You can view tasks and events in your organization to monitor and audit vCloud Directory activities.
vCloud Director tasks are long-running operations and their status changes as the task progresses. For example, a task's status generally starts as Running. When the task finishes, its status changes to Successful or Error.
vCloud Director events are one-time occurrence that indicate an important part of an operation or a significant state change for a vCloud Director object. vCloud Director also logs an event every time a user logs in, and notes whether the attempt was successful or not.
