   Table 1 Parameters for configuring a bucket inventory

   Parameter	Description
   Inventory Name	Name of a bucket inventory
   Filter	Filter of an inventory. You can enter an object name prefix for OBS to create an inventory for objects with the specified prefix. Currently, only a prefix can be used as a filter. If the filter is not specified, the inventory covers all objects in the bucket. If a bucket has multiple inventories, their filters cannot overlap with each other.
   Save Inventory Files To	Select a bucket (destination bucket) for saving generated inventory files. This bucket must be in the same region as the source bucket.
   Inventory File Name Prefix	Prefix of the inventory file path. An inventory file will be saved in the following path: Inventory file name prefix/Source bucket name/Inventory name/Date and time/files/. If this parameter is not specified, OBS automatically adds BucketInventory as the prefix to inventory file's path.
   Frequency	How frequently inventory files are generated. It can be set to Daily or Weekly.
   Status	Inventory status. You can enable or disable the generation of inventories.

5. Click Next to go to the Configure Report page.

If you enable the notification function, an SMN event notification rule will be created in the bucket where inventory files are stored. You can view details about the rule on the Event Notification page of the bucket. If you disable the notification function or modify the SMN topic, the SMN event notification rule will also be deleted or modified.
