tasks and scheduled tasks conflict, the activity due first is started
first.
n
When a virtual machine or host is in an incorrect state to perform any activity, manual or scheduled,
vCenter Server or the ESX/ESXi host does not perform the task. A message is recorded in the log.
n
When an object is removed from the vCenter Server or the ESX/ESXi host, all associated tasks are also
removed.
n
The vSphere Client and vCenter Server system use UTC time to determine the start time of a scheduled
task. This ensures vSphere Client users in different time zones see the task scheduled to run at their local
time.
Events are logged in the event log at start and completion of a task. Any errors that occur during a task are
also recorded in the event log.
CAUTION Do not schedule multiple tasks to be performed at the same time on the same object. The results are
unpredictable.
Managing Events
An event is an action that occurs on an object in vCenter Server or on a host.
Events include user actions and system actions that occur on managed objects in the vSphere Client inventory.
For example, events are created when a user logs in to a virtual machine and when a host connection is lost.
Each event records an event message. An event message is a predefined description of an event. Event messages
contain information such as the user who generated the event, the time the event occurred, and the type of
event message (information, error, or warning). Event messages are archived in vCenter Server.
Typically, event details include the name of the object on which the event occurred and describes the action
that occurred. The object of the event is a link to the object’s individual event page.
NOTE When actions occur on a folder, for example, when an alarm is created on a folder, the related event (in
this case the AlarmCreatedEvent) is visible only in the parent datacenter.
Viewing Events
You can view events associated with a single object or with all objects in the vSphere Client inventory.
The events listed for a selected object include events associated with the child objects. Detailed information
about a selected event appears in the Event Details panel below the event list.
NOTE When the vSphere Client is connected directly to an ESX/ESXi host, the Tasks & Events tab is labeled
Events.
