   Table 1 Event notification parameters

   Parameter	Description
   Name	Name of the event. If the event name is left blank, the system will automatically generate a unique ID as the event name.
   Events	Various types of events. Currently, OBS supports event notification for the following event types: ObjectCreated: Indicates all kinds of object creation operations, including PUT, POST, and COPY of objects, as well as the merging of parts. Put: Creates or overwrites an object using the PUT method. Post: Creates or overwrites an object using the POST (browser-based upload) method. Copy: Creates or overwrites an object using the COPY method. CompleteMultipartUpload: Merges parts of multipart tasks. ObjectRemoved: Deletes an object. Delete: Deletes an object with a specified version ID. DeleteMarkerCreated: Deletes an object without specifying a version ID. Multiple event types can be applied to the same object. For example, if you have selected Put, Copy, and Delete in the same event notification rule, a notification will be sent to you when the specified object is uploaded to, copied to, or deleted from the bucket. ObjectCreated contains Put, Post, Copy, and CompleteMultipartUpload. If you select ObjectCreated, the events ObjectCreated contains are automatically selected. Similarly, if you select ObjectRemoved, Delete and DeleteMarkerCreated are automatically selected.
   Prefix	Object name prefix. The event notification rule applies to objects that have the same name prefix. NOTE: If neither the Prefix nor the Suffix is configured, the event notification rule applies to all objects in the bucket.
   Suffix	Object name suffix. The event notification rule applies to objects that have the same name suffix. NOTE: A folder path ends with a slash (/). Therefore, if you want to configure the event notification for operations on folders and you need to filter folders by suffix, the suffix must also end with a slash (/). If neither the Prefix nor the Suffix is configured, the event notification rule applies to all objects in the bucket.
   SMN Topic	Project: The project that contains the SMN topic you want to select. Projects are used to manage and classify cloud resources, including SMN topics. Each project contains different SMN topics. Select a project first and then a topic.
   	Topic: specifies the SMN topic that authorizes OBS to publish messages. You can create such topics on the SMN management console. NOTE: Once SMN topics are selected for pushing OBS event notifications, do not delete them or cancel their authorizations to OBS. If the topics are deleted or their authorizations to OBS are canceled, the following conditions may occur: a. The subscriber of the topic cannot receive messages. b. Event notifications associated with unavailable topics are automatically cleared. For details, see sections "Creating a Topic", "Adding a Subscription to the Topic", and "Configuring a Topic Policy" in the Simple Message Notification User Guide.
