| Rule Name |
Specify the name of the event notification rule.
The name of each event notification rule that is created by using the same Alibaba
Cloud account must be unique in the same region. The name of an event notification
rule must start with a letter and can contain only letters, digits, and hyphens (-).
The name cannot exceed 85 characters in length.
|
| Events |
Select one or more events that can trigger the event notification rule from the drop-down
list. For example, if you want to receive a notification when a specific object is
created or overwritten by copying an object, select CopyObject.
You can configure an event notification rule for a specific object and specify multiple
types of events that can trigger the rule. You can also configure multiple event notification
rules for an object. When you configure multiple event notification rules, take note
of the following items:
- If the multiple event notification rules apply to the same object, the values of this
parameter in these rules must be different. For example, if you select CopyObject
for Events when you create an event notification rule for objects whose names contain
the
images prefix, CopyObject cannot be selected for Events when you create another event notification
rule for objects whose names contain the same prefix.
- If the multiple event notification rules apply to different objects, the values of
this parameter in these rules can be the same. For example, if you select PutObject
for Events when you create an event notification rule for objects whose names contain
the
images prefix and the .png suffix, you can select PutObject or DeleteObject for Events when you create another
event notification rule for objects whose names contain the log prefix and the .jpg suffix.
Notice If you do not specify the version ID when you delete an object from a versioned bucket,
the DeleteObject or DeleteObjects event notification is not triggered. In this case,
no version of the object is deleted. The current version of the object is converted
into a previous version and a delete marker is added to the object.
For more information about the object operations that correspond to the event types,
see Events.
