Managed Object Description

The TaskManager managed object provides an interface for creating and managing Task managed objects. Many operations are non-blocking, returning a Task managed object that can be monitored by a client application. Task managed objects may also be accessed through the TaskManager.

Properties

Name Type Description
description PTaskDescription

Locale-specific, static strings that describe Task information to users.
maxCollector Pxsd:int

Maximum number of TaskHistoryCollector data objects that can exist concurrently, per client.
recentTask* PManagedObjectReference[]
to a Task[]

A list of Task managed objects that completed recently, that are currently running, or that are queued to run.

The list contains only Task objects that the client has permission to access, which is determined by having permission to access the Task object's managed entity.

The completed Task objects by default include only Task objects that completed within the past 10 minutes. When connected to vCenter Server, there is an additional default limitation that each of the completed Task objects in this list is one of the last 200 completed Task objects.

This property should not be used for tracking Task completion. Generally, a ListView is a better way to monitor a specific set of Task objects. In releases after vSphere API 5.0, vSphere Servers might not generate property collector update notifications for this property. To obtain the latest value of the property, you can use PropertyCollector methods RetrievePropertiesEx or WaitForUpdatesEx. If you use the PropertyCollector.WaitForUpdatesEx method, specify an empty string for the version parameter. Any other version value will not produce any property values as no updates are generated.
